The annealing process\n  causes 1–2% part shrinkage, so parts that require tight dimensional\n  accuracy should be modeled with this allowance, and constrained in a\n  gypsum or salt flour mold during the anneal to control warping.\n  For parts where dimensional accuracy is secondary to thermal and\n  mechanical performance — brackets, housings, structural components —\n  annealing delivers performance that is difficult to achieve in any\n  other PLA-based material.\n\u003c\/p\u003e\n\n\u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n\u003cp\u003e\n  Tough Pro PLA+ is the right choice when standard PLA has failed you —\n  parts that cracked under load, deformed in a hot car, or broke on\n  impact.
