Ultrasint® PA11

Polyamide 11 powder for Laser Sintering


Ultrasint® PA11, a bio-based material (castor oil), is an interesting alternative to PA12. Parts produced with this material show a high elongation at break, elasticity and high impact resistance. Typical applications are in environments where high deformations (e.g. film hinges) and/or exposure to special surroundings (e.g. chemical, detergents, oil) may occur. Due to its high ductility, it does not splinter in most crash situations. Ultrasint PA11 can be used for skin contact applications. It is processable on most common LS printers. Parameters for printing will be provided.

Typical applications are:

  • Car interior parts
  • Bumper components
  • Film hinges
  • Functional prototypes and spare parts
  • Medium-loaded series parts

Delivery Form & Warehousing:

Ultrasint PA11 powder should be stored at 15 – 25°C in its originally sealed package in a clean and dry environment.

Product Safety:

Mandatory and recommended industrial hygiene procedures and the relevant industrial safety precautions must be followed whenever this product is being handled and processed. Product is sensitive to humid environment conditions. For additional information please consult the corresponding material safety data sheets.

For Your Information:

Ultrasint® PA11 comes in solid black color. Electrical properties (e.g. volume resistivity, surface resistivity), chemical properties (e.g. resistance against particular substances) and tolerance for solvents are available upon request. Generally, these properties correspond to publicly available data on polyamides.
