Press Release: PADT Engineers Add Two Patents to the Company’s Patent List, Bringing its Total to 16 in the Last Two Years

People throw the word “innovation” around a lot in the world of technology. Like many buzzwords, it loses meaning over time. Then you do a search and find out that multiple PADT employees have been listed as co-inventor on a past employer’s or PADT customer’s patent. Innovation gets real because you now know you were part of something new and innovative when the US Patent office puts your name in their database.

We just got notification of two new ones and we recently went online to see what other patents we may have missed in 2020 and the first half of 2021. And we found fourteen new patents. Some we knew about but some were a complete surprise to the employee named and us. Sixteen patents awarded in 2020 and 2021 is the most we have had in a two-year period.

We have been making a list of patents where PADT employees are listed as an inventor for over 20 years. To get on the list the patent needs to be granted to the employee before they joined PADT or while at PADT. If you have visited our Tempe offices, you have probably seen our “wall-o-patents” in the entrance where we put up a plaque for every patent granted. We are now using two walls. Our company slogan is in big letters above the first wall: “We Make Innovation Work.”

For engineers, it’s kind of a big deal. It’s a legacy that will not go away. And we could not be more proud of our team and how they have been creative and innovative in the past. It is also a sign of what is yet to come.

The full press release about the two new patents and the other 14 awarded in 2020 and 2021 is below. And, here are links for a PDF and HTML version.

The release lists the 16 new patents with links. You can also view a list of all 68 patents listing PADT employees at: www.padtinc.com/patents

If you are looking for help with your innovation, and want to have a simulation, product development, or additive manufacturing partner where innovation is more than a buzzword, please contact us. If you scan through the patents, you can see that we can help in a variety of industries and a variety of technologies.

Nerdtoberfest 2021: A Parking Lot Full of Hot Dogs, Electric Cars, 3D Printers, and More

What a great way to spend an afternoon. Last week PADT opened its doors… strike that… opened its parking lot for our annual Nerdtoberfest. Our last open house was in 2019 to celebrate our 25th anniversary. Then COVID-19 came and changed everything. Seeing so many people, around 300, in person after so long and sometimes for the first time, is what made this year’s Nerdtoberfest so special.

What is Nerdtoberfest?

PADT has had open houses since our early days in the 1990’s, usually scheduled around an anniversary or a new location. Then, in 2016, we wanted to be part of Manufacturing Month, so we scheduled an open house in October. And not wanting to miss an opportunity to kill multiple birds with one stone we decided to give it an Octoberfest theme. And Nerdtoberfest was born.

It is a celebration of PADT’s customers, partners, and employees and an opportunity for everyone in our little world to gather to learn a little about what we do here at PADT, explore what our customers and partners do, and socialize. Oh, and there is free food and beer as well.

Lots to See and Do

This year we only had our 3D Printing Demo open inside and moved everything else outside. Besides the wonderful food from AZ Barbeque Catering, and drink, we featured:

Stratasys Experience Tour

To help spread the word and make it easier for people to see the latest Additive Manufacturing technology from Stratasys, they built a trailer and packed it full of the latest machines and parts. On top of that, experts on the technology are inside to answer questions. And for over a year now, they have been crisscrossing the US and parking in lots in front of customers, breweries, museums, and a wide variety of other places, all while enforcing strict COVID-19 safety protocols.

The favorite seemed to be the new Stratasys Origin One machine because it adds some new capabilities to the Stratasys line.

ZEV All-Electric Delivery Van

One of PADT’s customers, and an active participant in the Ansys Startup Program, is ZEV. They are an Arizona-based electric battery and vehicle company that is bringing a practical and creative approach to electrification. They brought one of their Mercedes Spring retrofits for people to actually poke and prod. This retrofit takes the internal combustion motor and A/C compressor out and replaces them with batteries, a controller, an electric compressor, and a drive motor. All in the engine compartment. It is a great example of fantastic engineering.

ASU Luminosity Labs

One of the more popular stops was a display from ASU’s Luminosity Lab, an interdisciplinary R&D lab staffed by a group of the most capable ASU students. They work on a wide variety of projects for professors and companies, applying a wide range of skills and tools to solve some of the world’s most pressing challenges. They were featuring the VELOS project, a sensor for exploring parts of the moon that are in permanent shadow.

#HandsOnMetrology Scanning of a Classic’ish Car

We wanted a way let people see how the optical scanning solutions from ZEISS and GOM worked, so we brought an employee’s 2002 Saab convertible in and scanned it right there in the parking lot with an optical scanner. It was a great practical example of the type of reverse engineering you can do with this technology. In fact, it was the same scanner and software that PADT used to scan the engine compartment on the Mercedes Sprinter for ZEV.

PADT’s 3D Printing Services

For a little fun, our 3D Printing Services team built a golf game. Those who could put straight enough got one of several cool parts that PADT made on our new Stratasys H350 SAF Printer. It was harder than it looked but we did give away most of the parts.

The Demo Room

One part of the company that got really lonely during the Pandemic was our Demo Room. It usually saw three or four customer groups a week, and to be honest, was getting a little dusty. So we cleaned it up and opened the double doors to get some good air movement and let people in to see what is new and explore the wide variety of parts that we can make on Stratasys and EOS machines.

New PADT Website Preview

Yes, we are finally updating our website. We know, the current one is old enough to almost have a retro feel to it. We are working with Founder’s Workshop to reimagine how we can share information with everyone and we are just short of the MVP stage, so we wanted to show it off.

Positive Energy was Everywhere

People used different phrases to describe it, but the most common comment I heard was the overwhelmingly positive energy everywhere. Maybe it was the joy of eating a well-cooked hotdog, or seeing 3D laser scanning in action, being able to quiz and expert on the latest 3D Printing technology or just realizing that the person you have been talking to on Zoom for 18 months actually has legs. There were a lot of smiles

Here is a slideshow of some of the images we captured:

Press Release: NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

When we applied for a NASA Small Business Technology Transfer (STTR) grant with Arizona State University in 2018 we had high hopes around that the idea of developing simulation and manufacturing techniques that would allow engineers to mimic structures found in Nature. Today’s win of a rare Phase III grant from NASA exceeded those hopes and further showed the space agencies’ interest in the research that PADT, ASU, and now Penn State are engaged in.

Inspired by the research of former PADT engineer and now ASU professor, Dr. Dhruv Bhate, the idea was to take a look at how nature uses repeating structures and responses to loads to optimize structures and to use 3D Printing as a way to create the derived shapes, growing geometry just as nature does. That Phase I was received well and led to a Phase II grant in 2019 to dig specifically into lattice structures. In addition to that work was the development of a topological optimization tool that could look at multiple types of loads and create aperiodic lattice topologies.

Researchers at NASA like those results enough to then grant PADT a Phase III project to further the development of the optimization tool and to connect it to a fluid-thermal optimization tool developed at Penn State under a separate NASA project. The study is called “Thermo-Fluid and Structural Design Optimization for Thermal Management” and it will look at creating structures that are strong, light weight, and have the thermal performance required for difficult launch and space-based missions.

You can read more in the press release below or here: PDF | HTML.

We are exceptionally proud of all three phases of this project because they show:

  1. PADT’s ability to work with academia for R&D that results in useful tools
  2. Our deep and broad understanding of simulation across physics
  3. How our unique expertise in Additive Manufacturing can be combined with our simulation knowledge to turn theory into practical hardware.

If you have needs in any of these areas or are just looking for a strong R&D partner that can help make your innovation work, reach out to PADT.

NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

The Grant is a Continuation of PADT’s Topology Optimization Research, Which Will Fund “Thermo-Fluid and Structural Design Optimization for Thermal Management”

TEMPE, Ariz., September xx, 2021 ─ In a move that acknowledges its excellence and expertise in R&D for numerical simulation and 3D printing, PADT today announced NASA has awarded a $375,000 Phase III Small Business Technology Transfer (STTR) grant for PADT to collaborate with Penn State University. The partners will expand research into thermo-fluid and structural design optimization to provide engineers who design next generation launch and space crafts with better ways to design more robust and efficient structures that experience loading fluids, forces, vibration, and temperatures.

The Phase III STTR grant is a continuation of the original $127,000 Phase I and $755,000 Phase II grants awarded to PADT and ASU’s Ira A. Fulton Schools of Engineering in August 2018 and December 2019 respectively. This is PADT’s 17th STTR/SBIR grant since the company was founded in 1994.

“Furthering our research in simulation and 3D printing for topology optimization and thermal management is critical to the future of aerospace development,” said Alex Grishin, Ph.D., consulting engineer, PADT. “This Phase III award underscores how valuable NASA found the work we did earlier with ASU and signals their desire to have PADT work with other universities to transform it into a tool that engineers can use to design better launch and space-based structures.”

The objective of the joint effort between PADT and Penn State University is to successfully demonstrate the integration of 3D data output from Penn State Mechanical Engineering Experimental and Computational Convection Laboratory’s (ExCCL) thermo-fluid optimization code, developed under a NASA Aeronautics Fellowship grant, into PADT’s topology optimization tool. The latter was developed by PADT under the STTR Phase II contract.

In Phase II, PADT partnered with Arizona State University (ASU) to develop and test a novel shape optimization tool that used a unique methodology for topological optimization, taking both the thermal and stress response of a part into account. 3D printing was also used to create the geometry produced by the optimization approach. Phase III will connect PADT’s tool to Penn State’s tool, which uses genetic algorithms to better handle the optimization found in thermo-fluid problems.

“Taking our tool and connecting it with the optimization capability that Penn State developed has the potential to benefit aerospace design engineers worldwide,” said Tyler Shaw, PhD, PADT’s VP of Engineering and the leader of the group responsible for this work. “This project will take the joint research one step closer to delivering on an optimization approach that, just as in nature, takes into account all loads, regardless of physics.”

The ultimate goal of the project is to continue research with internal and government funding to create a commercial product that engineers can use as an alternate way to optimize the shape of structures that see loading from multiple physics.

3D Printing Ansys Mechanical Results with PADT’s “AM Result Printer” Ansys ACT Extension

One of the first things PADT did when we got our first multi-color 3D Printer was figure out how to convert a result in Ansys Mechanical to something to be printed. If you go back to earlier blog posts (2014, 2020) on the topic and find that our earlier methods were – well cumbersome would be kind. There was no easy way to get Ansys Mechanical results into a file that contained color contour information on the surface that could then be printed with a color Additive Manufacturing system.

That is when our Matt Sutton stepped up and used Ansys ACT skills and knowledge on graphics programming to create simple plugin that converts any result object on a solid object in Ansys Mechanical into a 3D Manufacturing Format (3MF) file: AM Result Printer. The 3MF file can be read by Stratasys Grab CAD, the standard tool for Stratasys color systems and, because 3MF is an accepted platform across systems, it should work with any newer color additive manufacturing system.

The plugin is available at the Ansys Store here. It is free, and the download file contains installation and user instructions, or read on to learn more.

Installation

Instaillation is simple. For each installation of Ansys Mechanical, do the following:

  1. Download the ZIP file from the Ansys store
  2. Extract the files in some scratch location
  3. Go into 2021_09_00-3MF-Writer\AM_Result_Printer_v1\Incoming
  4. Then also expand the bianary.zip file. This contains the plugin for various versions of Ansys Workbench
  5. You need the right Visual C++ Redistributable package, so doublick on “vcredist_x64.exe” to make sure its installed. Follow the prompts until its done.
  6. Add the extension through Ansys Workbench. On the project page, go to Extensions > Install Extensions

Go into the binary folder and find the “Additive Manufacturing Result Exporter.wbex” in the proper version folder.

Then to into Extensions > Manage Extensions and click the check box for the Additive Manufacturing Result Exporter.

Now, when you got into your model in Ansys Mechanical, you should see the extensions listed at the top, and if you right-mouse-click on the Solution part of you model, it should be a choice.

How to use it

Make sure you insert any result objects you want to 3d Print and scope them to the things you want printed. Then, for each 3MF file you want, insert an “AM Result Export” into the tree. Then select the result you want a file for, they type of contour, and the number of bands.

When everything is ready, Generate the model to create the file or files.

How it works

This little tool is a great example of using Opensource libraries with the Ansys ACT interface. Matt used the VTK and lib3mf libraries. When you generate the object, the following happens:

  1. Converts the mechanical mesh scoped to the result body to a VTK unstructured mesh.
  2. Export out the result data from the result object as nodal values to a temporart file.
  3. Apply these nodal values to the VTK mesh.
  4. Contour using an appropriate VTK algorithm.
  5. Extract the VTK contour data as a series of triangular facets.
  6. Group the facets by color for banded, or extract the individual vertex colors for smooth.
  7. Write that data to the .3mf format using the lib3mf library.

Need more information?

If you would like more information or have any questions or need support on the tool, please email info@padtinc.com or give us a call at 480.813.4884.

This is also a great example of the type of custom application that PADT creates for a wide variety of customers to improve and enhance their simulation experience. If you have any questions on software development or customization needs around simulation, please reach out to info@padtinc.com or call 480.813.4884 as well.

Free Extension Designed to Export Ansys Mechanical Results as Color 3MF Files for Additive Manufacturing Released by PADT

Custom Plugin Allows Users to Create 3D Printed Full-Color Models with Results Contours

TEMPE, Ariz., August 31, 2021 PADT, a globally recognized provider of numerical simulation, product development, and 3D printing products and services, is pleased to announce the initial release of the Ansys Mechanical extension, AM Result Printer.  Written by PADT’s Scientific & Technical Computing team in the Ansys Customization Toolkit (ACT), AM Result Printer allows users to select any Ansys Mechanical results they have extracted from their model and output a 3D manufacturing format[, or 3MF, file. The extension is available on the Ansys Store today.

“PADT is an industry leader in off-the-shelf and custom 3D printing and simulation tools and products,” said Tyler Shaw, PADT’s VP of Engineering. “When customers requested a way to export Ansys Mechanical results as color 3MF files, we saw an opportunity to develop a custom program and share it with our community for free.”

The PADT Scientific & Technical Computing team work on small extensions like the AM Result Printer, large standalone programs, and a multitude of tools that make simulation more efficient and useful. The AM Result Printer extension was written by Matt Sutton, PADT’s Lead Developer for Scientific & Technical Computing using the tools provided by Ansys through their API and several publicly available libraries for working with tessellated geometry and the 3MF format.

Any Ansys Mechanical user can install the extension for free by first downloading it from the Ansys Store where it is listed as “AM Result Printer.”  The download includes installation instructions. Once installed, users can easily add an AM Result Object to any result object and then create the 3MF file. This file can then be used in any additive manufacturing system that support the 3MF format and prints in full color, like the Stratasys J55, J826, J835, and J850 PolyJet systems.

“This simple program is a fantastic example of how our software experts, who are also Ansys experts, create applications that greatly enhance the already strong capabilities of Ansys products,” said Sutton. “We’re proud to make this powerful tool available to the Ansys user community.”

Girl Gang Garage: Custom Car Rebuilds + 3D Scanning + 3D Printing

What do you get when you cross a 1961 Volvo PV544 retro-look car with a sleek 2019 Volvo S60 T8 Polestar Engineered sedan – and why would you ever do that?

You get a custom head-turner hybrid vehicle designed to get people talking, especially about women in automotive trades. That’s because this blended vehicle project is being disassembled, redesigned and rebuilt by an all-female team based at Girl Gang Garage in Phoenix Arizona.

Bogi Lateiner and Shawnda Williams, co-owners of Girl Gang Garage, stand next to the stripped-down body of a 1961 Volvo PV544 that will soon be retrofitted on the chassis of a brand-new 2019 Volvo S60 T8 Polestar Engineered sedan. The rebuild project provides a rare hands-on learning opportunity for women of all ages and skill levels, from around the U.S., to come and learn (or improve) skills in welding, cutting, transmission work, body repair/painting, electronics, upholstery and more. (Image courtesy Girl Gang Garage.)

Girl Gang Garage founder and co-owner, Bogi Lateiner, TV host of Motortrend’s All Girls Garage and Garage Squad shows, is well on the way to transforming these vehicles as the third major public project she has undertaken. Along with co-owner Shawnda Williams, Lateiner offers women of all ages, experiences and skill levels the chance to lend a hand, learn a tool, and possibly discover a new career-path in the automotive trades.

Lateiner and Williams apply well-honed old-school skills but have been increasingly interested in the possibilities offered by today’s digital workflow. That’s why early in 2021, after conversations with the fellow re-build team at Kindig-It Custom Car Fabrication, Lateiner reached out to Stratasys to see how they might work together to incorporate 3D printing in the PV544 project.

At Stratasys, Pat Carey, Senior Vice President Americas Products & Solutions, and Allen Kreemer, Senior Strategic Applications Engineer, were immediately onboard with the chance to help Girl Gang Garage move into the digital world while widening their circle of women with automotive skills and interests. They loaned the team an F370 FDM 3D printer and accompanying support-removal SCA tank and offered to supply filament material for a two year try-whatever-you-want time period. Moreover, they pulled together a volunteer team of women across the country who could support the effort on multiple fronts.

A Virtual Team and a Digital Workflow

The team includes engineers whose day-time jobs have them working at Stratasys, Link3D, Autodesk, Xerox, Collins Aerospace and Ford Motor Company or as independent consultants. Printer installation and local support is handled by PADT Inc, a Stratasys reseller and 3D printing/design/simulation company located just 16 miles away from Girl Gang Garage. In addition, members of Women in 3D Printing offered to coordinate many of the publicity efforts and even sponsor a related design competition targeted at young women in high schools and colleges who are learning CAD skills. (More on that to come.)

During the first few Zoom meetings that introduced Lateiner and Williams to the technical capabilities of the different team members and the printer, the basic rebuild plan was presented: strip the PV544 down to bare metal (removing every mechanical and electrical component), disassemble the S60 down to the chassis, engine, drive-train and hybrid motor system, and figure out how to make the two sections fit!

Traditionally, that workflow depended strictly on the classic tools of the trade, from cutting wheels and a Sawzall to hand-grinders and pneumatic drills. Those components are still coming into play on the current project under the skilled eye of the Girl Gang Garage leaders, but now complementary digital processes are being added.

It Starts with Scanning

PADT recently became a reseller of GOM 3D scanning hardware and software tools, and the timing was perfect to bring the new handheld Tscan Hawk system on-site. Operating with both red-line and blue-line (different wavelength) laser scanners plus stereo cameras, the Tscan Hawk captures millions of spatial 3D-point-coordinates (termed clouds of data) which are converted into a standard STL mesh file format for several end-purposes. The red lasers generate measurements across medium to large surfaces while the blue-wavelength sensors capture fine detail, with accuracy down to 20 microns.

GOM Inspect software records reference points, captures the individual coordinate data and allows interrogation of that data to provide dimensions, such as the distance between the engine frame mounts or the diameter of the hole into which the headlamp fits.

 (Images courtesy PADT Inc.)

These three images show a) the reference-point data that appears on the laptop screen as the shape of the PV544 vehicle’s underside is captured, b) the completed scan showing the 3D details of the as-built sheet metal and c) a report page from GOM Inspect software with dozens of dimensions extracted from the scan, such as the length of the trunk opening and the width of the opening available for the engine mount. The scan data, if exported as an STL file, could be sent directly to a 3D printer – though for this project the team is not printing the full body. Instead, subsets of the scan are being used for reverse engineering, where the data works as the basis for creative design elements to be printed and perhaps painted or plated.

To do so, the scanned data is be brought into a surfacing package such as Geomagic Design X or Innovmetric PolyWorks. Those software tools let users convert the STL mesh into an IGES surface, which can then be brought into a CAD package as the basis for a new solid model.

Not for the real build but as a fun example, here is a possible headlight-rim with the letters “Girl Gang Garage” cut out as a circular repeat pattern, that could be backlit with LEDS to customize the build. The design and dimensions are based on the maximum inscribed circle fitted by the GOM Inspect software inside the given opening. (In future blog posts, we’ll show examples of the CAD team’s actual 3D printing results.)

Scanning has many other purposes and capabilities. If CAD data were available for the actual vehicle, those files could be imported, overlaid on the captured data, and compared, alerting the user to deviations between intended and actual dimensions – a very common use of GOM Inspect software.

Next Steps

Every Thursday through Sunday, volunteer women come to Girl Gang Garage and learn to use cutting tools, welders, sanders and more, making daily progress toward the completed hybrid PV544. (All women are invited to come help and learn, at no cost – just sign up to get involved and get yourself to Phoenix.) Here are a few glimpses into the work as of early April – much more has been done but stay tuned for the next blog post as we show off elements of the S60 sedan, scan data being used for reference, and details of the design contest.

The Many Flavors of 3D Printer Maintenance, and Why it’s So Important

Just over a year ago, PADT, like most every other engineering company, shifted rapidly into minimal on-site-operations mode. As the PADT 3D Printing Application Engineer, I worked from home while requesting support from our manufacturing group for running benchmark parts on our Stratasys fused deposition modeling (FDM) filament and PolyJet resin printers.  Whether those parts were created on the F370, F450, F900 or J55 printers, they spanned a wide range of part size, function and material. It was an interesting time, but software tools like GrabCAD Print made remote part set-up possible, and the on-site team kept everything running under some often-challenging conditions.

I’ve been back in the office for about a month, so I’m tending to tasks that were, out of necessity, put on a backburner while our company did high-importance projects such as printing a ton of PPE visor frames. Now it’s time to do some printer maintenance that got a little delayed beyond the recommended run-time schedule.

For our Stratasys J55 full-color PolyJet printer, while all the standard components were cleaned and checked after every print, we stretched the recommendation period for replacing the wiper blade, the roller-waste collector, and both filters in the compact ProAero Air Extractor that contributes to making this printer truly office-friendly. Now I’ve checked those off as done.

Bring in the Printer Maintenance Experts

Other steps should only be done by a professional from the Service Department at your reseller or from Stratasys. When they come on-site to perform Preventive Maintenance for your printer, do you know what goes into this, and the kind of tasks that keep your system humming along?

It’s similar to practicing good automotive ownership: checking the air in your tires, changing the oil every 5,000 miles or so, replacing brake pads before they’re so thin that you have to turn the rotors, etc. Some jobs you do monthly, some yearly and some on general principles to avoid future trouble which inevitably occurs during the critical stage of a project.

Stratasys F450 Print-Head Gantry Assembly (Image courtesy Stratasys)

Here are some of the tasks our PADT service technician performs from the 12-month Preventive Maintenance Checklist for a Stratasys F450 industrial FDM printer:

  • With the printer powered off, clean the canister drives, gantry fans and electronics bay ventilation fans (kind of like cleaning out the ventilation area under the front of your refrigerator – which we all do regularly, right?) Also, inspect the head cable and heat shields, verify X-Y belt tensions, and replace the vacuum filter.
  • With the printer powered on, verify voltage levels, fan speeds and Z-Zero calibration, inspect the flicker brush assemblies and clean and lubricate the Z-axis leadscrew.

When the two-year point rolls around, these tasks are repeated plus another set is added, such as:

  • With the printer off: Replace the filament guide tubes, Kapton seals, X and Y bellows seals, oven lamps, air-pressure regulator diaphragm and all compressed-air system filter elements.
  • With the printer on: Adjust the air pressure and airflow, verify the oven blower operation and perform filament load-time tests.

And at the four-year mark, all of the above are completed plus such tasks as “replace the X and Y belts.” At every service appointment, too, the technician verifies that the current version of the printer control software has been installed, and that the user has the latest application software, whether Insight or GrabCAD Print. All in all, we’re talking more than 50 check points and tasks that keep the printer running smoothly.

High Expectations from Good Maintenance

I have to admit that when I get into my car, I expect the engine to idle smoothly, the air-conditioning to generate chilled-air, and my driveway to be free of oil spots. However, that expectation is only realistic if I or my mechanic has done due diligence with regular inspections and taken action when certain conditions show up. Checking for dirty spark plugs or a cracked distributor cap will maintain engine performance. If the serpentine belt is showing signs of wear, I’d better replace it rather than risk losing both power steering and air-conditioning on some far-off road in the desert on a beastly summer day. And worn rings, pistons or gaskets could all contribute to that oil leak.

And so it goes with 3D printers. First, the importance of avoiding down-time is huge for most manufacturers and factors into both production planning and a smooth workflow for printing prototypes. Second, if you’ve paid for a Stratasys-authorized Service Plan, you get guaranteed response time when something does go wrong (say you accidently melted filament into the print-head because you didn’t mount the tip correctly – life happens). Third, with a PM contract, a trained technician steps you through every aspect of the printer’s operation, inspection and cleaning whether done daily/weekly/monthly by a program engineer or by the system operator.

Stratasys offers three levels of contract service for almost all of its 3D printers, now covering the gamut from FDM and PolyJet to SLA, DLP, and the new Selective Absorptive Fusion (SAF, a polymer powder-bed fusion technology). Those levels are Sapphire, Emerald, and Diamond which can each be purchased for multi-year coverage.

Generally speaking, service offerings include:

  • On-site technical service
  • Spare parts
  • Priority service scheduling
  • Discounted user-training
  • Discounts on printer heads

Customers also win with hardware updates, optional backup printing services, predictable maintenance expenditures for easier budgeting, and more.

It’s not in my budget to buy a new car every year or even every couple of years, so regular, professional automotive inspection and maintenance is critical to me. It is to customers in the additive manufacturing world, too. So, to paraphrase that diamond-jewelry advertisement, “Now you have a friend in the 3D printer business: Stratasys.” Find out more about service contracts and the details of preventive maintenance by contacting 3DPSAL@PADTinc.com.

Workflow for Creating a 3D Printed Medical Model with Stratasys

For decades in the medical world, surgeons and their professional support teams have relied on X-rays, computed tomography (CT) scans and magnetic resonant imaging (MRI) data when performing their pre-surgical planning approach. These diagnostic tools have been literal lifesavers, yet the resolution and 2D perspective of these images can make it difficult to determine the full details of anatomical geometry. Subtle, critical abnormalities or hidden geometries can go unnoticed when viewing flat films and digital displays.

With the advent of 3D printing, many surgeons are now using 3D models for both surgical planning and patient communication. While cost is the primary hold-back, such models are seeing increased use. In addition, efforts are underway to quantify the benefits of reduced operating room time/expense and improved patient outcome; see Medical 3D Printing Registry (ACR/RSNA). Supporting this concept are the high-resolution, multi-material PolyJet 3D printers from Stratasys.

But how does the patient’s CT and MRI data become a unique 3D printed model you can hold in your hand? How do you segment out the areas of interest for a particular analysis or surgical model? This blog post describes the necessary steps in the workflow, who typically performs them, and the challenges being addressed to improve the process every step of the way.

Data Acquisition of Patient Anatomy

When we think of imaging throughout the decades, X-ray technology comes to mind. However, classic single 2D images on film cannot be used to drive 3D models because they are qualitative not quantitative. The main options that do work include the series of x-rays known as CT scans, MRI data, and to a lesser extent computed tomography angiography (CTA) and magnetic resonant angiography (MRA). Each approach has pros and cons and therefore must be matched to the proper anatomy and end use.

CT scans comprise a series of x-rays evenly spaced laterally across a particular body section, typically generating several hundred image files. These can be quickly acquired and offer high resolution, however, they do not do well displaying different types of soft tissue, and the process relies on extended exposure to a radiation source.

Sample multiple digital images generated as a CT scan is performed (Image courtesy nymphoenix/Shutterstock.com.)

Typical CT resolution is 500 microns in X and Y directions, and 1mm in Z. This is readily handled by Stratasys printers; for example, the print resolution of the J750 Digital Anatomy Printer is 42 microns in X, 84 microns in Y, and 14 to 27 microns layering in Z, which more than captures all possible scanned features.

Computed Tomography Angiography (CTA) involves the same equipment but uses a contrast agent. With this approach, brighter regions highlight areas with blood flow. This process is superior for showing blood vessels but does not differentiate tissue or bones well.

MRI data is based on a different technology where a strong magnetic field interacts with water in the body. This approach differentiates soft tissue and shows small blood vessels but is more expensive and not effective for capturing bone. Similarly, Magnetic Resonant Angiography (MRA) uses a contrast agent that can track small blood vessels which are important for identifying a stroke but cannot register tissue. MRI scans may also include distracting artifacts and offer poor regional contrast.

A final source of digital imaging data is Positron Emission Tomography (PET). Here, radioactive material is attached to a biologically active area such as cancer; the data obtained with sensors is useful but very local – it does not show surrounding tissue.

Segmentation: Conversion from DICOM to STL format

Whether generated by CT or MRI equipment, anatomic image data is stored in digital files in accordance with the Digital Imaging and Communications in Medicine (DICOM) standard. Two aspects of this standard are relevant to 3D printing medical models: DICOM files include patient-specific, HIPPA-protected information, and the data in the individual images must be merged and converted into a solid model, with the areas of interest defined and partitioned.

Various software packages and services are available that will convert DICOM data into an STL model file (standard format for 3D printer input) while stripping out the personal identifying information. (The latter must be done to comply with HIPPA regulations: never send a DICOM file directly to any service bureau.)

Segmentation involves partitioning a digital image into distinct sets of pixels, defining regions as organ, bone, blood vessel, tumor, etc., then grouping and combining those sub-sections into a 3D model saved as an STL file. Not only does this format offer more meaningful information than a stack of separate images, but it can then be exported for 3D printing.

The standard unit of measure for identifying and segmenting the different regions within the combined 3D series of CT scans is a Hounsfield unit. This is a dimensionless value, defined as tissue density/x-ray absorption; for reference, water = zero, a kidney =+40 and bone = +1000.

Human guidance is needed to set threshold Hounsfield levels and draw a perimeter to the area of interest. You can define groups with the same threshold level, cut out certain areas that are not needed (e.g., “mask” the lungs to focus on the spine), and use preset values that exist for common model types. Typically, a radiologist or trained biomedical engineer performs this task, since correctly identifying boundaries is a non-trivial judgement task.

A particularly challenging task is the workflow for printing blood vessels, as opposed to bones or organs. The output from CTA/MRA imaging is the blood pool, not the enclosing vessel. In this case, users need third-party software to create a shell of X thickness around the blood pool shape, then keep both model files (pool and vessel) to guide printing the vessel walls and their internal support structure (which, on the Stratasys J750 Digital Anatomy Printer, is soluble and dissolves out.)

So far, just a few medical segmentation software packages exist:

  • Materialise Mimics Innovation Suite is internationally known for its excellence in image analysis and allows you to write scripted routines for automating repeated aspects of the segmentation tasks. There are also tools for interpreting images with metal artifacts, designing support connections between parts, measuring specified features, and rendering a view of the resulting 3D model.
  • Synopsys Simpleware ScanIP is a 3D image segmentation, processing, and meshing platform that processes data from MRI, CT, and non-medical imaging systems. Simpleware ScanIP removes or reduces unwanted noise in the greyscale images, allows cropping to the area of interest, supports both automated and user-guided segmentation and measuring and includes API scripting. Modules are available for Cardio, Ortho, and Custom solutions.
  • Invesalius 3 is open-source software that can reconstruct CT and MRI data, producing 3D visualizations, image segmentation, and image measurements in both manual and semi-automated modes.
  • Embodi3D/Democratiz3D is an online service that lets you upload a series of CT scans, select a basic anatomy type (bone, detailed bone, dental, muscle, etc.), choose the free medium-to-low resolution or paid high resolution conversion service, and receive the link to an automatically generated STL file. (Users do not interact with the file to choose any masking, measuring, or cropping.) The website also offers downloadable 3D printable models and 3D printing services.

Note that these packages may or may not have some level of 510K FDA clearance for how the results of their processing can be used. Users would have to contact the vendors to learn the current status.

Setting up the STL file for printing

Most of the segmentation software packages give you options for selected resolution of the final model. As with all STL files, the greater the number of triangles, the finer the detail that is featured, but the model size may get too large for reasonable set-up in the printer’s software. You may also find that you still want to edit the model, either to do some hole repairs or smoothing, slice away a section to expose an interior view, or add mechanical struts/supports for delicate and/or heavy anatomy sections. Materialise Magics software will do all of this readily, otherwise, adding a package that can edit STL files or create/merge geometry onto an STL file will be useful.

Whoever is setting the file up for printing needs to make a number of decisions based on experience. For Stratasys Connex3, J55, J8-series or J750 Digital Anatomy Printers, the process begins by bringing the file into GrabCAD Print and deciding on an optimized build orientation. Next, colors and materials are assigned, including transparent sections, percentages of transparent colors, and flexible/variable durometer materials, which can be for a single part or a multi-body model.

For the J750 Digital Anatomy Printer in particular, users can assign musculoskeletal, heart, vascular, and general anatomies to each model, then choose detailed, pre-assigned materials and properties to print models whose tactile response mimics actual biomechanical behavior, such as “osteoporotic bone.” (see Sidebar).

I tested out the free online Democratiz3D segmentation service offered by Embodi3D. Following their tutorial, I was able to convert my very own DICOM file folder of 267 CT images into files without patient ID information, generating a single STL output file. I chose the Bone/Detailed/Medium resolution option which ignored all the other visible anatomy then brought the resulting model into the free software Meshmixer to edit (crop) the STL. That let me zero in on a three-vertebrae section of my lower spine model and save it in the 3MF format.

Lastly, I opened the new 3MF file in GrabCAD Print, the versatile Stratasys printer set-up software that works with both FDM (filament) and PolyJet (UV-cured resin) printers. For the former case, I printed the model in ivory ASA on an F370 FDM printer, and for the latter, I was able to assign a creamy-grey color (Red248/Green248/Blue232) to give a bone-like appearance, printing the model on a J55 PolyJet office-environment printer.

Experience helps in producing accurately segmented parts, but more features, such as AI-enabled selections, and more online tutorials are helping grow the field of skilled image-processing health professionals. Clarkson College (Omaha, NE) also recently announced the first Medical 3D Printing Specialist Certificate program.

Sidebar: J750 Digital Anatomy Printer

The Stratasys J750 Digital Anatomy Printer uses PolyJet resin 3D printing technology to create parts that mimic the look and biomechanical response of human tissue, organs and bones. Users select from a series of pre-programmed anatomies then the material composition is automatically generated along with accurate internal structures. Pliable heart regions allow practice with cutting, suturing and patching, while hollow vascular models support training with guide wires and catheters. General anatomy models can replicate encapsulated and non-encapsulated tumors, while bone structures can be created that are osteoporotic and/or include regions that support tapping, reaming and screw insertion.

Currently the Digital Anatomy Printer models present in the range of 80 to 110 Hounsfield Units. Higher value materials are under development which would help hospitals create phantoms for calibrating their CT systems.
