Editors Note (9/15/2023):
Sadly, Matt Sutton, the author of this tool, is no longer with PADT.
Instead of maintaining the ACT tool that Matt created, we went ahead and built a PyAnsys tool that can be used to output Ansys Mechanical results in a variety of formats, including VRML (*.wrl) which is what most full color 3D Printers can read.
We created a PyAnsys tutorial around the creation of those scripts. You can find the tutorials here:

Please see the “How it works” section below for more information on the structure of the original ACT program, if that is of interest to you.

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

Press Release
This article is getting posted as we also do a press release on the V1 posting of the program to the Ansys Store. You can also find the official press releases as a PDF and HTML.
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.”
