Software version update – what’s new with Sulis V1.9

We’re happy to announce that we’ve released a new version of our advanced AM design software, Sulis, which brings many new features and improvements to both the Flow and Lattice modules, in particular the ability to design stochastic lattices. Existing users can easily get this update by simply downloading the latest version. Those who want to make use of the two-week free trial can also obtain this from the same link. Let’s look at what’s new with Sulis V1.9.

Import/export of the 3MF file format including the beam extension

Version 1.9 means that our Sulis design for AM software now supports the import and export of the 3MF file format including the beam extension, greatly reducing the file size of Lattice models. The beam extension to 3MF is a brilliant compromise for retaining high tolerance strut definitions when slicing models and file size until build preparation software can handle implicit models.

3MF is a highly viable alternative to the STL file format, which tends to produce large file sizes. With the 3MF beam extension now available in Sulis, our DfAM software, users can now export both a Mesh and Lattice as beams in the same container. This can then be imported into Materialise Magics or similar.

Add stock material to fluid channels

In Sulis 1.9, the Flow module has also been improved to allow users to rapidly define and edit stock material for all flowpaths. This allows for the design of both the as-printed and as-machined geometry.

There are huge benefits associated with this new functionality because pre and post-print 3D models can be used to accelerate the preparation of any post-processing machining required.

Sulis Flow is an easy and quick way to create and edit complex fluid systems. With in-built manufacturability analysis and compensation tools, users designing in Sulis Flow can shorten the overall design cycle and print with confidence.

New stochastic lattice feature

We’ve also made significant upgrades to the Lattice module which means that it is now an ideal design tool for medical implants that contain lattice structures. With Sulis V1.9, users can now create stochastic strut lattices, which significantly extends this module’s capabilities. In addition, the density and connectivity of the struts can all be fine-tuned along with gradient thicknesses to help blend the lattice volume into the solid part.

Stochastic Hip

The Sulis Lattice module which allows users to produce printable lattices in minutes now competes with all leading lattice generation software in terms of functionality.

We’ve created a new video tutorial to support Sulis V1.9 to help users get to grips with stochastic lattices, which you can view below.

Our new stochastic lattice feature has been a much-requested update to our Lattice module. It’s a must-have feature for anyone looking to design medical implants which contain trabecular structures for improved osseointegration.

New TPMS Lattice Types

TPMS lattices (triply periodic minimal surfaces) are a type of surface-based lattice and are defined using equations. The best-known example is the gyroid lattice structure which users of our software already have the capability of producing along with Schwarz P, Schwartz D, Lidinoid and Neovius TPMS types.

With our latest Sulis V1.9 release, users can also now create the Split-P and Primary and Secondary IWP unit cells. These new TPMS types give our users more opportunities to tailor the functional properties of their designs.

TPMS lattices are easy to create in Sulis and can be used in many applications including bioscaffold (for skeletal based lattices) and thermal management applications (for sheet based TPMS structures).

If you have any requests for unit cells you would like to use in Sulis feel free to suggest them to us. Reach out to us via
