RepRap: Blog

I've been having little luck using the fibre process to create objects in 3D Printer Resin. At best I get a few fragments. They're either falling apart when I drop IPA on them, or not sticking to the slide surface properly. I very carefully ran a print at 1μm/sec with a 4μm first layer, and the Nail Art resin stuck while the 3DP resin didn't.

The object was a 100μm diameter minimug, with an attempt at two layers on the wall. Either the walls washed away completely or never got created. Here's the surviving base together with what PrusaSlicer thinks should be there: 

I'm using an improved fibre holder rather than the zip ties for added stability (photo below, on the left). 

Now, it could be that I'm attempting layers that are too thin, or just moving too fast for the resin to cure, but that's for further experimentation. The takeaway so far is that Nail Art produces something and 3DP resin produces nothing so my material choice going forward is clear.

They are important factors though. If I'm using enough UV but not using it right, I won't need to wire up this fearsome array of 3W UV LEDS:

I think that might contravene local directed energy weapons treaties...
