You just need one of these UV flashlights to harden it, which only takes about 5 seconds under the light.

Not too shabby for FDM prints This stuff is a real game changer. The piece that looks wet was just coated and cured when I took this first pic. About 5 minutes of sanding and it's ready for primer. This stuff sands really easily.

I was wondering what you were going to do with the resin you got the other day. Now I know.

It's great. PLA prints like these are prone to cracking between the layers. I printed these at .100mm resolution, and they are actually pretty strong as is. But adding this resin helps bond the layers together, and gives the part a hard shell. Over 6 years I have been 3d printing, and I even had a laser SLA printer that used resin, and I never thought of trying this. It really is a game changer, because now my designs can lean a bit closer towards aesthetics vs durability, unlike before.
