PA 2241 FR is a flame-resistant polyamide (PA 12) material, with excellent long-term stability and chemical resistance. Owing to its flame-retardant quality, this high-performance plastic is suitable for aeronautics and aerospace applications in accordance with FAR 25.853.
This material is also available in Airbus certified grade, according to AIPI 03-07-022.
|Standard lead time||Minimum of 4 working days , depending on part size, number of components and finishing degrees|
|Standard accuracy||± 0.3% (with lower limit on ± 0.3 mm)|
|Layer thickness||0.10 mm|
|Minimum wall thickness||1 mm, but living hinges are possible at 0.3 mm|
|Maximum part dimensions||630 x 330 x 550 mm|

Laser Sintering is a laser-based technology that uses solid powder materials, typically plastics. A computer-controlled laser beam selectively binds together particles in the powder bed, by raising the powder temperature above the glass transition point after which adjacent particles flow together. As the powder is self-supporting, no support structures are necessary.
