Hi everyone, I finally got my moai calibrated and printing after a week or so of struggling. Turns out I didn’t have any leveling issues, but rather a thin layer of dust that had gathered on the galvo protector glass. Don’t build your printer in dusty places!
Anyhow, I had a question about how much supports are needed for scaling up a model. I tried two test prints (there were the upper body of a figurine I had previously printed) after I had finished all of my calibration. Both of them were oriented the same, and were the same model. The only difference was that the first was scaled to one inch, while the other was scaled to four. The smaller print came out successfully and looks beautiful (even those tiny fingers printed successfully!). However, the larger print failed completely with only some of the supports ending up on the build plate. Both models were sliced on the latest version of Asura, and with the default support settings. I did hollow out the model and add holes, but it didn’t even get that far so I don’t think that was the issue. The only extra bits I did was add a few extra supports where it seemed like the software missed a few overhangs. Am I correct in assuming that my failure on the larger model is due to a lack of support structures? If so, what kind of support density should I be aiming for on those larger models? (default is 5mm spacing with 2mm thickness i think…)
I am printing on the FEP vat with peoply clear resin. Door is sealed and chamber is heated. I am aware that the FEP vat requires thicker and more numerous supports, but I couldn’t find a number to go off of. I also slowed the PM motor speed down to 10. Thanks in advance!
