Lattice

My partner and I chose a beer koozie to lattice the surface. Koozie was chosen for both functional and aesthetic reasons. It would benefit from having a lattice surface because there would be open spaces through which heat can escape, thus not warming up the drink the koozie holds. Having a lattice would result in interesting and fun designs that would allow us to explore which ones can be printed and not.

​

We modeled the koozie using SolidWorks and used nTopology to create the lattice. All parts were printed on FormLabs Printer 2.

 

For our first drraft, we used a gyroid pattern for the lattice. However, we soon realized that it would be extremely difficult to print due to overhangs, and so, we changed the pattern to schwarz instead. The period of the pattern was set so that the circles would be teardrop-shaped. Because PreForm software aggressively adds supports to the parts, supports were added manually instead, adding only where necessary. The final design is shown as below, as well as the images of the design with supports added.
