Our white 1.75 mm, 1 kg HTPLA filament, made in Canada, combines the ease of printing of PLA with the heat resistance of engineering materials. Designed with high-crystallinity PLA, it reaches a glass transition temperature of approximately 85°C (and can go higher after annealing), ideal for end-use parts, functional prototypes, jigs, and tools that need to maintain their shape and strength under heat or stress.
Why choose HTPLA?
-
High heat resistance: withstands temperatures up to 85°C and increases after annealing.
-
Increased strength and rigidity: improved mechanical stability compared to standard PLA.
-
Easy printing: prints like PLA on most FDM/FFF printers without an enclosure or specialized equipment.
-
Made in Canada: reliable quality, consistent performance, and quick availability.
Annealing Process
HTPLA printed parts can be heat-treated to unlock their full potential. Annealing increases crystallinity, improving strength and dimensional stability. Follow these steps:
- Preheat oven or water bath to 80–100°C
- Place the printed part on a flat surface (or in water for uniform heating)
- Anneal for 20–30 minutes
- Cool gradually to room temperature before handling
Ideal Applications
- Functional prototypes requiring increased heat resistance
- End-use parts exposed to heat, wear, or sunlight
- Jigs, tooling, and fixtures used in workshops or industrial environments
- Educational laboratories and research exploring performance materials
Recommended Printing Parameters
-
Nozzle Temperature: 210–230°C
-
Bed Temperature: 60–70°C
-
Fan Speed: 50–100% after the first layer
-
Enclosure: optional, but helps achieve uniform layer bonding
Usage and Storage Tips
-
Optimize layer adhesion: print with moderate retraction and slow cooling for better layer-to-layer adhesion
-
Prevent warping during annealing: support parts with sand or salt if necessary
-
Storage: store the spool in a dry place; PLA-based materials can absorb moisture over time
When your project demands more than standard PLA, choose our Canadian-made HTPLA. It offers the printing simplicity of PLA while providing the robustness and heat resistance expected of an industrial-grade material—the ideal solution for functional, heat-resistant parts and durable end-use applications.
