It looks like I got a tear in my FEP and resin leaked onto the screen. Looks like it is damaged. I see a replacement for $90 on the website. It was purchased on 3/30/26. What are the recommendations? Reading Phrozen’s warranty info I doubt if it is covered. Should I try to clean it? Should I order a new screen and try to install it? Should I buy a new printer?
I’m printing miniature components for a book nook and could use some help troubleshooting recent failures.
My setup:
Printer: Phrozen Sonic Mini 8K S
Resin: Phrozen Aqua 8K Grey
Slicer: Lychee
Layer height: 30 microns
Normal exposure: 1.9 seconds
Wait before print: 2 seconds
Heated enclosure
temp remained between 77 and 81F
I recently had a smaller miniature print come out clean and square with these settings, but my latest job with two larger pieces failed. One was a tall rectangular control-panel back, and the other was a galley cabinet. The galley was printed solid and was fairly heavy. The control-panel back failed in a similar area. I retried with just the control panel last night and it failed in a similar spot and way.
There was plenty of resin remaining—the vat was full when I started.
I’m attaching photos of the failed pieces, their orientation/supports, and my settings. I’m trying to figure out whether the main issue is:
Too much cross-sectional area or peel force
Orientation or insufficient supports
Printing the galley solid
Exposure or lift settings
A possible FEP or screen issue
Would you start by printing the control-panel back alone with a different orientation/support layout? For a tall rectangular piece, would you orient its long dimension more horizontally or vertically, with an appropriate tilt?
I’d appreciate suggestions on what to change first so I can troubleshoot systematically. Thanks!
