    Hello folks. I just read about the resolution differences between SLA and FDM and I read about the affects of resin out in sunlight or exposed to temps and how there are better resins for this. This thread has been helpful to the ill informed that way. But I can not get over the notion of using resin for a functional part. Nobody prints upgrade parts with their SLA printer. You will never see one of them self replicate. Resin makes very weak products that can sit on a shelf. But for strength I am pretty sure FDM is the better way. And also thicker layers and nozzle diameters make stronger parts. I am so sorry for this but that is the way it works. I'm not even sure if resin makes good things to use for molds to remake out of carbon fiber. To make parts to be used and handled on a regular basis and have screws sunk into it I am pretty sure FDM will find the better joy. I will never own or use an SLA printer because I exclusively make functional parts with 3d printing. Aside from the price jump for consumables and arguably much more important resin is weak sauce. That should be pointed out in this thread. That is the tradeoff for the resolution increase. An inherently weak but beautiful looking product that costs notably more to produce. I would argue that SLA printing is a large step away from 'rapid prototyping' But then I really don't care about perfecting a shelf trinket in a day.
