Leveraging Formlabs Elastomeric Materials to Create a Library of Lattice Responses
The fifth NFL Helmet Challenge Design for Additive Manufacturing eSeries Guest Blog
It seems like every day there are new products hitting the market that incorporate amazing lattice designs. From football helmets to running shoes, companies are eager to be on the cutting edge of additive manufacturing and consumers flock to products with promises of improved performance and eye-catching aesthetics.

It’s true that intelligent lattice design and additive manufacturing have created a new frontier in product development. But how can product designers and companies ensure their marketing promises aren’t just hot air? Designing with lattices opens up a world where properties of an object that used to be set by material selection can now be varied by changing aspects of the lattice. Material properties like durometer and modulus of elasticity can be varied spatially across a single part manufactured from a single material.

Product designers may utilize this capability to step outside the bounds of traditional stacked foams, using lattices to alleviate tension or provide dynamic support. Even responses that may seem undesirable on the surface can provide benefit in certain applications. Can the inclusion of a lattice that buckles at a certain force prevent injuries?

In our webinar, learn how to take your next project from concept to product by creating lattices with Formlabs printers and integrating them into products using nTopology workflows. We’ll give you an overview of how to determine elastomeric latticed material properties using simple tests and show you a process to leverage Formlabs 3D printers and nTopology design software to create latticed products that deliver on their hype.
