I thought I had seen a few related project threads here over the last few years, but I can't seem to find them any longer.
Have been playing around with prototyping some equipment to make working with film projects a little easier for me, but have been hitting a gap on clear info with regards to 3D printing and photo chemistry.
I'll admit that my knowledge of chemistry is probably in that fun space of 'knowing more than enough to walk into problems, with confidence', but I'm fairly confident that the typical black and white chemistry will be fine when in contact with typical quality PLA plastics, and a few small scale tests have shown no issues.
Less clear is whether or not C41 and E6 chemistry is going to play as nice.
Not planning to use any of this to store chemistry long term, just for active development sessions.
Any better chemists than myself familiar with 3D printing materials and their safety with a wider range of photo chemistry?
I suspect that the biggest risk is really any added pigment more so than the base PLA itself.
Switching to the less common HDPE is also an option for most 3D printers [And would put a more comfortable space between C41's working temp and PLA's max working temp], but I would rather stick with the easier and more common plastic if it can be expected to work 'good enough'.
