Inlay is going to turn into a saga If this keeps up! I had previously tried doing my own alternative to inlace’s resin infill material. It was kind of a disaster. The dye I added had a very adverse effect on the two part epoxy and resin. A few weeks later I looked at the casting dye and noticed that it had completely separated. There are no instructions on the bottle to mix before use, so it isn’t 100% my fault. I remember last time that I had to add a lot of the stuff to color the resin, and It still wasn’t very opaque. That could have been my issue all along.
I created another test structure and went to work. I don’t need to revisit inlace, I know it is good. For the acrylic paint, I tried to slop it on really thick so when it shrinks the pockets will still be filled. The two part and polyester resin were done with a minimum amount of dye added. This time they looked proper dark. The results were unfortunately bad. The polyester resin didn’t adhere well, and the two part epoxy had kind of a rubbery feel to it.
Well acrylic it is then! I went a little deep with the sanding and buzzed off part of the R, but other than that It looks good. Without further thought I ran off to make the “Cube Sweet Cube” sings I wanted to make weeks ago. The results were not issue free.
The acrylic paint shrinks considerably when it dries. The shrinkage is difficult to predict and often includes bubbles. I was trying to go thin on the pocket milling so I didn’t have to use as much paint. In trying to plane everything flat I shaved the paint right off in sections. The neat byproduct of that is some really cool looking shavings.
I have one last test up my sleeve. The acrylic paint coats well, but does not build up consistently. I will try taking a rounded bit and make deep pockets. These will get a good but thin coating of paint. I can shave or sand plenty off the top with out worrying about going too deep. Assuming the surface finish of the paint is ok, this should be a good solution. More results to follow!
