i was about to propose some sort of annealing process like they do with metals, and it seems like someone has already beaten me to it: http://3dprint.com/3388/study-how-to-make-3d-prints-stronger...

as a side note, this looks like kind of a cool way to smooth pla prints, for which up till now there wasn't really a great option.

that is a horrible article, considering the picture they are using is ripped off of a reprap blog on smoothing abs prints using acetone vapors. http://blog.reprap.org/2013/02/vapor-treating-abs-rp-parts.h.... (I'm actually a member of Fablocker, so I'd seen those squirrels before)

well shit. we tried putting some big pla prints in the oven last night and they definitely just started warping and caving.

on that note though, from my experiments, acetone vapor bath does seem to strengthen abs prints some, cause it melts the surface together. Not terribly big effect, but it actually helps a lot for low infill parts and stuff.
