Comment on Issues with my second resin print
CaptainFlintlockFinn@lemmy.ca 9 months ago
I started resin printing a couple months ago. I had some of those layer problems too. I found that I need way more supports than I thought I needed at the beginning. This is a pretty good guide on supoorts. Alternately Ive been using lychee slicer’s auto supports. They seem to work well for the most part.
I also just recently did some exposure tests. It takes a while because each test is about 20 minutes but it turns out I was under exposing my prints so things are better now.
Lastly I replaced the usb stick the printer came with. I highly recommend doing this right away, a bad stick can do weird things. I got two 64gb Kingston data travellers for $10 Canadian. It’s well worth it.
Haven’t had the layer issues since I did these things and, fingers crossed, I haven’t had a failed print since either.

Thanks for the recommendations!
A new USB is definitely on my list of things to get…I honestly forgot about that recommendation how it can cause weird issues, but that’s a good point to rule out.
I tried adding some new supports on another attempt last night but had some issues with the print seemingly not printing at all, or maybe it was and I was impatient. Going to try again tonight after watching this video, thank you for the tips!

Any time!
If it didn’t print at all I’d be looking at that USB right away. I had many half printed things and corrupted files before I clued in.

I’m unsure as it said it was 73% done but I saw supports and not enough actually printing under the supports…it was weird. But when I went to clean everything, there was a huge circular piece of plastic in the bottom of the vat. So I’m so confused lol
But you’re right! I’m starting from scratch today with deep cleaning on everything and recalibrating. A new USB would be perfect to match!

That piece on the FEP sheet is where it let go from the supports when the build plate lifted. More support will probably fix that.
I always think about what’s happening when I’m doing supports. The resin gets cured on the FEP then the build plate moves up and pulls that layer off the FEP. The part is being pulled by forces in opposite directions so we need to make sure that the part hanging on to the build plate is sufficiently anchored so it’ll pop off the FEP and not off the build plate.
