This Thermoplastic Polyurethane is obtained by modifying Thermoplastic Elastomer (TPE). TPU is an ideal material for applications where flexibility, elasticity and good adhesion between layers are required, which is very important in FDM 3D printing. Another advantage is its high abrasion resistance and smooth surface finish, which minimises friction between contacting elements. In addition, this material shows good chemical resistance in contact with fats, oils and solvents.
