The $1,500 closed-source UP! Personal Portable 3D Printer (PP3DP) does its thing, putting the heat on open alternatives like the Mendel and MakerBot.
We have been developing the UP! printer for more than one year, it is completely based on our own efforts, we have not used open-source solutions for this design. We understand and follow the RepRap and Fab@home projects with great interest, however these designs follow a quite different direction than we have chose for the UP! printer development.
