DIY 3D printer utilizes hot air, sugar to craft random objects
Just when you thought a $5,000 3D printer wasn't such a bad deal after all, the zany gurus at the Evil Mad Scientist Laboratories have put Desktop Factory's iteration to shame. The CandyFab 4000 is a homegrown printer that utilized a bevy of miscellaneous spare parts around the lab as well as the same sort of CNC hot-air control mechanism that we previously saw in the text writing toaster contraption. Their selective hot air sintering and melting (SHASAM) method allows the printer to begin with a bed of granular media (sugar, in this case) in which a directed, low-velocity beam of hit air can be used to fuse together certain areas repeatedly, eventually working the remaining grains into a three-dimensional object. The creators claim that while their CandyFab machine only ran them $500 in addition to junk parts and manual labor, even starting from scratch shouldn't demand more than a grand or so, so be sure to click on through for a few snaps of the fascinating results and hit the read link for the full-blown skinny.[Via MetaFilter]
