I think we’ve all been there but do you know when you have a large cross-section as a base of a model and you attempt to print it horizontally flat on the bed (with supports)? That usually returns a mess of a surface due to peeling forces, nowhere for the resin to escape, etc.
I usually choose Rigid 4000 just because it’s very easy to scrape of those excesses of resin blobs and support marks.
I printed two parts, both with Rigid 4000 but on a Form 3 and an 3L.
One was a small prototype just to check for dimensions on a Form 3:
Which resulted in what was expected (a mess of a base):
The other part (which was a final part) was printed on a Form 3L:
What I didn’t expect was this super flat base surface especially being the part way larger than the other one:
The photos don’t show exactly how smooth it came out. It was dimensionally flat without a single bump, and even the where the supports touched I couldn’t feel any difference with my fingers. Sure, they’re visually there but not physically noticeable.
This was done with the “new” 0.05 beta setting for the Rigid 4000 on the 3L.
Has any of you ever got such a flat horizontally flat base before?
