-A process of improving strength of plastics. PLA / PLA+ is generally considered to be impractical to anneal for most frames due to warpage and shrinkage. Although there has been anecdotal accounts of packing frames into salt / sand during the heat annealing process which had minimized annealing.
+A process of altering the mechanical properties of plastics by heating them over their glass transition temperature and allowing to slowly cool down.
+Annealing can have different effects on different polymers. In case of the polyamide family, [https://odysee.com/@hoffmantactical:3/annealing-nylon-prints-to-solve-creep:e according to tests ran by Hoffman Tactical], it makes the plastic less prone to creep. In case of PLA, it facilitates recrystallization, raising the tensile strength a bit and the temperature resistance to a great degree. In the general case it relieves the internal stresses introduced during extrusion, which leads to warpage and shrinkage.
