I have pretty much standard exposure settings.

Slice Thickness - 0.025
Exposure time per layer - 1500 (ms)
Bottom Layers Exposure time - 3500. no. of layers - 5
Lift and sequence time - 3900 ms

Here are a couple pictures of my latest metal cast from the MadeSolid .. CastSolid resin. I had a couple of unsuccessful attempts at making a decent metal cast until I found a formula for the investment.

I have the p1500 is mounted in the second hole. I am focused just fine, the lever is all the way over. I print at .25 mm just fine. Have you tried printing?

After trying several different cleaning times it has become evident that this is a very sensitive detail and the Madesolid website does not amply address this problem. What I have found out is that the models can only be left in the IPA for about 10 seconds or so and washed off with water for about ...

I am still trying to play with the CastSolid, but the B9 Casting Resin looks very promising! Thanks for sharing!
