The Science Behind Engineering Filaments
Our materials are developed using advanced material science to meet the demanding requirements of modern manufacturing. Each formulation is tailored for specific performance needs, ensuring reliable performance even in harsh environments.
Key Innovations:
–Carbon Fiber Reinforcement: PA12-CF and PA6-CF incorporate 20% carbon fiber, dramatically enhancing mechanical properties like strength, toughness, and heat resistance.
–Polymer Hybridization: PC-ABS blends 70% polycarbonate (PC) and 30%
–Acrylonitrile-Butadiene-Styrene (ABS), modified with additives to strike the perfect balance between toughness and processability.
PA12-CF: The Lightweight Engineering Marvel
A high-strength, heat-resistant, and low-warping material ideal for precision applications.
Key Features:
Heat Resistance: Heat deflection temperature (HDT) of 175°C.
Exceptional Strength: Tensile strength of 100 MPa, flexural strength of 163 MPa.
Lightweight: Density of 1.04 g/cm³—lighter than many alternatives.
Low Warping: Minimal shrinkage for crack-free, high-precision prints.
Applications: Automotive components, mechanical parts, sports equipment.
Printing Tips:
1. Dry at 80°C for 12 hours or 110°C for 4 hours before printing
2. Use a hardened steel nozzle to prevent wear
3. Apply adhesive to the print bed for better adhesion.
4. Post-print annealing enhances performance.
