About

High Temperature PLA Filament for Heat-Resistant 3D Prints Polymaker™ High Temperature PLA filament gives you PLA's easy, reliable printability with far better heat stability for functional parts. Choose from HT-PLA, HT-PLA Pro, and HT-PLA-GF to create tools, fixtures, enclosures, cosplay parts, automotive accessories, and other prints that need to retain their shape in warm or heat-exposed environments. Unlike regular PLA, these advanced PLA materials are designed for higher thermal performance. HT-PLA and HT-PLA Pro offer excellent shape retention in heat-exposed conditions without load, while HT-PLA-GF is the best option when your application needs improved heat deflection performance under load after annealing.
