New 3D Printed PP Replaces PA in Prototypes and Small Series Production

PP Powder Processed by Selective Laser Sintering

Advanc3dMaterials GmbH has developed a new PP powder which can be processed by Selective Laser Sintering.

Polypropylene (PP) is the most commodity plastic material used in the world. The reason is that PP offers excellent mechanical properties at an attractive price. It is used in a wide range of industry for series production.

Alternative to Polyamide


The main application of Selective Laser Sintering (SLS) is prototyping and small series production based on polyamide powder (PA). Therefore, prototypes are not comparable with final parts of series production. Additionally, polyamide is more expensive than PP so that SLS is not competitive as it could be especially in comparison to injection molding.

AdSint® PP Flex


To close this gap, Advanc3dMaterials GmbH has developed a new PP powder which can be processed by Selective Laser Sintering.
  • AdSint® PP flex is characterized by an excellent plasticity, high elongation of 29%, low moisture absorption and durability. 
  • It is comparable to standard polypropylene and a very good alternative to PA. 
  • With this new SLS material prototypes and small series can be produced directly from PP, so that the installed material matches that of the serial production.

Applications


Like a regular polypropylene, AdSint® PP Flex can be used in a wide field of application:
  • Automotive 
  • Electrical
  • Sport industries 
  • Health care and orthopedic products 

It allows post processing like thermoforming or sealing. Above all, the recycling rate of 80-100% represents an important cost advantage compared to PA.
