Getting to know PADT: Zeiss and Geomagic Scanning Products

 This post is the fourteenth installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

As engineers, we spend most of our time trying to get geometry we create in a computer out into the real world as a physical part.  But sometimes, we need to go the other way. We need to get real geometry into a computer.  Once there we can measure it accurately, modify it, simulate it, or use it as a reference to design something that connects to it.

There is a lot of power in being able to quickly and accurately digitize objects. Here at PADT we make that power available to our customers through our Scanning & Reverse Engineering Services and through the sale of the same tools we use to our customers so they can bring scanning in-house.  In particular, we represent high-fidelity scanners and software from ZEISS and Geomagic.

Creating Accurate Digital Models

Our own experience with scanning taught us the hard way that the key to creating accurate digital models was outstanding hardware and powerful software. There are a lot of solutions that take shortcuts to “make it easier” or to keep cost down.  We tried those, they didn’t work.  That is why we settled on ZEISS and Geomagic tools because they do work, and they work well.  The process of digitizing geometry is simple: put the part in front of a scanner, scan it, and get a point cloud.  The reality is that the right hardware and software determines if you will spend days to get gigabytes of useless data or if you spend a few hours to get a useful and accurate computer model that you can work with.

Structured Light Scanning

The scanners from ZEISS and Geomagic both use a technology called Structured Light Scanning. Some also refer to it as Fringe Projection.  The way it works is that you couple a precise light projector with a high-resolution digital camera. The projector projects a series of lines onto the part and the camera records how that pattern distorts. The pattern is varied to get more resolution.  The part is also rotated or projector-camera assembly is moved around the part. Either way, light is projected onto the surface in a pattern, and the distorted pattern is recorded.

Then some sophisticated math is used to turn how the pattern is distorted into a highly accurate collection of points across the surface of your part.  That is the end result of Structured Light Scanning – millions of points that sit on the surface of your part.

World Class Scanning Hardware

The quality of the hardware used is key to success in this area.  To be accurate you need a very precise projector, an accurate digital camera (called a sensor in this application) and world-class optics.  Which is how we ended up working with ZEISS.  Their optics are second to none, and they have developed or acquired the best projector and sensor technology in the industry. Combine that with their famous German engineering and quality processes, and you end up with a robust and accurate solution that is second to none.

Portable Laser Scanning with Touch Probe May Be a Perfect Fit

Some parts are too big for structured light scanning. Or sometimes you may want to measure a few locations on a larger part.  For those situations, the ZEISS T-SCAN CS Handheld scanner is the perfect fit.  It combines an optical tracking unit, a handheld laser scanner, and a touch probe to give you the flexibility you need to take measurements on large objects. The touch probe is especially useful for measuring key features and locations.

Geomagic Capture Scanners Deliver Portability and Cost Savings

Many of our customers needed a portable solution that cost less and was really only needed to get geometry into their CAD systems.  We searched and found that the Geomagic Capture scanners from 3D Systems are a perfect balance between functionality and cost, delivering high value.

Proven Scanning Software

Once the points have been captured, no matter how accurately that was done, they are useless if you don’t have the right software tools. Geomagic 3D software and hardware tools are industry leaders for one simple reason: they work. For reverse engineering, inspection, scanning, cleaning up point clouds, or working with mesh-based geometry, no other set of solutions comes close to the capability and robustness of the Geomagic tool package.  We use three packages:

Geomagic Design X: Reverse Engineering

Geomagic Wrap: Point Data to Polygon Models

Geomagic Control: Inspection Automation

Let’s Talk about, And Look At, Your Scanning Needs

Scanning is a technology, by its natures, that begs to be seen.  If you have ever considered adding 3D Scanning to your workflow, or want to know how 3D Scanning can help your productivity, accuracy, and quality, contact us for a discussion and a demo.

Press Release: New Digital Manufacturing Facility for On-Demand Delivery of Production Quality Parts Opened at PADT

PADT is very proud to announce that our new manufacturing facility that uses 3D Printing technology to make production parts in volume, is open for business.  When we bought our first Additive Manufacturing machine in 1994 we dreamed of the day when we could have several machines quickly making complete plastic parts in one step. Carbon’s Carbon’s Digital Light Synthesis™ (DLS) was the technology we were waiting for. It is here now, and we are now making real parts with injection molded quality.

We chose to leverage Carbon’s technology because of the three key differentiators in their system:

  1. Digital light projection is much faster than a laser or print head.
  2. Oxygen permeable optics enables accurate project while keeping the part from sticking to the optics.
  3. Programmable liquid resins produce parts with excellent mechanical properties, resolution and surface finish.

What every engineer wants: fast, strong, and accurate.  And because it is Additive Manufacturing, no tooling is required and shapes that can be created that are impossible to manufacture with traditional methods.  This is the promise of 3D Printing for production, and we can’t wait to see what our customers do with it.

Please read the press release below for more details on the opening of our facility.

You can also find more information here:

Please find the official press release on this new partnership below and here in PDF and HTML

Now is the time to explore production using Additive Manufacturing.  If you have plastic parts that you want to manufacture using 3D Printing, contact Renee Palacios at renee@padtinc.com or 480.813.4884.

New Digital Manufacturing Facility for On-Demand Delivery
of Production Quality Parts Opened at PADT

A Carbon Certified Production Partner, PADT Enables Customers to Make Cost-Effective Parts Quickly with Near-Injection Molded Material Properties

TEMPE, Ariz., June 21, 2018 ─ Realizing the long-term promise of 3D Printing to replace traditional manufacturing as a way to make production parts, Phoenix Analysis and Design Technologies (PADT) today announced the launch of On-Demand Manufacturing with Carbon. As a certified Production Partner of Silicon Valley-based Carbon, PADT can now deliver to its customers cost-effective, quality parts in volumes of between 2,000–5,000 in about one week, using Carbon’s Digital Light Synthesisä (DLS) technology and the Carbon production system.

“Since we started in 3D Printing almost 25 years ago, we have dreamed of the day that we could use additive manufacturing to move beyond prototyping and deliver production parts to our customers when they need them, the way they need them,” said Rey Chu, co-founder and principal, PADT. “Carbon’s DLS technology has made this possible by giving us a faster process that creates parts with the same properties as injection molding.”

Core to On-Demand Manufacturing with Carbon is Carbon’s proprietary DLS technology, which changes the way companies design, engineer, make and deliver products. Carbon’s novel approach uses digital light projection, oxygen permeable optics, and programmable liquid resins to produce parts with excellent mechanical properties, resolution and surface finish. A significant advantage of using the approach is that no tooling is required. High-quality parts are produced without the time or expense of creating molds, and shapes that cannot be made with injection molding can be created using Carbon’s DLS technology.

“Our goal is to deliver true, scalable digital fabrication across the globe, enabling creators to design and produce previously unmakeable products, both economically and at scale,” said Dana McCallum, head of Production Partnerships at Carbon. “PADT has a long history in the industry and a strong reputation for engineering excellence. We’re thrilled to have them as a certified Carbon production partner.”

PADT’s on-demand manufacturing is backed up by in-house product development, inspection, simulation and injecting molding expertise. All parts are produced under its quality system, and its in-house Computer Numeric Control (CNC) machining lets the company complete any critical feature creation on-site with no delays.

PADT’s Digital Manufacturing Facility, the Southwest’s first true “3D Printing factory,” is now open to customers. For more information about On-Demand Manufacturing with Carbon, please visit PADT’s site here or call 1-800-293-PADT. For more information about Carbon, visit www.carbon3d.com.

Recently Published: Sound in the Workplace, Leveraging AZ’s Western Resorts for Business, and Learning to Say What you Do.

Three new articles have recently been posted to the  Phoenix Business Journal, with three very different topics. Click the links to read. If you like any of these, or any of the pieces we put out there in the PBJ, please share them on social media!

“Such a cool space, but I can’t hear a thing.” That is not just old age talking. More and more attention is paid to the look of a work area and not to the sounds in that area. And it can impact productivity. That is “Why we should pay more attention to noise in our workspaces.

There are a lot of choices in the Valley for entertaining out of town business guests. “Phoenix’s Western resorts: A business tool to build your brand on” is a look at why you should take them to a local western-themed resort, and how to leverage the experience.

Too many companies these days load up their company description with buzzwords and catchphrases, completely passing by the opportunity to tell people what they do. I advocate that if you are coming up with marketing material, you should “Learn to define what your company does.”

Making Connections, how Far Downtown Phoenix has Come, and a Podcast Appearance on Business in Arizona

Lots of new content to share out there from PADT on that is published by other people.

Two blog posts in the Phoenix Business Journal went out since the last update:

We meet fellow business people that become part of our network almost every day. At work, at dinner, and at events for our kids. Sometimes we even make connections while being driven to dinner. And those connections can pay off someday. In “Make connections wherever you can, even with your Lyft driver” I explore the impact of our more connected world.

I was at a business dinner, off on some tangent about the types of early-stage capital available in the state when I didn’t hear what my dinner companion said because the train behind him was too loud. Looking over his shoulder, past a crowd of pedestrians, I could see the Phoenix Art Museum was glowing yellow in the sunset behind the train. And then it hit me over the head – Phoenix has a real downtown now. I ponder this change in “Street side pizza, trains, and museums: downtown Phoenix, how far you have come.

We were lucky enough to be asked to participate in this great local podcast for Business in the Phoenix area. Here is the description: Eric Miller, Principal & Co-Owner at PADT, talks about product development and angel investing. PADT is a globally recognized provider of Numerical Simulation, Product Development, and 3D Printing products and services. Links can be found here:

10 Great New Features in ANSYS Mechanical 19.0 and 19.1

ANSYS Mechanical version 19.0 has been available since late January 2018, while version 19.1 was released in May. If you haven’t had a chance to check them out, we thought it would be helpful to list what we see as 10 of the top newest features. We’ll start with five new features from version 19.0 and will then round it out with five from version 19.1.

ANSYS Mechanical 19.0

1. 4 Cores HPC Solving with No Additional Licensing

Previously, you were limited to solving on 2 cores at a maximum without having additional ANSYS HPC or HPC Pack licenses. That limit has been raised to 4 cores at 19.0.
To utilize the cores while solving, from the Solution branch in Mechanical click on the Tools menu, then Solve Process Settings. Click the Advanced button. Set the Max number of utilized cores to 4 and click OK.

2. Topology Optimization Includes Inertial Loads

Topology optimization became a native option in ANSYS Mechanical in version 18.0. Topology optimization allows us to perform studies in which we preserve stiffness while reducing weight, for example. Since inertia loads are now supported in a topology optimization, one type of problem we can now solve is starting with geometry that has a mix of an inertial load (gravity in the downward direction) along with additional loading such as forces or pressures.

Solving the topology optimization and moving to the verification step we can see the optimization results (shape and contour results plot) for the combined loading.

The ability to include inertia loads adds quite a few more problems that can be considered for topology optimization.

3. Small Sliding Contact

The idea here is that if we have confidence that the contact and target elements within a contact region will not slide very much, we can turn on the small sliding assumption. This speeds up the computations because less checking is needed for the contact elements during the solution. It’s activated in the Details view for one or more contact regions. We’ve seen some marginal improvements in solution times for a couple of test models. It’s clearly worth trying this if it applies to your simulations.

4. Element Birth and Death

We now no longer have to use APDL command objects to incorporate element birth and death. If you’re not familiar with what this is, it’s the ability to selectively deactivate and/or activate portions of the finite element model to simulate forming operations, assembly, etc. Further, the implementation is fantastic in that unlike with the old MAPDL implementation, we no longer have to manually keep track of which elements have been ‘killed’ or made ‘alive’. The postprocessing in Mechanical 19.0 automatically displays only elements that are alive for a given results set.
Here is how it is implemented in the Mechanical tree, under the analysis type branch:

The entities to be killed or made alive can be selected by geometry or Named Selections. There is a handy table that shows the alive or dead status for each Element Birth and Death object once they are setup:

This animation shows a temperature results plot and demonstrates how the killed elements are made alive and automatically displayed when postprocessing:

5. Clipboard Tool

This new menu pick gives us an improved method for tasks such as selecting multiple faces. Rather than having to carefully pick all of them at once or use a combination of named selections, we can now simply select the faces that are easy to pick, add them to the clipboard, rotate the model, select more faces now that they are in view, etc.

Once all the desired faces are in the Clipboard, we simply use the Select Items in Clipboard dropdown and we can now assign a load or mesh control, etc. to the desired faces.

Note there are convenient hot keys for Adding to, Removing from, and Clearing the clipboard, shown in the screen captures of the menu dropdowns above.

ANSYS Mechanical 19.1

6. Granta Design Sample Materials

Version 19.1 adds a whole new set of sample materials from Granta. To access them, open up Engineering Data, click on the Engineering Data Sources button, and then click on the Granta Design Sample Materials button. This adds a lot more sample materials than have been available in Engineering Data previously.

7. Materials folder in Mechanical

You’ll see a new branch in the tree in Mechanical 19.1: Materials. All materials that are part of your Engineering Data set will show up in this branch. For each material defined, we can click on the Material Assignment button or right click as shown here:

One the new Assignment branch is created for a material, we can then select the bodies for which that material should be assigned. Each material has its own color which can be changed in Engineering Data if so desired.

Important note for Mechanical APDL command users: Assigning material properties using the Materials branch results in all parts with the same material property having the same MAPDL material number. This is different from prior behavior in Mechanical in which each part in the geometry tree had its own material number identified with the ‘magic’ parameter name matid. Parameter matid now no longer is unique for each part if materials area assigned using the Materials branch. There is a new ‘magic’ parameter named typeids which identifies the element type number for each part in the tree. This new parameter is actually a 1x1x1 array parameter rather than a scalar parameter, so to make use of it in a command snippet we need to add the dimension (1) to the parameter name, like this:

thtest1=typeids(1)

or

et,typeids(1),solid65

8. Result Tracking During Solution

A new, useful capability is to be able to view a result item on a body, while the solution is running. You can now insert certain results items under Solution Information and view the status of the results while the solution is progressing. If birth and death is employed it will even display just the elements that are alive as the solution progresses. Here is an example of a temperature plot on a body while a transient solution is in progress:

9. Save Animations to .wmv and .mp4 Formats

We now have two new options besides the old .avi format for exporting animation files. The .mp4 and .wmv formats both tend to produce smaller files than .avi format. When you click on the Export Video File button the new options are available in the dropdown:

10. Solution Statistics Page

Finally, there is a new Solution Statistics page, available under Solution Information when a solution has completed. This is a quick and easy way to view performance information from your solution and helps determine if more cores or more RAM could be beneficial in future solutions of the same model. Here is an example:

Conclusions

These are just a few of the enhancements that have been implemented in versions 19.0 and 19.1. These should help you be more productive with your solutions in ANSYS Mechanical as well as increase your capacity for simulating reality, and creating new geometry when it comes to topology optimization.

Getting to Know PADT: Medical Device Product Development

 This post is the thirteenth installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

The development of medical devices is difficult.  The regulatory challenges, quality requirements,  and technical hurdles of dealing with the complex system that is the human body make the processes required to bring products for this industry to market unique and difficult. That is why PADT has a team in our Engineering Services department that is focused on one thing: Medical Device Development.

If you read our article on Product Development Services or watched the flashy video then you know how we do product development differently.  That our processes and staff are proven, that we are all about solving problems and using project management intelligently, all geared towards to deliver a complete solution.  Every one of those characteristis is true for our Medical Device team as well, we just add more on top to give our customers the confidence to work with us on their product development.

We sometimes get involved in projects all the way from defining specifications to coordinating with manufacturing. We also provide assistance at every step along the way: testing, concept modeling, trade studies, material evaluations, quality consulting, design for manufacturing, and testing to name just a few areas that we can help.  That is one of the things that makes PADT unique in this particular industries. Most companies will only do the full product development, whereas we serve as an outside resource for the whole thing, or only where our customers need additional help.

Solving the Tough Problems

There are a lot of medical device design companies out there.   We often get asked how we can stay busy in this industry, especially when we are not located in a hot-bed of device design and manufacturing like California, Boston, or Minneapolis.   The answer is simple.  Customers from those locations and other markets come to Tempe to work with us because we are good at solving the difficult problems.  Most of this capability comes from the skill and experience of our staff.  They know their stuff and they know how to systematically investigate and solve the most difficult problems.  They also have access to advanced tools like 3D Printing and world-class simulation in-house. Combine this with solid project management and a well-provisioned lab, and you have a winning combination.

Understanding Medical Devices

The other key requirement for anyone doing medical device product development is a thorough understanding of Medical Devices themselves. Every industry has its buzzwords and acronyms, but medical devices are in a category all their own. They are a bridge between the world of mechanical engineering and medicine, so they terminology and operating environment are different then say aerospace devices or consumer products.  To work on medical devices you have to understand all the physics, manufacturing, software, and electronics that every mechanical device needs. You also need to understand biology and treatment.  PADT’s staff walks that fine line between the two worlds and often serves as a translator between the end user (doctors and nurses) and engineering, even within our customer’s organizations.

Quality Centric

Quality is the most important, and least understood, unique aspect of Medical Device Product Development.  Any team attempting to bring a product to market who does not know ISO 13485 and the FDA requirements will fail.  We also know that Quality is a tool, not a barrier.  We understand the client’s quality system and adapt our processes as efficiently as possible to get value from the entire quality process.

Let us Engineer your Medical Device Innovations

Here is a powerpoint we put together last year with even more information:

Product development for medical devices is something we are just plain good at.  Large corporations and startups come to PADT to because we get the job done.  You can see some great case studies here that tell the story in the words of our customers.  Reach out to us via email (info@padtinc.com) or give us a call at 480.813.4884 and we can talk about how our team can help engineer your medical device innovation.

Understanding Big Data: You have it, but how do you get value from it?

The idea of Big Data, so much information that traditional data analysis tools cannot process it, has been around for a while now. We collect data, we store it, and we plan to use it. There must be value in all that information. Many of us are actively saving terabytes of data. In “Understanding Big Data: You have it, but how do you get value from it?” I take a look at the four critical questions you can answer with your mountains of ones and zeros.

The Beatles and other world-changing revolutions

The problem with most business revolutions is you do not realize you are in the middle of one until you are in the middle of one. We are in the middle of so many right now, it is hard to keep up. While taking a flight and listening to some Beatles, I had a thought about “The Beatles and other world-changing revolutions.”
