It’s finally here ! You can make your own pre-prototype right at home. MakerBot Replicator Mini Replicator3D printer. An early version last year had glitches that supposedly were dealt with in its’ latest version. It still remains small and is fairly slow–on the plus size is its’ ease of set-up and the user’s ability to monitor its’ printing progress.
MarkdownMom found prices ranged from a low of $600 on Ebay to a high of $1400. Still a rather expensive novelty–you may want to wait for technology to catch up to its’ potential.
