PA

Polyamide (nylon) has been one of the most trusted engineering materials in industry for decades - from gears and bearings to electrical insulators. BEDROCK 3D® PA brings that proven reliability into the world of 3D printing, with a smart advantage: its copolyamide 6/66 formulation delivers a lower melting point than pure PA6 or PA66, meaning it can be processed on standard FFF printers without the need for industrial high-temperature hardware.

At the same time, none of the tough, wear-resistant characteristics that polyamide is known for are sacrificed. Thin-walled parts take on a semi-flexible nature, while thicker geometries are exceptionally rigid and strong - ideal for functional prototypes and end-use parts that need to perform under real-world conditions.

Material Highlights

• Toughness & Impact Resistance
  A high elongation at break makes BEDROCK 3D® PA resistant to sudden shocks and dynamic loads, even at low temperatures. It offers superior impact resistance compared to standard PA6 and PA66.
• Excellent Wear Resistance
  Naturally smooth and wear-resistant, this material is ideal for moving parts, sliding components, and surfaces subject to regular contact and friction.
• Fatigue Resistance
  BEDROCK 3D® PA maintains its properties under repeated loading cycles, making it well-suited for dynamically stressed and cyclically loaded applications.
• Chemical Resistance
  Resistant to oils, greases, and a wide range of chemicals — an essential property in industrial and mechanical environments.
• Low Melting Point - Broad Printability
  With a nozzle temperature of 220–250 °C, this filament is compatible with most common FFF printers, requiring no hardware modifications.
• Electrical Insulation
  PA has inherently strong electrical insulating properties, making it suitable for high-grade electrical components and enclosures.

Recommended
Use a closed printer for best results. If no active heating is available, keep the printer enclosed and preheat the bed for ~30 minutes before printing to stabilize the chamber temperature.

Drying recommendations
Essential for PA. Dry at 70 °C for 4–16 hours in a hot air dryer to ensure printability. For optimal mechanical properties, dry at 80 °C in a vacuum oven for at least 40 hours. Keep filament dry at all times to maintain consistent material properties.
