Discover our blue HTPLA filament, made in Canada and designed for demanding applications that require exceptional heat resistance and durability. With a high-crystallinity PLA resin, this filament combines the ease of printing of standard PLA with superior thermal performance, ideal for finished parts, functional prototypes, jigs, and fixtures that retain their shape under heat and load.

Why choose Canadian HTPLA

• High heat resistance — withstands up to 85 °C, and even more after annealing.
• Increased strength and rigidity — improved mechanical stability compared to standard PLA.
• Easy printing — behaves like PLA on most FDM/FFF printers without an enclosure or specialized equipment.
• Locally manufactured in Canada — reliable quality, consistent performance, and quick availability from a trusted domestic source.

Annealing and use

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

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

Ideal applications

• Functional prototypes requiring higher thermal resistance.
• Final components exposed to heat, wear, or sunlight.
• Jigs, tooling, and fixtures used in workshops or industrial environments.
• Laboratories and educational projects exploring performance materials.

Printing tips and practical advice

• Printing settings: nozzle 210–230 °C, bed 60–70 °C, cooling 50–100% after the first layer.
• Enclosure: optional but useful for homogeneous layer bonding.
• Best performance: print with moderate retraction and slow cooling for optimal layer adhesion.
• Stability after printing: in case of warping during annealing, support the part with sand or salt to preserve its shape.
• Storage: store the spool in a dry place; PLA-based materials absorb moisture over time.

When your project demands more than standard PLA, opt for our blue Canadian HTPLA. It combines the printing simplicity of PLA with the robustness and thermal resistance of performance materials, making this filament the ideal choice for functional parts and durable applications.
