SPL501 High Strength PLA 3D Printing Filament High Heat Resistance Rigidity

Product Description

SPL501 is a high optical purity PLA resin (L-lactide >99%, melting point >170°C) designed for producing high-performance 3D printing filaments.

• Raw material appearance: Pellets are off-white/creamy (normal for PLA). Final filament can be semi-transparent or custom-colored.

• Key properties: High mechanical strength, rigidity, and heat deflection resistance (HDT ~60-70°C after annealing).

• Applications: Functional prototypes, jigs & fixtures, automotive parts, electronic housings, and tools requiring better heat resistance than standard PLA.

• Processing: Compatible with standard single-screw extrusion for filament making. Dry pellets at 80°C for 4-6h before extrusion (moisture <50ppm).

• Printing recommendations: Nozzle temp 210-230°C, bed temp 50-70°C, cooling fan as needed. Annealing improves heat resistance.
