Need PLA that handles more heat without jumping straight to ABS? Polymaker HT-PLA is a heat-stable PLA that prints on most FDM machines with PLA-like settings. Polymaker rates heat stability up to 150°C under the part’s own weight. For parts that carry load in heat, anneal after printing.
What's Included
- 1.75 mm Polymaker HT-PLA
- About 1 kg net on a cardboard spool (AMS-friendly edge design per Polymaker)
- 14 colours: Black, White, Grey, Blue, Red, Green, Yellow, Orange, Brown, Teal, plus Rainbow, Tropical, Ice, and Fire gradients
Print Settings
- Nozzle: 210–230°C
- Bed: 25–60°C
- Printing speed: up to 300 mm/s
- Fan: ON
- Retraction: 1–3 mm at 20–40 mm/s (direct or Bowden starting points)
- Drying (only if moist): 60°C for 6 hours
- Enclosure: not required
For higher temperature stability and better HDT under load, anneal about 30 minutes at 80–100°C (100°C recommended). Let thicker parts cool in the oven when you can. Polymaker notes as-printed HDT is about 58°C (1.8 MPa); annealing raises heat performance for loaded parts.
Material
PLA-based multiphase composite (main structure is PLA). NatureWorks-based resin per Polymaker FAQ. Density about 1.29 g/cm³. Vicat softening about 156°C. Non-abrasive (unlike HT-PLA-GF).

Need more stiffness and fibre reinforcement? See Polymaker HT-PLA-GF (separate SKU, abrasive, hardened nozzle). HT-PLA is the easy-print, non-filled heat-stable option.
Good To Know
- Heat stability “up to 150°C” is under the part’s own weight. Under load, expect behaviour closer to the as-printed HDT until you anneal
- Still a PLA family material. Not a drop-in for every ABS/ASA job
- Layer adhesion is fair; avoid fragile single-wall parts for heat-critical jobs
- UV / weather resistance is similar to generic PLA (Polymaker)
- Dry if the material has absorbed moisture
Good For
- Warm-environment prints that still want PLA ease
- Fixtures, jigs, and functional parts that see heat
- Prototypes that must survive a hot car or sunny shelf better than standard PLA (anneal when you need higher heat under load)
- Cosplay and props that need colour plus better heat hold after anneal
