This is a cool 3D UV Laser Printer, you can see lots of other details over at the Rob Hopeless site. It uses a UV laser to print items in a container of liquid UV-curable photopolymer. There is a platform that moves the item being printed down as the laser beam traces to solidify each layer in the polymer. The printed items look a bit gooey but this is an interesting printing process.

Thanks for the tip Andy.

“I have wanted a 3D Printer for a while now and there are some very reasonably priced kits available like the Makerbot, Ultimaker and the RepRap project. I could have just bought a kit and started printing things but at the time I had not seen great resolution or print quality from those. I started looking around at the other 3D printing technologies and found SLA made some amazing quality prints, so I decided to try making my own.“
