Hi to all!
At the beginning of 2019, I received a bean 3D printer and had some great success printing some cups out of clear resin… A few months later I started printing again to run into an assortment of issues I can not seem to go around. My cups would develop holes and vertical stripes or cracks during the print process… I thought it was old resin, so I switched in between different bottles… not much change. I then ended up identifying that there were dark spots in the light quality during the print that resulted in absent details on the cup walls. I purchased a new screen and had some success… but after 20 hours of run time and 2 cups printed, I started experiencing similar dead zones seen with the last screen. Has anyone else experienced vertical voids propagating the whole length of an object?
My cups are fairly cylindrical…
I added relief holes to mitigate the suction that would blast holes in the walls. I also increased the wall thickness of the cups to avoid frail collapses of the walls.
How long are the screens supposed to last?
