3D printing PA 6 / polyamide 6

Polyamid 613

PA 6 in 3D printing: even better with PA 613

The plastic polyamide 6 (PA 6) is a semi-crystalline thermoplastic that is mainly used in vehicle technology and automotive engineering. Polyamide 6 has a high temperature resistance. Thanks to their good mechanical properties, printed components made of PA 6 are fully functional, temperature stable and resistant to mechanical wear and chemicals such as power and lubricating greases.

New at FKM: PA 613 in 3D printing
To offer even better component quality, we have now replaced the classic PA 6 plastic powder with a further development that combines the best properties of PA 6 and PA 12: Components made of the new material PA 613 are more mechanically stable and offer increased resistance to chemicals and moisture compared to parts made of PA 6 and PA 12. Their melting temperature is also higher, which has a positive effect on their fire protection properties, especially for interior components in the automotive sector.

  • Advantages of 3D printing PA 613
  • High strength
  • High rigidity
  • High chemical resistance
  • Low moisture absorption
  • High temperature resistance
  • Excellent surface resolution and detail
  • Attractive surface finish

Fields of application of 3D printing PA 613
PA 613 is a good choice for the production of functional prototypes with high strength and rigidity. The material is also an outstanding choice for ready-to-install components in the automotive, aerospace and medical industries. It is additionally suitable for the production of tools such as moulds and inserts.

Prototype of a Air Duct Adapter

  • Made of the temperature-resistant plastic PA 6, which is finished on surfaces. For this purpose, the component was first smoothed with FKM smooth®, then dyemansion dyed black and then compacted blasted.

  • Depowdering, FKM smooth®, dyemansion dyed, compaction blasting |  
  • Dimensional and visual inspection |  

Plastic motor mount

  • Engine mounts are exposed to a permanent load – the engine weight – and must also support the entire engine torque. Until now, they have always been made of aluminum. This new engine mount is manufactured in series from the high-strength and temperature-resistant plastic PA 6. In terms of design, the main load direction has been optimized in such a way that the plastic part meets the high mechanical requirements.

  • Dimensional and visual inspection |  

Cover cap for vent flap

  • This coating cap is manufactured in series from the high-strength and temperature-resistant plastic PA 6. The serial parts are finished ready for installation. First smoothed (trowalized), then dyemansion dyed and finally compacted blasted.

  • PA 6 MF black |  
  • Depowdering, Trowalizing, Dyemansion Dyed, Compaction Blasting |  
  • Dimensional and visual inspection |  

Guide part for motor area

  • The guide part acts as a water collector and keeps accumulated water safely away from sensitive engine components. It was made from the temperature-resistant plastic PA 6 and first smoothed with FKM smooth®, then colored black with Dyemansion and finally compaction blasted.
  • Series |  
  • Polyamide 6 |  
  • Depowdering, FKM smooth®, dyemansion dyed, compaction blasting |  
  • Initial sample inspection report with release |  
  • Automobil: Passenger car |

Polyamide 613: a plastic for high demands

PA 613 is a thermoplastic polyamide powder that we are now using in a completely new way in SLS technology. The material is a further development of PA 12 and is characterised by its higher strength, rigidity and chemical resistance. PA 613 is resistant to moisture and chemicals such as acids, alkalis and solvents and retains its shape and dimensions even at higher temperatures. Due to its excellent properties, PA 613 is a promising option for demanding applications in additive manufacturing.

Maximum installation space: 360 x 360 x 500 mm
