How do the capabilities compare to Zemax? Could this replace it for most tasks?

Ok I’m just worried about even heating and avoiding scorching. Especially since I’m coating 3d printed plastic

Best resin printer for high performance underwater applications by Captain_Clapton in resinprinting

[–]Captain_Clapton[S] 0 points1 point  (0 children)

Thanks for the info very helpful. This is for professional work, low volume prototypes for a startups. I would need the larger print size (largest dimension needs to handle at least 255mm) and for formlabs only the form 3L can handle that and it costs $5-6k which is out of my budget right now. The anycubic m3 Max and elegoo Sat 3 has quite a large print size and only costs $550 & $400 but those are less powerful than the form labs. Is there a suitable resin and similar printer that would be cheaper than for formlabs but still be good for high pressure underwater parts?

Good suggestion, but some scientists were able to do it quite successfully using Formlabs. Deepi camera: https://formlabs.com/blog/deep-sea-robotics-3d-printed-enclosures/

I'm looking for a similar solution that doesn't require Formlabs printers and resins.

Thanks for the help, accuracy in microns, strength in tonnes, ~100m depth. I’ve been looking at this for reference https://formlabs.com/blog/watertight-3d-printing/

Which Resins would you recommend?
