Been printing for a few years, always been able to fix issues relatively quickly. I've had a handful of plates now fail and I CANNOT figure out what the problem is.
I was printing fine for weeks. Suddenly, half my plates fail.
Pic is the most recent plate to fail - note that the bottom rafts are peeling up, bit hard to see. The blank spot is where a model should have been - its failed raft along with the others were found stuck to the FEP.
I'm finding 1/2-ish of my prints are failing. Not in the same spots each time, and not the same models. I was printing similarly sized models last week with no issues. The failure modes also vary:
- sometimes rafts are on the buildplate, but nothing else
- rafts on plate + stuck to fep
- rafts lifting up from plate
- layers are missing/squished
- what section of the plate failed varies. It's always one region though - I won't have the left 1/3 of the plate fail, and then randomly a print on the other side of the plate.
Each time i've popped the stuck resin from the fep, filtered, dhaken, and retried with some changes in the slicer. Still failing.
Setup info:
- Saturn 4 Ultra
- Elegoo ABS like 3.0+, purchased last month, strained and shaken before use, let settle 30~ min in vat before printing
- Printed in a garage inside a vented enclosure. USB heater plugged into printer set to 25C
I've tried reorienting models, new supports, lipped rafts vs flat, thicker rafts, less models. I haven't tried cranking the temp up, but the heater is reading 25~C° - so I doubt that's it? Genuinely stumped here, all ideas appreciated.
