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.

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.

Discussions on the Past, Present & Future of Optimizing Topology for Manufacturing – Webinar

Traditional design approaches don’t make the most of new manufacturing methods, like additive manufacturing, which are removing design constraints and opening up new possibilities. The optimal shape of a part is often organic and counterintuitive, so designing it requires a different approach.

Topology optimization lets you specify where supports and loads are located on a volume of material and lets the software find the best shape.

Kick off the year by learning about one of the most exciting advancements in modern design and manufacturing. Join experts from PADT and nTopology for an interactive roundtable discussion on the ins and outs of topological optimization.

Understanding Honeycomb Structures in Additive Manufacturing – Three Papers from ASU and PADT

PADT is currently partnering with Arizona State University’s 3DXResearch group on exploring bio-inspired geometries for 3D Printing. As part of that effort, one of our engineers involved in the project, Alex Grishin, PhD, was a co-author on several papers that have been published during this project.

Below is a brief summary from Alex of each article, along with links.


An Examination of the Low Strain Rate Sensitivity of Additively Manufactured Polymer, Composite and Metallic Honeycomb Structures

PADT participated in the research with the above title recently published in the open-access online journal MDPI ( https://www.mdpi.com/1996-1944/12/20/3455/htm ). This work was funded by the America Makes Program under a project titled “A Non-Empirical Predictive Model for Additively Manufactured Lattice Structures” and is based on research sponsored by the Air Force Research Laboratory under agreement number FA8650-12-2-7230.

Current ASU professor and former PADT employee Dhruv Bhate was the Lead Investigator and wrote the original proposal. Dhruv’s research interests involve bio-inspired design (the study of structures found in nature to help inform human design efforts) and additive manufacturing. Dhruv is particularly interested in the bulk properties of various lattice arrangements. While investigating the highly nonlinear force-deflection response of various additively manufactured honeycomb specimens under compression, Dhruv discovered that polymer and composite honeycombs showed extreme sensitivity to strain rates –showing peak responses substantially higher than theory predicts at various (low) strain rates. This paper explores and quantifies this behavior.

The paper investigates hexagonal honeycomb structures manufactured with four different additive manufacturing processes: one polymer (fused deposition modeling, or material extrusion with ABS), one composite (nylon and continuous carbon fiber extrusion) and two metallic (laser powder bed fusion of Inconel 718 and electron beam melting of Ti6Al4V). The strain rate sensitivities of the effective elastic moduli, and the peak loads for all four processes were compared. Results show significant sensitivity to strain rate in the polymer and composite process for both these metrics, and mild sensitivity for the metallic honeycombs for the peak load.

PADT contributed to this research by providing ANSYS simulations of these structures assuming viscoplastic material properties derived from solid dog-bone test specimens. PADT’s simulations helped provide Dhruv with a proposed mechanism to explain why INSTRON compression tests of the honeycomb structures showed higher peak responses (corresponding to classical ultimate stress) for these specimens than the solid specimens.


Bioinspired Honeycomb Core Design: An Experimental Study of the Role of Corner Radius, Coping and Interface

PADT participated in the NASA-funded research with the above title recently published in the open-access online journal MDPI (https://www.mdpi.com/2313-7673/5/4/59/htm ). This work was guided by former PADT engineer and current ASU Associate Professor Dhruv Bhate.  Professor Bhate’s primary research interests are Bio-Inspired Design and Additive Manufacturing. It was only natural that he would secure a grant for this research from NASA’s  Periodic Table of Life ( PeTaL) project. To quote from the website, “the primary objective…is to expand the domain of inquiry for human processes that seek to model those that are, were or could be found in nature…”

This paper focuses on the morphology of bee honeycombs found in nature –the goal being to identify key characteristics of their structure, which might inform structural performance in man-made designs incorporating similar lattice structures. To this end, the paper identifies three such characteristics: The honeycomb cell corner radius, the cell wall “coping” (a localized thickening of the cell wall at the mouth of each cell seen in a lateral cross-section), and the cell array “interface” (a zigzag pattern seen at the interface of two opposing, or “stacked” arrays).

Most of this work involved material testing and measuring dozens of natural honeycombs (most coming from various museums of natural history found in the United States) at ASU’s state-of-the-art facilities. PADT  contributed substantially by verifying and guiding tests with simulation using the ANSYS suite of software.


A Comparison of Modeling Methods for Predicting the Elastic-Plastic Response of Additively Manufactured Honeycomb Structures

PADT participated in this research found in the reviewed article published in Proceedings of the 29th Annual International Solid Freeform Fabrication Symposium – An Additive Manufacturing Conference.

Figure 14. (left) 2D plane strain model with platens connected to honeycomb with frictional contacts and (right) close-up of an individual cell showing the mesh size as well as corner radius modeled after experimental measurements

The lead investigator was current ASU professor and former PADT employee Dhruv Bhate, whose research interests involve Bio-Inspired Design (the study of natural structures to help inform human design processes) and Additive Manufacturing. In this research, Dhruv investigates discrepancies between published (bulk) material properties for the Fused Deposition Modeling (FDM) of ABS honeycomb structures. The discrepancies arise as substantial differences between published material properties, such as Young’s Modulus and yield stress, and those determined experimentally from FDM dog-bone specimens of the same material (which he refers to as “member” properties).

Figure 4. (left) Homogenization enables the replacement of a cellular material with a solid of effective properties, (right) which can greatly reduce computational expense when simulating engineering structures

PADT’s role in this research was crucial for demonstrating that the differences in base material characterization are greatly exacerbated in nonlinear compression simulations of the ABS honeycomb structures. PADT used both the manufacturer’s published properties, and the dog-bone data to show substantial differences in peak stress under the two assumptions.

6 – An update on outputting results in Ansys Mechanical: 3D Printing Results

To support some new marketing efforts I had to make some different types of results output from models in Ansys Mechanical:

  • A 3D plot on a webpage
    Post 5
  • A physical printout on our 3D Printer
    Post 6

All of the posts are here.

This post is the final, of six, and we finally get to the topic that we get the most questions on: “How do I convert my Ansys Results to a 3D Printed Model.” This article will cover taking Ansys Mechanical FEA results, stress, vibration, and heat transfer, and make a cool 3D plot on Stratasys full-color printers. The process should work on other color printers, but we have only tested it with Stratasys.

3D Printing and Color

Since the beginning of 3D Printing, we have been using a file format called STL. The format only contains the external surface of an object represented as triangles, and it does not support color. But there is good news, a new format, 3MF, or 3D Manufacturing Format was recently introduced to replace STL. It is one of several 3D formats that contain not only triangles on the surface of an object, but they support color information for each triangle. 3MF is for 3D Printing. PLY, OBJ, X3D, and others are for rendering and viewing.

But there is bad news. At this time (2020 R2), no Ansys products support 3MF. So we need to get our results into a format that Stratasys can read color data from, which is the latest version of OBJ. Because of this, we will use our favorite Ansys post-processor, EnSight, to create a PLY file, then an open-source 3rd Party tool, Meshlab, to make an OBJ.

Note 1: As soon as Ansys supports 3MF or OBJ or someone adds a 3MF/OBJ ACT Extension, we will update this article.

Note 2: The steps below are actually covered in the post in Post 2 on how to use EnSight and Post 5 on how to make usable 3D result files. But I’ll repeat them here since you may have only come to learn how to make a 3D result file.

Step 1: Get what you want to print as PLY in Ansys EnSight

Ansys Ensight is a powerful tool that does so much more than make 3D result files. But we will focus on this particular capability because we can use it to get our 3D Printed results.

In Post 2 of this series, I go over how to get a high-quality 2D image from EnSight. Review it if you want more details or if you run into problems following these steps.

Before we get going, one key thing you should know is that Ansys EnSight reads a ton of formats, and one of them is the result files from Ansys Mechanical APDL. So we will start with getting that file.

The program reads Ansys Mechanical APDL result files. These are created when you run Ansys Mechanical and are stored in your project directory under dp0/SYS/MECH and is called file.rst or file.rth. I like to copy the result file from that directory to a folder where I’m going to store my plots and also rename it so I know what it is. For our impeller model, I called it impeller-thin-modal-1.rst.

Once you have your rst file, go ahead and launch EnSight.

That brings up a blank sessions. To get started click File > Open

This will bring up a dialog box for specifying a results file. If you click on the “File type:” dropdown, you will see the long list of supported files it can work with. Take a look while you are there and see if any other tools you use are listed. Of course, Ansys FLUENT and CFX are in there.

But the one we want is Ansys Results (*.rst *.rth *.rfl *.rmg). Chose that, then go to the directory where you put your Ansys result file.

EnSight will read the file and put it in a Case. It will list the results as Part 0 under Case 1.

The left part of the screen shows what you have to work with, and the right shows your model. The “Time” control, circled in green, is where you specify what time, substep, or mode you want. The “Parts” control lets you deal with parts, which we really won’t use. And the “Variables” control, circled in orange, is how you specify what result you want to view.

We want to plot deflection, which is a vector. Click on the + sign next to Vectors, and you get a list of what values you can show. The only supported result for model analysis is Displacment__Vibration_mode. Click on that. Then hold down the right mouse button and select “Color Part” > All.

This tells the program to use that result to shade the part. You should now see your contour.

Our example is a modal result. If you use a structural result file, you will be able to plot the displacement vector, as well as many stress results, under “Scalars”

By default, EnSight shows an undeformed object. If you want to see the deflected shape, click on the part then on the “Displacement” icon above the graphics window. Select the vector result you want to use, displacement in this case. Note, the default displacement factor may not be a good guess, change that till you get the amount of deflection you want.

Note, the default displacement factor may not be a good guess, change that till you get the amount of deflection you want.

The other thing you may want to change is the contours. It has a full library of colors you can change to, but I like the default. What I don’t like is that the min and max may not be where I want them, especially for modal deflection results. The min and max values are the min and max in the result file, and unless you normalize your results, you should tweak the values for your 3D print.

Here is the default color scheme for my 40th mode:

To change the range, click on the contour key and Right-Mouse-Button on the legend, and select Edit… This brings up the Create/edit annotation (legends) dialog. Then click “Edit Pallet…” at the top of that dialog to get to the Pallete editor.

You can make lots of changes here, but what I recommend you do is only change the min and max values. If I set the max to 50, I get this contour on my result:

Next, we wan to save as PLY.

Go to File > Export > Geomtric Entities.

In the dialog, chose PLY Polygonal File Format. This will be the generic format we can convert into something GrabCad likes. Make sure you specify which times or modes you want. By default, it will make a PLY for each one. Also, make sure you have selected the part.

Now you have a color-coded, faceted representation of your results, in a 3D file format. Just not one that GrabCADPrint currently supports.

Step 2: Convert to OBJ in MeshLab

Now we need MeshLab. There are many other tools the read PLY files and output to other formats, but MeshLab has not let me down yet. It is opensource, does everything, and is a pain to use. You will laugh at the user interface. But as ugly as it is, it works. You can download MeshLab from www.meshlab.net. Once you have it installed, follow these steps:

  • Open MeshLab
  • Chose File > Import Mesh
  • Spin it around, look at it. You could scale and transform. But we just want to convert it.
  • Chose File > Export Mesh As
  • Scroll down in the File of Type dropdown and pick Alias Wavefront Object (*.obj)
  • Save
  • Make sure you have only Color checked for Vert. Then click OK

Here is an OBJ file from the example above.

That is it. Import that file into Stratasys GrabCAD Print and have at it.

I printed a different mode shape, but I think it looks fantastic. Click to get the full-resolution version.

Closing thoughts

And this ends our series on getting output from Ansys Mechanical, circa early 2021. It was just going to be one article on getting higher resolution images, but it grew a bit. We hope you find it useful.

Remember, PADT is here to help. We are proud to be an Ansys Elite Channel Partner offering Ansys products across the southwestern US.

PADT has been doing this for a while, and we can offer help in terms of one-on-one support, training, customization, and consulting services. Although this article focused on Ansys Mechanical, we cover the physics across the Ansys product line with experienced engineers in every area. And don’t forget we do 3D Printing as a service as well as product design.
