3D printing PA 12 filled / Alumide

This polyamide-based powder material contains a halogenated flame retardant and is white. The chemical flame retardant forms a carbonizing layer in the event of a fire, which insulates and protects the underlying material. Due to its good refreshability, it is very economical compared to other flame-retardant materials. The laser-sintered components made of PA 12 with flame protection are both tensile and ductile.

Advantages of 3D printing PA 12, flame-retardant

• Very good flame protection
• High chemical resistance
• High tensile and elongation strength
• Grease and oil resistance

Fields of application for laser sintering PA 12, flame-retardant

The special flame retardancy of the polyamide makes 3D-printed PA 12 FR components particularly suitable for use in the aerospace industry. For aviation, the material fulfills the CS-25 certification requirements (Certification Specifications for Large Aeroplanes), or outdated JAR-25 (Joint Aviation Requirements). This means that the use of components made of PA 12 with flame protection is officially approved for large, turbine-powered aircraft with a total weight of 5,670 kg or more. PA 12 FR is also an economical material for laser sintering in electrical engineering.

Components made from the white PA 12 powder filled with glass beads impress with their high rigidity combined with good elongation at break, are particularly wear-resistant and thermally resilient. Thanks to the reinforcement with glass beads, this polyamide comes very close to the properties of glass fiber-reinforced plastic. If required, the powder can be infiltrated with color.

Advantages of 3D printing PA 12 GF

• High dimensional stability
• good elongation at break
• High thermal load capacity
• easy to process
• High detail resolution
• Very good long-term usability

Fields of application for 3D printing PA 12 GF

Laser sintering with PA 12 GF produces components that are particularly suitable for the automotive industry, especially for the engine sector, due to their high thermal resilience. PA 12 with glass is also a good choice as a molding material for deep-drawing tools. Within a short time, prototypes and fully functional series components can be produced using the SLS process.

The metallic grey Alumide, aluminium-filled PA 12 powder, is characterized by high rigidity, a metallic appearance and good post-processing options. The surfaces of Alumide components can be easily finished by grinding, polishing or coating. Machining is simplified by the chip-breaking effect of the aluminum filling. Alumide also impresses with its very high temperature resistance, which is reflected in its excellent dimensional stability at high temperatures. Parts made of Alumide can therefore be used functionally at high temperatures.

Alumide is an ideal material for 3D-printed components that have a metallic appearance but are made of lightweight plastic and yet are heat-resistant and durable. The SLS process with Alumide also produces very clean and detailed results.

Advantages of 3D printing Alumide

• Excellent dimensional accuracy
• Balanced ratio of density and stiffness
• Good thermal conductivity
• easy to machine
• High dimensional stability
• Metallic look

Fields of application 3D printing SLS Alumide

Thanks to its good mechanical and thermal properties, 3D printing of alumide objects is suitable for the automotive industry, for example for wind tunnel tests. Alumide is also frequently used in model making, partly due to the metallic appearance of the lightweight components. Metallic-looking prototypes and small series can be printed quickly with Alumide and are fully operational and functional.
