Polymaker HT-PLA Pro and the Panchroma Rebrand: Heat-Resistant PLA Gets a New Name
Polymaker has had a busy 2026. In July, the company released HT-PLA Pro — a heat-resistant PLA that doesn't deform under its own weight at temperatures that would ruin standard PLA. And across the product line, the familiar PolyTerra name is being phased out in favor of Panchroma, a new brand family that Polymaker says better reflects what the materials actually do.
The rebrand hasn't changed the filament itself. Panchroma Matte is the same formula as PolyTerra PLA — same bioplastic base, same cardboard spool, same matte finish. The name change is about clarity: "Panchroma" signals the wide color range, while "Matte" tells you the finish directly. Old PolyTerra stock will continue to ship until it sells through, and Polymaker has confirmed the formula is identical.
HT-PLA Pro: The Bigger News
HT-PLA Pro addresses one of PLA's biggest weaknesses: heat deformation. Standard PLA starts to soften around 55-60°C, which means a PLA part left in a hot car or near a heat source can warp or sag. HT-PLA Pro uses a modified formulation that maintains structural integrity at higher temperatures while keeping PLA's ease of printing — no enclosure needed, no high-temperature hotend required.
| Property | Standard PLA | HT-PLA Pro |
|---|---|---|
| Heat Distortion Temp | ~55°C | Significantly higher |
| Print Temp | 190-210°C | 190-220°C |
| Bed Temp | 50-60°C | 50-65°C |
| Enclosure Needed | No | No |
| Toughness | Standard | Improved |
Polymaker positions HT-PLA Pro as a bridge between PLA and engineering materials like PETG or ASA. It prints like PLA — low warp, easy bed adhesion, no fumes — but handles heat better. That makes it useful for parts that live in warm environments: car interiors, near electronics, or in industrial settings where standard PLA would fail.
What Else Is New
Polymaker also released Gradient Winter, a new color in the Panchroma Matte line that shifts between cool blue and white tones. And the Panchroma Dual Matte (formerly PolyTerra Dual) continues to expand its color combinations, with dual-color filaments that shift hue depending on viewing angle.
For existing PolyTerra users, the transition is straightforward: if you see Panchroma Matte on the shelf, it's the same filament you've been using. The formula hasn't changed, only the name on the box.
