Flexibility with very good impact resistance and heat insulationSpectrum S-Flex 98A is a filament based on thermoplastic polyurethane. In the area of additive manufacturing, S-Flex 98A is a material, which is characterized by a relatively simple and problem-free 3D printing process. An additional advantage that allows perfect printing is the excellent adhesion of the first layer of the manufactured part to the hot bed, whether it is made of glass, steel, plastic or any other material.Low processing shrinkage and very high flexibility reduce the risk of the edges of the finished parts significantly. The distinctive feature in the filament name - 98A - refers to the hardness of the material on the shore scale and classifies S-Flex 98A into the category of hard elastomers. From the perspective of the 3D printing process, this feature reduces the risk of filament deformation in the area of the feed system from filament to print heads. This allows a slightly faster pressure compared to othe
