Gen3D is excited to announce that it has been acquired by Altair. Sulis will be integrated into Altair Inspire and we will not provide an updated version of Sulis going forward. However, all existing and new Sulis licenses and support remain valid and will be honoured. The current standalone software is still available and you can purchase Sulis online on this website.

demo files for sulis

Demo files to support your trial of Sulis.

Here are four example files to help you get the most out of your trial of Sulis, Gen3D’s design for additive manufacturing software. You can also access many video tutorials via the Sulis dashboard and we offer a free DfAM course too which have some interactive tutorials using Sulis.

Before, during, or after your trial, you have the opportunity to engage with a Gen3D expert. Do you have an application in mind? Would you like to see a demo? Or would you like to purchase a license? You can purchase Sulis online, or get in touch by using the webchat function. Or you can send us an email via

Demo 1: Gyroid heat exchanger

This demo file provides a method to create a manifold gyroid heat exchanger and contains two imported STEP bodies. The first body represents the internal core of the heat exchanger. This body will have a double skin gyroid problem component attached to it and two offset surface problem components used to create the manifolding. To recreate this design from scratch, follow along to this tutorial video.

To export the entire object for printing, you will need to add a solid problem component to the second imported body. Need help? Get in touch via chat or send us an email.

Demo 2: Lattice disk

This problem file helps you design a lattice sample disk. There are 5 STEP files with different lattice definitions which you can modify to explore the capabilities of Sulis. Some lattices have cartesian coordinate systems and others have cylindrical coordinate systems.

To avoid a singularity at the centre, we’ve added a cylindrical model with a solid problem component. The offset solid problem component is used to separate the segments of the cylinder and create a solid section on the outside. You can modify the thickness of the solid section by modifying the offset distance.

Demo 3: Robot end effector

This problem file contains a definition required to design a robot end-effector. The file contains a series of imported STEP files including the suction cups and platform for the moveable objects. The flowpaths are then created using Sulis Flow. The fluid channels can be manipulated by editing their properties in the edit node and edit flow path panels. The flowpaths can be exported as STEP files from the export panel.

Demo 4: Strut Heat Exchanger

This problem file demonstrates the use of Sulis AM-Pro to create a heat exchanger that combines a hollow lattice core with combined flow path inlets. The fluid channels are designed to be self-supporting during printing, however, you can scale up the exported mesh file to create a larger part or increase the channel diameter.

An external outer model has a solid problem component on it, however, 50% of the external struts are visible to highlight the internals of the heat exchanger. We recommend generating this structure at a resolution between 0.1-0.2 and to add a single smoothing step using the Gaussian option. Check the decimate box and export as .3MF to minimise the file size.
