It seems the the majority of the systems use fused deposition modeling would it be possible to create a home brew stereolithography apparatus? Or is the photo resin too cost prohibative?

I’m actually an avid wood worker so I know this is possible, I just dont know some of the nitpicky stuff.. I guess I should look into it more.. I very much would like to be able to output some models this way and even a course resin versus polyethylene or polypropylene would be fine to me.. I currently use a lot of polyester resin in one of my hobbies, but its too thin.. Not sure how to get it to thicken up a bit..

Where do you get your extrusion materials?

Thanks for this link.. I’ll keep it tuned in..

My own RepRap spinoff, Tommelise, is on track to cost about $150 for parts. So far it looks like I will be able to do 3D models in high density polyethylene (the plastic your cutting board and throwaway milk jugs are made of) and polypropylene (the plastic your coffee maker is made of).

Anybody with primitive woodworking skills should be able to bootstrap themselves into cheap 3D modeling with Tommelise.
