#3DBenchy printed at 100micron XYZ resolution on my @Kudo3D Titan 1 SLA DLP printer. This is the lowest resolution mode of the printer (which is adjustable from 37 microns XY to 100 microns XY (5 to 100 microns Z). This was printed flat and completely without supports. The only finishing I did was rinsing and some UV curing.
The overhang of the roof of the cabin came in very well, and the surface finish on the underside of the room (which is unfortunately hard to see in the picture) is quite good. The stair stepping and pixel artifacts are interesting when printed at “low” resolution.
I also made a few videos of what the software toolchain and printing process look like: 3DBenchy - YouTube
@Whosa_whatsis You have a good eye. There are two black benchies, one that’s flat-topped and one that’s wavy topped.
The flat topped one was printed with the stock vat that Kudo3D sells, which is 5mil FEP film on top of very soft silicone.
The wavy topped one is from a vat that I retrofitted with 2 mil TPX film. The thinner film doesn’t pull the silicone back flat after each lift sequence, leaving a wavy texture at the top.
On the black one, I think the bulge halfway up is mostly shrinkage. Since I did not hollow out the model, the shrinkage of the solid mass creates a visible seam on the exterior wall. The bulge is right at the level of the deck and the overall Z height is spot on.
For the red one, there is a seam about 75% of the way up and the overall Z height is a little short. I think that’s a skipped step because of some USB connection problem to the RAMPS that controls the Z axis; I have a hub that seems to have started acting up now that the weather’s become warmer.
