German RepRap, FFF 3D printers’ manufacturer, developed a polyurethane (PU) material for its Liquid Additive Manufacturing (LAM) technology.

By collaborating with ebalta Kunststoff GmbH, manufacturer of polyurethane and epoxy resins, German RepRap will bring to market a material that is flexible enough to be used in a variety of applications and industries.

Unveiled at the PSE Europe 2017 event in Munich, this material brings a revolution to the market through its isotropic mechanical properties coming from both chemical crosslinking and its capability to be used in its liquid state, saving by this way time and on the other hand, removing the need for melting.

These mechanical properties open doors to the development of a wide range of new applications. For instance, prototyping models in a functional material or a flame retardant material with the exact specific strength.

PU are most of the time used as foams for insulation, mattresses, paint and adhesive systems.

For German RepRap, “polyurethanes are suitable for special applications, such as those requiring high resistance to wear. This makes them suitable for applications in virtually all industries, especially automotive, aeronautical, and construction.”
