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

Why choose HTPLA?

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

Annealing process

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

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

Ideal for

• Functional prototypes requiring increased thermal resistance.
• Parts for everyday use exposed to heat, abrasion, or sunlight.
• Jigs, fixtures and tooling used in workshops or industrial environments.
• Educational and research laboratories exploring performance materials.

Printing and storage tips

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

Summary

When your project calls for more than standard PLA, choose our Canadian HTPLA. It combines the ease of printing of PLA with the strength and heat resistance of an engineering-grade material, making this filament an ideal choice for functional, heat-resistant parts and long-lasting applications.
