However in some cases, an undesirable phenomenon may occur during recrystallisation annealing. Like all things in reloading consistency is the key. For small parts,the hotplate is a good idea. It is nearly always best to anneal in sequential areas, rather than trying to “heat the whole thing”. Full annealing is performed by heating to a temperature between 760 and 830 °C for 90 minutes per 25 mm of thickness, followed by air quenching. Annealing works by getting the plastic to a hot enough temperature to allow its amorphous structure to change and morph into a much stronger, crystalline structure, but this sort of “reorienting and repositioning” of the crystals will cause the printed part to shrink and grow slightly. Hi there! Only thing to beware of is the cool spot in the centre of the hob which will result in buckling if you leave part of the brass over the cool centre but re-heating the buckled part over the hot part sorted it out.
