Evil Mad Scientist Laboratories just released a new version of their sugar 3D printer, the CandyFab 6000. It’s smaller than previous models, enough so to fit on a tabletop, but still has an impressive 10 liter build volume. From the site:
Here’s one of the first objects that we fabbed on the CandyFab 6000: a drilled sphere, about two inches in diameter and layer thickness of 1/15 inch. There’s plenty of room for improvement, and finally we have a machine that can be improved.
The machine is designed so that it can be made from scratch– i.e., without dumpster diving for old HP pen plotters. Three axes of quadrature-encoded DC servo motor control. Timing belts and acme lead screws. Food-safe sugar containment. The body is made from laser-cut plywood with acrylic highlights and stainless steel hardware. (Steampunk-compliant brass thumbscrews where appropriate, too.)
