TPU 74D: Controlled Flexibility
TPU 74D combines mechanical strength with moderate flexibility. It is ideal for manufacturing technical parts requiring impact absorption, durability, and wear resistance.
| Standard lead time | About 4 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) to 0.012 in (0.3 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 13.78 x 15.75 x 15.75 in (350 x 400 x 400 mm). |
| Surface structure | Unfinished parts typically have a rough surface but all kinds of fine finishes are possible. FFF/FDM parts can be smoothed, painted and coated. |
