Our Canadian-made HTPLA delivers next-level performance for demanding applications that require exceptional heat resistance and durability. Engineered from a high-crystallinity PLA resin, this advanced formulation offers the easy printability of standard PLA while reaching a glass transition temperature of 85 °C—and even higher when annealed. Perfect for end-use parts, functional prototypes, jigs, and fixtures that need to maintain strength and shape under heat or load.

✅ Why choose HTPLA?

• High-temperature resistance — Withstands heat up to 85 °C, and even higher after annealing.
• Enhanced strength and rigidity — Improved mechanical stability compared to standard PLA.
• Easy to print — Prints like standard PLA on most FDM/FFF printers without enclosure or specialized hardware.
• Locally made in Canada — Reliable quality, consistent performance, and fast availability from a trusted domestic source.

🔥 Annealing process

Printed HTPLA parts can be heat treated to unlock their full potential. Annealing increases crystallinity, improving both heat resistance and dimensional stability. Simply follow these steps:

1. Preheat your oven or hot water bath to 80 – 100 °C.
2. Place the printed part on a flat surface (or in water for even heating).
3. Allow it to anneal for 20 – 30 minutes.
4. Cool gradually to room temperature before handling.

This process allows HTPLA to achieve its maximum high-temperature strength and stability—ideal for engineering-grade applications.

🎯 Ideal for:

• Functional prototypes requiring higher thermal resistance.
• End-use components exposed to heat, friction, or sunlight.
• Jigs, fixtures, and tooling used in workshop or industrial environments.
• Educational and research labs exploring performance-grade materials.

🛠️ Recommended print settings

• Nozzle temperature: 210 – 230 °C
• Bed temperature: 60 – 70 °C
• Cooling fan: 50 – 100% after the first layer
• Enclosure: Optional, but helps maintain consistent layer bonding

📋 Filament specifications

• Diameter: 1.75 mm (± 0.05 mm)
• Weight: 1 kg spool
• Material: High-Crystallinity PLA (HTPLA)
• Heat Resistance (Tg): ~ 85 °C unannealed, higher when annealed
• Made in Canada
• Vacuum-sealed with desiccant for moisture protection

💡 Tips for best performance

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

🧾 Summary

When your project needs more than standard PLA, reach for our Canadian-made HTPLA. It combines the simplicity of PLA printing with the toughness and heat performance of engineering-grade materials—making it the perfect upgrade for functional, heat-resistant parts and durable end-use applications.
