"This printer won't quite fit in your pocket, but it is very easy to take with you. I designed the printer around two constraints. First, the high mass motors and extruder are stationary. This allows smooth high speed printing, as only the print bed moves. This keeps the forces on the slides low as well. This will also allow dual extruders on a very lightweight printer. Second, the slides are all integrated, using PLA bearing surfaces running on the extrusions. It is self-contained, with power supply on board."
