Managed to do a quick test print (grey resin) before packing for trip…
Impressions so far:
-
the surfaces are indeed smoother than on Form2; edges are nice and sharp - you could scratch or maybe even cut yourself on an acute-angled edge of a printed object with no fillet
-
that said, the new LFS peel isn’t magic - you’ll still get layer lines and artifacts on thicker cross sections, as well as the usual odd surface artifact
-
technical prints can still get slightly deformed, straight lines can still get curved, right angles can still end up oblique instead of right
-
that said, you can get away with less support than before, and less forethought - i printed a few relatively tiny parts, but non-hollow, with 0 preparation and thinking, using the automatic layout and support, with supports reduced to 0.4mm, density 0.8, layer height 100um; I normally use those settings on Form2 for hollow objects with a 1mm thick shell, and i normally lay things out carefully by hand
-
supports are still the same, their geometry is exactly the same as Form2’s, meaning you’ll still get warts on your prints - again, it’s not magic, it’s just an improvement over the previous process
-
curiously, i got some layering artifacts where i normally wouldn’t expect them on a Form2 print (namely, at the very last layers of a (fairly short) object, where the cross section starts to get smaller, not larger
I took some quick snaps with my phone, I’ll try to post them later, probably from the airport.
Edit: I hope the new vats are more resilient to resin, as i’m leaving the resin inside it for 2 weeks until i get back. On Form2 i’d usually empty it back into the cartridge or into a jar, as the resin would inevitably eat and delaminate the PDMS, sometimes in as little as 3 weeks or so.
