This is the real deal, no derivatives here. These are the real Printrbot in it’s current version. I have a bunch of these printing all day, every day…. it works. It is expandable to larger widths and heights easier than any other reprap out there. Period. Its the most inexpensive bot out there being mass produced. And, its now yours to print, build, improve, change…. whatever you like. I can’t wait to see what you do with it. I will post pics of all the various forms it takes, news, etc at printrbot.com
On a related note, Brian at HaD has been rocking out lately, great posts.
