The first one I tried was the Spot-a GP. The Spot-a cures much faster (about 1/2 the time) but it was clear and I had to add my own pigments (cast'n craft). It was also more expensive and shipped from spain so the shipping cost was significant. I used this resin for my first test prints and was very pleased with the results. I pigmented it with a mix of Cast'n Craft black and white opaque pigments to get a greyish resin (similar to the Form1 resin). My cure time was 2.6 seconds for a 0.1mm layer (actualy 0.15 cure depth). I noticed the pigment didn't stay suspended very long. It wasn't a problem for my testing, the longest print was about 40 min. But I think it could be a problem for sessions of 2 or more hours without some way to agitate the resin.
Next up I tried The MakerJuice. It comes pre pigmented in a range of colors. It is significantly less expensive and ships from the US so the shipping was cheap and fast. The downside is that the SubG+ shrinks a bit more than the Spot-a (Hopefully Josh @ MakerJuice will keep refining his formua and release a new resin with even less shrinkage). I't's not a deal breaker but something to be aware of. The other thing I noticed is that the resin is somewhat translucent. That makes it dificult to see or photograph details without a coat of primer. I think I'll try adding a little more opaque pigment to tone down the flourescent tangerine color and cut the translucency.Statistics: Posted by 258cj7 — Tue Jan 07, 2014 4:59 pm
