Rafi – A Stereolithography Printer with RepRap Printed Parts
By Eran Rom
The major difference brought with this design is the usage of PLA printed parts instead of the aluminum parts used in the original design. While at it I tried to somewhat improve the design here and there.There are still many improvements that can be done. In particular I am working on a way to fix the iris in various opening diameters. As with the original design I have used plywood for the case, and am using the exact same electronics (although I have had better experience with Nema motors and Pololu based stepper drivers).All parts sources can be found on GitHub: https://github.com/eranr/rafiThe instructions appear on the GitHup repo wiki: https://github.com/eranr/rafi/wikiA word of caution: Other than being careful when dealing with the laser, operate the printer in a HIGHLY ventilated room, the resin is an industrial stuff whose fumes you do not want to inhale. I would be happy to hear about more home friendly materials that can be used.
