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

Annealing and use

Printed parts in HTPLA 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 even heating).
• Anneal for 20–30 minutes, then cool gradually to room temperature before handling.

Ideal uses

• Functional prototypes requiring higher thermal resistance.
• Final components exposed to heat, wear, or sunlight.
• Jigs, tooling, and equipment 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 a smooth bonding of the layers.
• 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 the shape.
• Storage: keep the spool in a dry place, PLA-based materials absorb moisture over time.

When your project requires more than standard PLA, choose our Canadian blue HTPLA. It combines the easy printability of PLA with the strength and heat resistance of performance materials, making this filament the ideal choice for functional parts and durable applications.
