Cheap, portable personal 3D printer: the UP!

The UP! personal 3D printer from China retails for $1500, with goop running at $50/kg. From this early adopter's review: It runs at 0.3mm resolution, and the finished models show striations from successive layers of goop, but light sanding produces a smooth finish. For objects with funny extrusions and sitcky-outie bits that aren't stable until they are fully printed, the printer calculates and adds support struts on the fly, and these have to be removed with a hobby knife after printing.
