Everyone wants their prototypes to look polished, as opposed to looking like 3D-squirted weekend afterthoughts. The combination of Delrin and a Laser Cutter make this easy, especially if you learn a few tricks-of-the-trade that will make your assemply pop, both functionally and aesthetically.
Last time, we took a deep dive into fabbing parts with Delrin and a typical 40-watt laser cutter, and we discussed some of the constraints of the material. More recently, [Gerrit] gave us a close look at the material itself. It’s been about a year since our first post, but the list of tricks is far from complete.
If you’re just getting started in this domain, let me introduce you to two classic techniques for laser-cut prototypes: puzzle-piecing and the T-nut-slotting. While these techniques are tried-and-true, I hope, fearless reader, that they’ll leave you hungry for something cleaner, something more refined. If that’s the case, read on!
