After running a day or two of tests, I'm trying to print my first action figure using a roughly 50/50% mix of Siraya Tech flexible "Tenacious" resin and regular black.
It's a bit disappointing that I have to use such a high ratio because (A) the Siraya stuff is super expensive and (B) it makes smaller parts semi-transparent, but the degree of flexibility is inversely proportional to the thickness of the part, which makes perfect sense.
I noted on my test prints that the tiny 1.5mm support columns become semi-flexible (like the teeth of a comb) at about 33% Siraya but the 13mm wide part I was trying to print was still completely solid. At 50% Siraya, the 13mm tube is still utterly inflexible, but I've got a tiny amount of bend on the 3mm raft, and the 1.5mm support pieces bend easily with something close to the flexibility of most fingers and small accessories on vinyl action figures (though they will snap and break off if you bend them too far).
50/50% is probably the best mixture I'm likely to get without also having parts that are completely see-through. (I've learned that flexible = unpaintable, so what you see is what you get.) I may get slightly better opacity results with resins that aren't black, since it's semi-translucent to begin with. I'm curious as to what this stuff will look like mixed with Anycubic Flesh.
I've had to adapt my usual FDM printing plug design to incorporate a U-shaped hole in the center that I hope will give the two prongs enough flex to fit into the sockets and then elasticize back into place so they don't pop out again after assembly.
Assuming no misprints, I should know by tomorrow morning if it's worked.
