About TPU (Thermoplastic Polyurethane) – 3D Printing Material
TPU (MJF) is a high-performing thermoplastic polyurethane (TPU) powder, enabling the production of elastomeric functional parts with the advantages of additive manufacturing, obtaining similar performance as injection molding. The parts made from TPU (MJF) are flexible, tough, and provide high elongation and impact resistance for applications such as soft grip systems, footwear, seating and protective gear. It’s also well-suited for soft non-marring tooling, flexible tubing, wheels and ducts. Parts printed from TPU (MJF) are gray naturally, and black when dyed or smoothed.

Design Guidelines
Bounding Box
Bounding Box Max
284 × 380 × 380mm
Bounding Box Min
1 × 1 × 19 mm
At least 1 extant dimension over 19 mm
The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted.

Escape Holes
Single Escape Hole Diameter (Min)
12.0 mm
Multiple Escape Hole Diameter (Min)
10.0 mm
A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.
Clearance
Min
0.8 mm
Sprues
3 mm thick, attached in at least 2 places per part
Sprues are wires that keep two or more parts together. Parts should be connected with a minimum of two sprues each. Please consider the size of your sprues and increase them as needed as minimum guidelines will not always be adequate for large models. If the sprues are within the guidelines and are broken, but there is no damage to your model, we will still ship them as is.

Accuracy
Accuracy
± 0.5mm, then ± 0.2% of longest axis
For example: a product with dimensions of 50 x 50 x 100 mm can be 0.5 mm + 0.002 * 100 mm = 0.7 mm bigger or smaller in any direction.
