Re: Tips for fixing warping and delamination in 3D printing?

My dad and I had reasonable success (with PLA) dialing DOWN the print bed temperature a bit. I think we were running 60 C while the "standard" was 70 C. We were also running a very "cool" print tip, 5 C above the PLA melt point (default was something like 15 C higher than that).

Again, this is for PLA, but I think it's a plausible solution for warping.


For parts coming off the plate, we found that often that was the plate surface-- moving the print location tended to help out. (We think the Kapton was starting to wear out a bit.) Also, that's a problem when parts are warped more than when they aren't; fixing the warping should help. (Again, this is PLA parts, not ABS, but the theory may transfer.)
