3Dprint switches

From: John Foust: Sunday, February 01, 2015 2:23 PM The part are generally functional, but there's significant "banding," where the individual extrusion layers are visible in the result. This is made worse by the need to orient the part to maximize the mechanical strength of the result. The color choices are generally quite limited, too. Admittedly, these issues can be mitigated with acetone wash, sanding and filling, and paint. But really, that's a lot more work than I wanted to do, especially for about two dozen small parts. The sintered nylon parts come smooth enough out of the "strong and flexible, polished" process, and are available in acceptable yellow and orange colors. The only issues are their porous nature and their matte finish, both of which are fixed by the urethane floor shine. (If you need PDP-11 or other colors, then you can probably substitute a suitable paint for the floor polish.) They do cost a little over $4 each, but that doesn't really seem that bad. Vince
