TESTS IN PROGRESS – EXPECTED AVAILABILITY FALL 2021
Nylon PA 6 flame-retardant (polyamide): a strong and tough FST engineering-grade SLS thermoplastic
It shows very good mechanical properties, such as high modulus, high strength and excellent thermal distortion stability. This material meets flammability standards, and is suitable for aerospace and automotive applications.
It can fulfil the requirements of functional applications regarding high accuracy and mechanical strength as well as high heat distortion temperature – properties.
| Standard lead time | About 7 working days, depending on part size, quantity, number of components and finishing degrees. |
|---|---|
| Standard accuracy | ±0.012 in (± 0.3 mm) - may vary depending on geometry. |
| Layer thickness | 0.004 in - 0.1 mm |
| Minimum wall thickness | 0.039 in - 1 mm |
| Maximum build dimensions | Dimensions are unlimited as components may be composed of several sub-parts. The maximum build envelope is 15 x 15 x 16 in (381 x 381 x 406 mm). |
| Surface structure | Unfinished parts typically have a grainy surface but all kinds of fine finishes are possible. Laser-sintered parts can be smoothed, painted and coated. |
