A few weeks ago, I found that every print I attempted would fail at a certain point, and cured resin would build up on my PDMS.
I clean the build platform and rake the resin tray after every build.
I noticed no potential issues except for possible clouding on the PDMS. I ordered 2 new trays.
When I received the new trays, I opened a fresh bottle of resin and poured it into the new tray. Same problem occurred as it did with the old tray. See pics:
Notice the left and right failed objects. This is how they appear in preform:
Notice how the taller object sort of “cut off” at the slant? This is what’s happened every time. It’s happened with every object I print, not just these. Also, i’ve successfully printed several of the now-failing objects before… so I know the .stl files are good and the orientation/support is good.
Lower objects seem to come out ok. I attribute this more to time than to height…ie - the slow buildup of hardened resin on the PDMS.
Also, notice the “skin-like” buildup? That’s new to me with the Formlabs white resin, and with the new build tray.
I saw on a previous thread that someone thought maybe the new firmware had a laser power issue causing this?
I can’t print without a failure, or without buildup on my PDMS - please help. Any ideas?
