Spotted in the MAKE Flickr Pool, John Biehler’s excellent photo of a tiny prototype fused-filament 3D printer designed and built by Fraser Valley RepRap User Group member “Brad,” aka Sublime. Brad’s posted a detailed description on one of his personal blogs and on the RepRap wiki, but hasn’t published the physibles yet. The “vitamins” ( non-printable parts) consist of four stepper motors, eleven skate bearings, ten linear bearings, a couple pieces of smooth and threaded rod, assembly screws, and the standard RepRap electronics. The build volume is just a bit over one cubic decimeter. He calls it “Tantillus.”
