Polypropylene (PP): a production-grade SLS thermoplastic
It offers an excellent plasticity, high elongation, low moisture absorption and high durability. It is resistant to most acids and bases and has a slightly translucent appearance.
| 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. |
