Has anyone surface epoxied PLA and or annealed it to strengthen it?
Man, I keep finding stuff in this thread to reply to. I have annealed protopasta's ht PLA and polymakers pla pro. Just gotta be careful with the temp not to warp it. Having access to a calibrated lab oven helps alot with that. Take it off the printer still attached to the bed (glass bed clipped on is best for this). You can get the same result to a lesser degree just buy running a butane pen torch over the whole part carefully.
