I thought I’d post a little update on some printing problems I’ve been having.
I had a period of time where all my prints were failing dramatically. After talking with Formlabs support, we replaced my roller holder and LPU. I also replaced my resin trays. That markedly improved my prints. Small prints came out consistently very well.
But I continued having problems with big prints. Specifically, if the prints were located near the edges of the build platform, they would often have small missing features near those edges. I can often mitigate this problem by adding extra supports that protrude from the xy-extremeties of the object being printed. I don’t know why, but if there are supports just beyond the xy-profile of the primary object, I do not get failures.
Given that my warrantee is about to expire and this problem hasn’t been resolved, Formlabs is sending me a replacement printer. That gives me 90 days to work out the kinks and ensure the printer is running smoothly.
