About TPU (Thermoplastic Polyurethane) – 3D Printing Material
Thermoplastic Polyurethane, or TPU, is an industry-standard flexible, rubber-like material that is great for elastic end-use products. Printed using Selective Laser Sintering (SLS), a robust process that solidifies material layer-by-layer, TPU parts are durable and can include interlocking features.

Design Guidelines
Bounding Box
Bounding Box Max
200 x 200 x 200 mm
Bounding Box Min
15 x 15 x 0.7 mm
X + Y + Z ≥ 15.0 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.
Walls
Supported Wall Thickness Min
0.7 mm
Unsupported Wall Thickness Min
0.7 mm
Wires
Supported Wires Min
1.0 mm
Unsupported Wires Min
2.0 mm
Details
Details Min Embossed
1.0 mm high & wide
Details Min Engraved
1.5 mm high & wide
Escape Holes
Single Escape Hole Diameter (Min)
4.0 mm
Multiple Escape Hole Diameter (Min)
3.0 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
1.0 mm
Sprues
1.5 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
± 0.3- 0.7 mm for every 100 mm
For example: a product with dimensions of 50 x 50 x 100 mm can be up to 0.7 mm bigger or smaller in any direction.
