Product Details
- 【High Heat Stability & Toughness】 – Polymaker HT-PLA Pro combines the durability and printing speed of PLA Pro with the heat stability of HT-PLA. Designed for functional parts exposed to elevated temperatures, it offers improved impact resistance compared with regular HT-PLA, making it suitable for electronics enclosures, automotive interior accessories, brackets, housings and functional prototypes.
- 【Strong Layer Adhesion】 – Engineered for demanding applications, HT-PLA Pro delivers strong flexural performance and improved layer-to-layer adhesion to help create durable functional prints. Its combination of toughness, rigidity and dimensional stability makes it a practical choice for custom fixtures, tool organizers, equipment accessories and everyday components that need reliable performance.
- 【PLA-Like Easy Printing】 – Enjoy the convenience of PLA-style printing without the need for an enclosed chamber or hardened nozzle. HT-PLA Pro features low warping, low odor and a consistent surface finish, making it suitable for most standard FDM 3D printers. Recommended settings: nozzle temperature 220–230°C and build plate temperature 60–65°C.
- 【High-Speed Printing up to 300mm/s】 – Designed for efficient printing, HT-PLA Pro supports speeds up to 300mm/s or a volumetric flow rate of 24mm³/s under recommended conditions. Consistent extrusion and dimensional stability help support repeatable results for functional prototypes, custom parts and print-farm production.
- 【Annealing & Printing Recommendations】 – For the best heat resistance, anneal printed parts at 100°C for 30 minutes. If the filament has absorbed moisture, dry it at 60°C for 6 hours before printing. HT-PLA Pro retains the basic UV resistance of PLA-class materials, so consider UV exposure when selecting it for outdoor applications. The reinforced cardboard spool is designed for smooth feeding and compatibility with most AMS and dry box systems.

Printing Polymaker PLA Pro
Polymaker PLA Pro in Green runs on the PLA Pro profile below, and this listing is a 1kg spool. PLA Pro is best suited to PLA parts that must survive heat after an annealing step. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our HT-PLA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.
