Our white HTPLA filament, 1.75 mm, 1 kg, made in Canada, combines the ease of printing of PLA with heat resistance worthy of engineering materials. Designed in high-crystallinity PLA, it reaches a glass transition temperature of around 85 °C (and can go even higher after annealing), ideal for end-use parts, functional prototypes, jigs, and tools that must maintain their shape and strength under heat or stress.

Why choose HTPLA?

• High heat resistance: withstands up to 85 °C and increases after annealing.
• Increased strength and rigidity: improved mechanical stability compared with standard PLA.
• Easy printing: prints like PLA on most FDM/FFF printers without an enclosure or specialized equipment.
• Made in Canada: reliable quality, consistent performance, and fast availability.

Annealing process

HTPLA printed parts can be heat treated to reveal their full potential. Annealing increases crystallinity, improving strength and dimensional stability. Follow these steps:

• Preheat the oven or water bath to 80–100 °C
• Place the printed part on a flat surface (or in water for even heating)
• Anneal for 20–30 minutes
• Let cool gradually to room temperature before handling

Ideal applications

• Functional prototypes requiring increased heat resistance
• End-use parts exposed to heat, wear, or sunlight
• Jigs, tooling, and fixtures used in workshops or industrial settings
• Educational labs and research exploring performance materials

Recommended print settings

• Nozzle temperature: 210–230 °C
• Bed temperature: 60–70 °C
• Cooling: 50–100 % after the first layer
• Enclosure: optional, but helps achieve uniform layer bonding

Usage and storage tips

• Optimize layer adhesion: print with moderate retraction and slow cooling for better layer-to-layer adhesion
• Prevent warping during annealing: support parts with sand or salt if needed
• Storage: keep the spool in a dry place; PLA-based materials can absorb moisture over time

When your project calls for more than standard PLA, choose our Canada-made HTPLA. It offers the ease of printing of PLA while providing the toughness and heat resistance expected from an industrial-grade material — the ideal solution for functional, heat-resistant parts and durable end-use applications.
