Print problem resolved

Postby jon_bondy » Sun Apr 03, 2016 5:38 am

I was having problems printing Vorex on the LittleRP. There were two symptoms: very rough surfaces (with little spikes sticking out) and soft "gunk" all over the print. Turns out that the front surface of the projector lens was dirty, as was the mirror. Both looked OK when inspected casually, but the prints improved dramatically after really cleaning the front surface of the projector lens, and replacing the mirror. My theory is that the light was getting spread just enough that parts of the print that were not supposed to cure became partially cured, thus the "gunk" and spikes.

Interesting conclusion! I'll have to keep that one in mind. Thanks for posting. :)

I have loads of FDM failed prints but no SLA failures.
