Recently I tried some photopolymer from http://www.druckwege.com (Germany) - which was said to be compatible with the B9Creator. Since that resin is transparent, it cured not only within the actual but also several layers above, ruining the entire geometry
I guess one has to increase opacity as it is the case with the B9R-1 red (obviously, red particles in it since these settle at the bottom of the bottle) or MakerJuice black I used before.
I successfully coloured some of this transparent resin using a dye meant for acrylic casting but it was still transparent then and allowed too much light to travel too far again.
Has anyone here ever pigmented a transparent photopolymer of the polyetheracrylate type to avoid over-curing in z direction?
