Discover our Canadian HTPLA filament with high crystallinity, specially designed for functional parts requiring heat resistance and durability. This advanced PLA offers the printability benefits 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 rapid availability for your critical projects.
Why choose HTPLA?
-
High thermal resistance — Tolerates temperatures up to 85 °C, and even more after annealing.
-
Improved rigidity and strength — Mechanically more stable than standard PLA.
-
Easy printing — Performs like PLA on most FDM/FFF printers without enclosure or specialized equipment.
-
Locally made — Produced in Canada for reliable quality and fast availability.
Annealing process
Parts printed in HTPLA 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 even heating).
- Received 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, fasteners and tools used in workshops or industrial environments.
- Educational and research laboratories exploring performance materials.
Filament specifications
-

-
Weight: 1 kg
-
Material: High Crystallinity PLA (HTPLA)
-
Thermal resistance (Tg): ~85 °C unannealed, higher after annealing
-
Manufacturing: Made in Canada
-
Protection: Vacuum-sealed with desiccant for moisture protection
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 shrinkage and slow cooling for better adhesion between layers.
-
Post-treatment: If the parts become deformed during annealing, hold them 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 requires 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 durable applications.
