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.
|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)|
|Minimum wall thickness||1 mm, but living hinges are possible at 0.3 mm|
|Layer thickness||0.12 mm|
|Maximum part dimensions||The maximum build envelope is 630 x 330 x 560 mm|
|Surface structure||Unfinished parts typically have a grainy surface but all kinds of fine finishes are possible. Laser-sintered parts can be sandblasted, colored/impregnated, painted, covered and coated.|
How Does Laser Sintering Work?
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.
