Nice! I donated my first-gen Makerbot to a maker lab. Now I'm shopping around for a new printer.
I want a heated bed, auto leveling and an extruder that can handle higher temps. Creality is of course on the short list. I'm leaning toward Prusa. More expensive - but all the features I want.
Any thoughts on resin vs. PLA or ABS? My gut is telling me Nylon is the way to go for a frame. You need a hot extruder for that but I think it may be worth it.
I'm also in the market for a printer and have pretty much decided on a Prusa machine based on my association with a local business that uses them exclusively to make short run products.
With no experience ... I feel like a carbon-fiber polycarbonate (PC) would be the best fiber for frames. Requires a hot extruder, hot bed and hardened steel extruder tips (Prusa !). PC is very impact resistant and creates high(er) strength parts especially with carbon-fiber addition. Also very stable at higher temperatures (use temps).
My thoughts are that PLA is marginal for frames, especially at somewhat higher use temps, but fine for many other parts. Obviously PLA has been used for this, but my tendency is to over-build

everything I create.
