Black - Canadian-made HTPLA Filament - 1.75mm, 1kg

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: 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). Allow it to anneal for 20 – 30 minutes. 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.
