Heat Ready. Impact Ready. Still PLA
Polymaker™ HT-PLA Pro is a tough PLA for functional parts that need better durability in real-world use. It prints as easily as standard PLA and keeps its shape without load in warm environments. It is made for makers, engineers, and print farms that need real durability without added printing complexity.
Won't sag up to 150°C straight off the plate
Polymaker™ HT-PLA Pro is designed to keep its shape in heat-exposed environments without load. Its Vicat softening temperature reaches 148.3 °C straight off the build plate and 150.5 °C after annealing, tested off the plate with no load. For applications that require heat resistance under load, annealing is needed. A 30-minute anneal at 100°C increases the Heat Deflection Temperature (HDT @ 0.45 MPa) from 56.3°C to 107.6°C. This makes it better suited for warm-use cases such as sunlit windowsills or parts placed near heat-emitting machinery.
2x PLA durability
HT-PLA Pro keeps strong thermal properties while improving mechanical performance. Compared with regular HT-PLA, it delivers more than 2x higher impact strength (9.94 kJ/m² vs 4.94 kJ/m²) and 30% higher Z-axis interlayer adhesion (26.8 MPa vs 20.8 MPa). This helps printed parts resist impact and splitting along layer lines.
Prints with PLA settings
Unlike many high-temperature filaments, HT-PLA Pro prints with standard PLA settings. It runs on most standard FDM printers, with no enclosure, no specialty hotend, and no complex tuning required. Supporting print speeds up to 300 mm/s, it can fit into existing production workflows with minimal changes.
Please note: Annealing is required for heat resistance under load
