TPU 95A

Material Info

About

TPU 95A is a flexible thermoplastic polyurethane (TPU) material used in FDM 3D printing for applications that require durability, elasticity, and impact resistance. It is well suited for functional prototypes and end use parts that undergo repeated bending, stretching, or mechanical stress, including protective covers, flexible housings, seals, gaskets, and wear resistant components.

With a Shore hardness of 95A, TPU 95A provides an excellent balance of flexibility and strength. Its high elongation at break allows parts to flex without cracking, while maintaining the toughness needed for demanding applications. Compared to rigid thermoplastics, TPU 95A offers greater resilience and shock absorption, making it ideal for components that require both mechanical performance and long term durability.

TPU 95A is commonly used across industrial, consumer, automotive, and engineering applications where flexible, rubber-like properties are essential. The material is also designed for reliable printability on a wide range of FDM 3D printing systems, helping accelerate product development from prototype to production.

Design Guidelines

Bounding Box

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

A supported wall is connected at least on two sides of the wall, while an unsupported wall is connected only on one side of the wall. Walls that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wall geometry of the model. Please consider the size of your model and reinforce the walls or add support structures as needed as minimum guidelines will not always be adequate for large models.

Wires

A wire is a circular, rectangular or even triangular feature that is thinner in its unconnected directions than its length. A supported wire is connected at least on two sides of the model, while an unsupported wire is connected on one side of the model. Wires that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wire geometry of the model. Please consider the size of your model and reinforce the wires or add support structures as needed as minimum guidelines will not always be adequate for large models.

Details

For text, the ratio between width and depth, should be 1:1 and sans-serif fonts are preferred for line weight consistency.

Clearance

Clearance is the space between two individual parts in a model. If the space among the individual parts do not meet the minimum clearance, then parts can fuse together or can be difficult to clean. This is important for movable pieces like hinges, gears, etc.

Sprues

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

Dimensional tolerance is ±0.5 mm plus ±0.2% of the longest axis. For example, a part measuring 50 x 50 x 100 mm may vary by ±(0.5 mm + 0.2 mm) = ±0.7 mm in any direction.
