Make sure no one else is within three feet of the torch while it is lit. 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.
