Advanced tutorials for designing lattices – combining lattice types

Hollow strut lattice and Intersecting Gyroid Lattice

Sulis Lattice can be used to easily create complex lattice structures. Since its release in 2020, this module has become one of the simplest ways to generate high-resolution complex lattice structures for additive manufacturing. We’ve created many tutorial videos to help you grasp the basics so now it’s time to get more advanced. In this blog post, we have four ALL-NEW advanced video tutorials demonstrating how to combine and manipulate lattice types.

1. How to design interpenetrating strut lattices

Every object can be copied and pasted in Sulis. Using the same shortcuts that are found in common applications, ctrl+c and ctrl+v can be used you create copies of models that have lattice components attached to them. Once you have two copies of a lattice structure, you can combine the lattice types and begin to manipulate the lattice properties to create new and interesting lattice types.

In this example, we combine two different strut lattice unit cells to create interpenetrating strut lattice structures. These types of lattices have been shown to have increased structural properties when compared to either of the two base lattices. You can read more about this in more detail in this academic journal paper by researchers at Sandia National Labs.

2. How to combine TPMS and strut lattices

This tutorial shows you how to copy-and-paste lattice structures and modify the lattice parameters to create lattice structures that combine lattice types. In this case, we show you how to create combined gyroid and strut lattices.

We have also created examples combining strut and stochastic lattices, as shown in the following image.

3. How to create intersecting gyroids

Once you have mastered the copy and paste operation allowing you to combine lattice structures, the next stage is to modify different parameters of the lattices.

In this example, we show you how to use the inverse checkbox to create intersecting gyroid structures. These structures create two separate bodies. These can either be printed in different materials and have been shown to have beneficial properties in many applications. One example is to maximise energy storage in 3D printed Supercapacitors. Read more in this Journal paper from Simon Fraser University in Canada.

4. How to make hollow strut lattices

Another feature within Sulis Lattice is the ability to add and subtract different lattice structures from one another. This can be achieved by toggling the Solid checkbox within each of the lattice panels. Subtracting surface lattices from one another is a great way to open up more fluid domains within the structure. The following example shows you how to create hollow strut lattice structures.

Hollow strut lattices can be used for a number of applications. They can be used for heat exchanger cores or they can be filled with a secondary material to achieve superior material properties.

If you’re interested in learning more about how Gen3D can help you design fluid flow or lattice components, get in contact at www.gen3d.com and one of our sales representatives or applications engineers will be happy to give you a demo of our Sulis software. We also offer training and consultancy primarily in the field of design.
