The molecular bonding pattern of TPU resembles the structure of classic polyurethanes. However, in this case the three-dimensional structure of the cross-linked building blocks is linear. Polymer chains are able to slide off each other. TPUs are thus fusible and can be processed like other thermoplastics. Yet, at the same time, they still possess properties of “classical” polyurethanes. This combination makes them very interesting – for laser sintering as well.
Material Spec Sheet
Laser sintering is used to build your design with this material.
The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model. After a print job is finished, the result is a big block of heated powder with the printed models contained inside.
