Build Your Own SLA/SLS

In these points between the settings there should be a void and instead they are closed, at the bottom you can see that the surface of the ring is rough.

I'm continuing with the tests, but there continues to be a problem of bleeding on all the prints in the side facing the construction plate, if I decrease the exposure time many small details do not get well and the problem remains. I use resin FTD RED Castable, Acer H6510BD projector, distance 50 mi...

Today I added another resin bringing the level to 3 cm. I tried to reprint the ring with the gecko but it came like yesterday's. Then I tried with this twisted pendant (2h and 20 min - 5.3 cm.) It came fairly well as it did not have large walls like in a ring, but the problem of roughness always in ...

The ring with the gecko on half of the circumference is wrinkled and the other half a part is wrinkled and the up...

These are the photos of the printer.

I enclose the first photos of the tests with the 31mm model. x 21mm x 10mm. all performed at 50 microns with exposure that goes from 3 sec. at 1.85 sec.e waiting between one slice and another of 10sec. We still have to work a bit on the times and other things but there are almost. Processing time ab...
