Ultrasint® TPU01

Ultrasint® TPU01 by BASF is a high-quality thermoplastic polyurethane (“TPU”), specifically designed for the Multi Jet Fusion process. This material is characterized by high elasticity and elongation at break, excellent surface quality, high abrasion resistance, and precision in detail. It is perfectly suited for mass production of sports equipment, shoes, automotive interiors, housings or protectors, and industrial tools. Thanks to its powder-based manufacturing and high process stability, it offers limitless design possibilities, enabling the production of even the most complex structures, such as lattice frameworks.

Surface Properties

Since the raw material is in powder form, the surface produced after 3D printing is slightly rough. The roughness values range from Ra 6 – 12 µm, depending on the geometry and orientation.


In the additive manufacturing process, the white TPU powder is coated with black color. As a result, the interior of the components is completely black, but the surface retains a white component, which contributes to the typical gray production color of Multi Jet Fusion. Due to technical reasons, this coloration is rather inhomogeneous with bright and dark areas.

Employee measuring manufacturing tolerance in the Multi Jet Fusion process

The general tolerance is 1 mm up to 100 mm outside dimension, above 0.9 % in X/Y and 1.5 mm up to 100 mm outside dimension, above 1.8 %. In the case of large-area, flat geometries, warpage may occur in addition. Due to the elastic or flexible material properties, 3D-printed products made of this material are only dimensionally stable to a limited extent and are easily deformable depending on the geometry.

Dip dyeing in black



Coloring in black is possible, but can significantly worsen the dimensional accuracy.
The material tends to swell, which can increase the tolerance by up to 3%. You can find more information under “Accuracy”.


Wet painting of TPU is possible in principle. However, this should not be used if the component in question is subject to strong dynamic stress, as in such a case the paint could come off at the points of movement.

minimum wall thicknesses

Minimum Wall Thicknesses
The minimum wall thickness should not be less than 1 mm. For longer objects/surfaces or objects subjected to mechanical loads, you should increase the wall thickness.


Hollowed objects can be printed, but openings (minimum 10 mm diameter) must be incorporated to allow excess material to be removed. For larger cavities, you should plan for multiple openings. The starting material is compacted during the printing process, making excess material removal challenging.


Maintain a minimum clearance of 0.5 mm for grooves or closely spaced walls. Individual objects (“shells”) must be uploaded as separate files unless they are firmly connected.


Details as small as approximately 0.5 mm can be represented.

geared objects

Geared Objects
Interlocking geared objects can be printed. Please observe a minimum distance of 0.5 mm between the objects. Also, ensure that the corresponding areas are accessible for the removal of excess material powder.


The object should not exceed 370 x 274 x 380 mm.

TPU processed in additive manufacturing (Multi Jet Fusion) is used wherever high loads occur or flexibility is required. The material has been consistently designed for additive serial production and is widely used in industry and medicine.

Shock Absorption/Cushioning
Due to its elasticity, the material can be used for cushioning or shock absorption similar to hard rubber. It is also possible to produce lattice structures for this application. Depending on the wall thickness and geometry of the lattices, different “hardnesses” can be achieved and optimized for the respective application.

Elastic Handles/Grippers

Geometrically complex, workpiece-friendly grippers can be printed for use in robotics or similar applications.


TPU can be used for housings or protective covers in cases of high impact or dynamic loads.


TPU is ideal for many applications in orthopedics due to its flexibility and durability.
