Renishaw manufactures advanced 3D printers and software, but it also produces crowns and bridges through its dental services business. Renishaw leverages mesh processing software Polygonica to enable more reliable automation for this particular application, which used to be completed with lost wax casting and CNC milling processes. David Turner, Renishaw’s Software Development Manager, explained that the company runs into mesh integrity issues with small holes and gaps, non-manifold bodies, floating shells and voids, and incorrectly oriented triangles.
“The amount of mesh detail is really key to us because we’ve got tens of thousands of parts coming in monthly. That takes up a lot of server space plus the amount of bandwidth it takes to shift these parts around our manufacturing system is huge. Also, the amount of time to process those parts and create laser paths that we can actually then build the parts with goes up massively.”, said David Turner. He also referred that Renishaw uses Polygonica to help with other mesh modeling needs, such as product identification and tracking, creating nesting algorithms, hub placement, and creating abutments. Renishaw also used Polygonica to develop its ADEPT craniomaxillofacial design tool for additive manufacturing, which you can watch about in the following video:
