This link came in the mailbag from one Junior Veloso, of Singapore, who has produced this very impressive homemade photopolymer-based 3D printer. Traditional stereolithography uses a scanning UV laser to cure the liquid resin, one layer at a time. A DLP printer is similar, but uses a micromirror-based video projector to expose each layer, as shown in the diagram. Junior’s version exposes each layer for four to eight seconds, resulting in print times on the order of several hours. The resin has to be opaque to prevent “shadowing” from light transmitted through the printing layer. [Thanks, Junior!]

this looks like a very nice upside down version of this 3D printer developed at the University of Illinois.

The chemicals only cost a little over $100 due to the amounts their sold in, but is very easy to setup and get running. I first saw this at the 2009 National NSTA Conference where they printed a nano chess board in 5 minutes.
Their automated process that works off a 3D computer model must make the preparation process incredibly faster.
Amazing!

what is program for interface ?

I’d Like to make one too. But While I do have a spare Laptop to use, I don’t have a projector. Pico Projectors are small and inexpensive. Here is a Like to one on ebay http://cgi.ebay.com/Optoma-Pico-PK101-DLP-LED-Pocket-Projector-/350484151663?pt=LH_DefaultDomain_0&hash=item519a7bbd6f
Sean do you think this will have the resolution to crisp enough edges on the Models?
Nice Article ,thanks!

I would really like to read the blog you referred to, but unluckily it’s only visible to chosen readers :(
And yes, I know how old this article actually is ;)
