Tip: You can also Move and Rotate the lattice to further define its position within the context of the model. In the Setup tab, choose your desired "Cell Shape" from the three options. I ended up going with the Gyroid option, and I set the size to 6mm, which felt appropriate per the size of the phone case. I also made a 2mm offset around the fingerprint sensor and a 3mm offset around the camera opening. I made a 2mm offset around the edge, which will ensure the backing and edging can join together. Select an edge or face as the reference, then add the offset. This approach will ensure the result is feasible and doesn’t affect critical geometry. I like to define the Offsets first before exploring the different Lattice options.
Otherwise, the lattice would apply to the whole phone case. This is why I set the backing of the phone case as a "New Body" in the previous step. Select the body - back of the phone case - to apply the lattice to. Once the extension is active, you’ll find the Volumetric Lattice feature in the Modify dropdown. However, you can start a 7-day free trial of the extension if you'd like to try it out. It’s important to note that this feature is only available with access to the Product Design Extension. Consider using blue painter’s tape or a glue stick on a glass build plate if you have issues with the filament sticking.įusion 360 now supports the creation of Lattice structures, which are the crisscross patterns that make 3D printed objects both lighter and stronger. The first few layers are very critical as TPU does not always stick well to all build platforms. You’ll want to lower your cooling fan speed to ~20%, and up your printing temperature to 230 degrees celsius. Out of all the flexible filaments I’ve used over the years, Polymaker has proven to print with the best results and the least amount of fuss. If you’d like a functional phone case, you’ll want to purchase flexible TPU filament. PLA and ABS will not work well for 3D printing a phone case, unless your simply printing it for fun.
TPU can be a bit tricky to print if you're used to printing in PLA. The good news is that TPU is both an affordable and capable material to 3D print on hobbyist-level FFF (FDM) 3D Printers.
Phone Cases are often injection molded with TPU. Follow along with my step-by-step tutorial on YouTube, or follow the detailed guidance in the Instructable below. Create your own custom 3D Printable Phone Case in Autodesk Fusion 360.
