HTPLA High Temperature PLA Filament – Heat-Resistant Performance for Professional 3D Printing
HTPLA (High Temperature PLA) is an advanced performance-grade 3D printing filament designed for users who need high strength, durability, and superior thermal resistance. Formulated from high-crystallinity PLA resin, it offers the same easy printability as standard PLA while providing mechanical and thermal properties close to engineering-grade materials like PETG or ABS.
Ideal for engineers, designers, and makers, HTPLA is a trusted choice for creating functional prototypes, tooling jigs, and end-use parts that must withstand elevated temperatures. With a glass transition temperature of 85°C and even higher resistance after annealing, this filament bridges the gap between standard PLA and professional high-performance thermoplastics.
Why Choose HTPLA Filament?
- High Heat Deflection: Withstands up to 85 °C before annealing and exceeds 100 °C after heat treatment.
- Easy to Print: Prints on most FDM 3D printers with the same reliability as PLA—no enclosure required.
- Enhanced Mechanical Strength: Superior rigidity and impact resistance for functional parts.
- Annealable Performance: Heat treat your prints for maximum strength and dimensional stability.
- Low Warping & Odor-Free: Environmentally friendly and derived from renewable resources.
What is HTPLA Used For?
HTPLA is perfect for applications requiring heat and load endurance, such as:
- Engineering Prototypes – Functional models that simulate end-use performance.
- Automotive Parts – Lightweight components capable of resisting heat and vibration.
- Tooling & Fixtures – Reliable jigs and manufacturing aids that retain shape under stress.
- Consumer Goods – Durable prints for home, industrial, or educational use.
- STEM & Research Projects – Ideal for classrooms and labs exploring advanced materials.
Annealing Process for HTPLA
To maximize the performance of HTPLA, post-process your prints by annealing:
- Preheat your oven or hot-water bath to 100 °C.
- Place the printed part on a flat, heat-resistant surface.
- Anneal for 15–30 minutes to increase crystallinity and thermal resistance.
- Allow the part to cool slowly to maintain dimensional accuracy.
This simple treatment can increase heat deflection temperature (HDT) and overall part stiffness, making HTPLA one of the most versatile 3D printing materials available in Canada.
