Karen sez, "Instructables user RobHopeless has engineered a way to make your own 3D printer. This tutorial is an entry in Instructables' 4th Epilog Challenge, which is accepting all sorts of creative projects for the chance to win an Epilog Laser."
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. Since I started this a while back those projects have come a long way and they can make some beautiful prints now. There are also people working on a UV resin and DLP projector 3D printer which is showing promise.
