Step 14: Wrap up
As for cost of building the machine, I think I spent about $600 - $800 for everything. Less than the extruder printers but the material cost is about 4-5 times more so it's not really the economy option.
There are also other ways to print with UV cured resins, like using a DLP projector to show images for long enough to cure a layer. There is one person that has made one that seems to work well but it looks like it is closed source and going to be expensive when he starts selling it. There is also a Yahoo group called diy_3d_printing_and_fabrication with people sharing their DLP based builds and resin tests.
You should have used a laser galvanometer (galvo)! Sounds great, if you find one accurate enough for under a few hundred dollars let me know!
Just for fun, the picture above shows most of the bad prints I've made so far.
I probably missed something so let me know if you have questions and I will get to them as soon as I can. Thanks for reading.
