I'm trying to print this container with a Voronoi pattern on it. The actual object itself was created using a combination of this online tool and Fusion 360. This was then imported into Chitubox (V1.7.0), rotated by 20°, and auto supports were generated (default medium weight, 60 % density). This was sliced and then exported as a .cbddlp file, stuck on a micro SD (not SDHC) card, and printed from there.
I'm using a 'MonoPrice MP Mini SLA' resin printer, along with Elegoo standard blue resin. The print shown in the pictures below was printed in a warm room (probably ~20 °C), the print bed had been cleaned prior to printing with isopropyl alcohol, and the vat/FEP with warm soapy water; both were left to dry fully.
- Bottom layer curing time: 120 s
- Other layer curing time: 10 s
- Bottom Layer count: 20
- Transition layer count: 20
- Light off delay: 1 s
The vat/FEP film was tightened down nicely, the print bed auto-levels before every print.
'Simply', why have I got these random holes appearing? I have never had a single issue with the bottom layers not adhering properly, but now I have these holes that are completely surrounded by perfectly acceptable print. Is it something obviously wrong with the model/supports (too complex/flimsy)? Is it slicer related (just not generating print data for those areas)? Settings related (over/under-exposing)? FEP related (too sticky/not tensioned correctly)?
No random gaps.
