Discover our high-crystallinity Canadian HTPLA filament, specially designed for functional parts that require heat resistance and durability. This advanced PLA offers the printability advantages of standard PLA while achieving a glass transition temperature of approximately 85 °C, and even better after controlled annealing. Designed and manufactured in Canada, it guarantees reliable quality, consistent performance, and quick availability for your critical projects.

Why choose HTPLA?

• High heat resistance — Tolerates temperatures up to 85 °C, and even more after annealing.
• Improved rigidity and strength — Mechanically more stable than standard PLA.
• Easy printing — Behaves like PLA on most FDM/FFF printers without an enclosure or specialized equipment.
• Local manufacturing — Produced in Canada for reliable quality and quick availability.

Annealing Process

HTPLA printed parts can be annealed to unlock their full potential. Annealing increases crystallinity, enhancing heat resistance and dimensional stability. Follow these steps:

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

Ideal for

• Functional prototypes requiring increased thermal resistance.
• Wear parts exposed to heat, abrasion, or sunlight.
• Jigs, fixtures, and tooling used in workshops or industrial environments.
• Educational and research labs exploring performance materials.

Printing and Storage Tips

• Printing temperature 210 – 230 °C, bed 60 – 70 °C, fan 50 – 100% after the first layer, enclosure optional but useful for uniform layer bonding.
• Optimization tips: Moderate retraction and slow cooling for better inter-layer adhesion.
• Post-processing: If parts warp during annealing, hold them down with sand or salt to preserve the shape.
• Storage: Store filament in a dry place, as PLAs can absorb moisture over time.

Summary

When your project requires more than standard PLA, choose our Canadian HTPLA. It combines the printing simplicity of PLA with the robustness and thermal resistance of an engineering-grade material, making this filament an ideal choice for functional, heat-resistant parts and durable-use applications.
