Benefits with Aurora material

Strong & flexible prints

SLS 3D prints that are both strong and flexible. Our process and our material create some unique 3D prints that can be bent, go back to their original shape, and do not break into thousands of small pieces.

  • Complex geometries
  • UV-resistant
  • Incredibly strong
  • Can be ordered in black or white

Unique container for a powder free office

The absolute biggest disadvantage of a powder bed 3D-printer (SLS) is the powder handling. We at Wematter have solved this with a very simple solution where you refill powder with our patented powder packaging. Pick up the package, place in the opening and turn it around. It couldn’t be easier.

3D-prints that last

In order to truly demonstrate the strength of our prints, we have let one of our employees hang freely in a 3D-printed chain made by us in Aurora material in the video below.

Our materials

Aurora PA11

Aurora PA11 is a Polyamide 11 based material made from 100 % bio-based substances which are used primarily in industrial applications. The material is a sustainable thermoplastic polymer that produces strong UV-stable prints, well suited for technical end-products.

Aurora PA11 has superior mechanical performance compared to polymers such as Polyamide 12 widely used in rapid prototyping. It also meets the USP Class VI requirements for medical applications.


Why choose Aurora PA11

Main benefits

  • Superior mechanical properties
  • Low risk of sink marks
  • Low water uptake
  • Flexible
  • High strength
  • Salt water resistant

Application areas

  • Functional prototypes
  • Functional parts
  • Housings
  • Mounts
  • Gears
  • Small complex parts

Aurora PA12

Wematter Aurora PA12

Polyamid 12 (PA12) is a material well suited for manufacturing of functional prototypes, manufacturing of individual units as well as serial parts.

Aurora PA12 has excellent resistance to greases, oils, fuels, hydraulic fluids, water, alkalis, and salt solutions as well as many solvents. It also has very good stress cracking resistance even in the presence of chemicals as well as damping of noise and vibration.

Why choose Aurora PA12

Main benefits

  • Excellent mechanical properties
  • Nice surface finish
  • Excellent recyclability
  • Good chemical resistance
  • Excellent surface resolution and feature detail

Application areas

  • Functional testing and functional prototypes
  • Parts for the automobile industry
  • Medical supplies
  • Pipelines and fittings for water mains
  • Industrial components
