I’ve had an Elegoo Mars for about a year and generally I’m pretty happy with it. I’ve now got to a point where I am starting a low volume business that only requires one or two prints a day, all of which comfortably fit on the build plate of the Mars. However, quality is key as the finished items, after post production and electroplating, sell for $300 - $500 a piece. Is it worth upgrading to a refurbished Form2 or a brand new Form3? What I print has relatively complex geometry and even with very precise supports and orientation I would estimate it fails 25% of the time on the Mars. So far I’ve had to replace 3 screens and 8 or so FEPs on the Mars, which although they aren’t expensive can be a pain.
TLDR: is upgrading from a Mars to a Form2 or Form3 worth it and if so, is the 3 worth the extra cash?
