HP Multi Jet Fusion:
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.

Material Properties
Surface properties
Since the raw material is in powder form, the surface produced after 3D printing is slightly rough. The roughness values are between Ra 6 – 12 µm, depending on the geometry and orientation.
Color
In the additive manufacturing process, the white TPU powder is given a black color. The components are thus completely black on the inside. However, a white component remains on the surface, resulting in the gray production color typical of Multi Jet Fusion. For technical reasons, this is rather inhomogeneous with light and dark areas.

Accuracy
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.

Finishing
Coloring
Coloring in black is possible.
Painting
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.
Design Guidelines
Minimum Wall Thickness
The minimum wall thickness should not be less than 1 mm. For longer objects/surfaces or for objects subject to mechanical loads, you should increase the wall thickness.
Cavities
Hollowed out objects can be printed, but openings (min. 10 mm diameter) must be inserted so that excess material can be removed. For larger cavities, you should plan for several openings. The source material is compacted during the printing process, so excess material is very difficult to remove.
Spacing
Keep a spacing of min. 0.5 mm for grooves or walls that are close to each other. Individual objects (“shells”) must always be uploaded as a separate file, unless they are firmly connected to each other.
Resolution
Details up to a size of approx. 0.5 mm can be displayed.
Interlocked Objects
Interlocked objects can be printed. Please note the minimum distance between the objects of min. 0.5 mm. Also make sure that the corresponding areas are accessible to remove excess material powder.
Size
The object should not be larger than 370 x 274 x 380 mm.

Applications
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 series production and is widely used in industry and medicine.
Shock absorption/damping
Due to its elasticity, the material can be used for damping or shock absorption similar to a hard rubber. For this application, it is also possible to produce grid structures without any problems. Depending on the wall thickness and geometry of the grids, different “hardnesses” can be achieved and optimized accordingly for the respective application.
Elastic grips/grippers
Geometrically complex, workpiece-friendly grippers can be printed for use in robotics or similar applications.
Covers
For high shock or dynamic loads, TPU can also be used for housings or protective covers.
Orthotics
TPU is ideal for many orthotic applications due to its flexibility and resilience.
