HTPLA Yellow Filament – 1.75 mm, 1 kg

Our Canada-made HTPLA delivers industrial-grade performance for the most demanding applications, combining high heat resistance with simplified printability. Designed from a high-crystallinity PLA resin, this filament offers the ease of printing of standard PLA while reaching a glass transition temperature of around 85 °C — and much higher after annealing. Ideal for end-use parts, functional prototypes, jigs, and tooling that must retain strength and shape under heat or load.

• High heat resistance: withstands temperatures up to 85 °C and can gain more after annealing.
• Increased rigidity and strength: improved mechanical stability compared with standard PLA.
• Easy printability: prints like PLA on most FDM/FFF printers without an enclosure or specialized equipment.
• Locally made in Canada: reliable quality, consistent performance, and fast availability.

Annealing process to unlock the full potential of HTPLA. Annealing increases crystallinity, improving heat resistance and dimensional stability. Follow these steps:

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

Ideal for:

• Functional prototypes requiring increased heat resistance.
• Final parts exposed to heat, friction, or sunlight.
• Jigs, tooling, and fixtures used in workshops or industrial settings.
• Educational and research labs exploring high-performance materials.

Tips for better performance:

• Print with moderate retraction and slow cooling for better layer adhesion.
• If warping appears during annealing, support the part with sand or salt to preserve its shape.
• Store the spool in a dry environment — PLA-based materials can absorb moisture over time.

In summary, when your projects require more than standard PLA, turn to our Canadian HTPLA. Combining the ease of printing of PLA with the strength and heat resistance of an engineering-grade material, it is the ideal solution for functional, heat-resistant parts and durable applications.
