The Ultimate Guide to 3301PA Nylon: The Industrial Powerhouse of SLS 3D Printing

Processing tips (injection molding & extrusion)

• Drying: Critical. Typical drying: 80–90°C for 3–6 hours (follow specific grade datasheet).
• Melt temperature: Mid-to-high range for nylons; follow supplier recommendations (commonly 230–300°C depending on grade/fillers).
• Mold temperature: Elevated mold temps (60–90°C) improve surface finish and reduce sink/voids for thicker sections.
• Screw design: Standard engineering-plastic screw with compression ratio suitable for nylon; avoid excessive shear to prevent degradation.
• Moisture control: Process with low moisture content for dimensional control—some applications intentionally condition parts to service moisture level for final properties.
• Post-molding: Annealing may reduce residual stress and warpage for critical parts.

Typical SLS settings:

• Density: ~1.15 g/cm³
• Tensile Strength: ~80 – 90 MPa
• Yield Strength: High rigidity and toughness.
• Elongation at Break: ~10–30% (Lower than extruded PA6, but offers higher dimensional stability).
• Impact Strength: High impact resistance, particularly in dry conditions.
• Heat Deflection Temperature (HDT): ~160°C – 180°C.
• Water Absorption: Approx. 8–10% at saturation in water. (Note: Cast nylon has slightly lower moisture absorption than extruded PA6).
