Annealing prints has been something I’ve wanting to do more of, probably with proper temperature control as my experience has has more waste than I’d like, mainly warping.

Paper claims some pretty dramatic improvements to interlayer strength, they’re running filament through a bath before entering the extruder, not sure how accessible the entire thing would be in a hobbyist environment (using chloroform and specialised microwave equipment). Makes me wonder however if carbon fibre filaments would be able to be processed similarly, how well it’d perform with stuff like abs or nylon and if you could achieve that with consumer microwaves.
