摘要： A 3D extrusion print process for producing multicolored three-dimensional objects is provided. The process produces mechanically stable, multicolored 3D objects with good color definition. The process according to the invention is based on coating, upstream of the printing head, of the polymer strand used for producing the actual object, and on fixing of the coating upstream of entry of the polymer strand into the printing head. Downstream of the extrusion process in the printing head, the coating remains predominantly at the surface of the extruded strand.

摘要： The invention relates to light guide plates, which are suitable for backlighting LCD monitors as well as information and advertising signs and which are illuminated at the edges and re-emit the light fed at the edges via at least one of the two surfaces located perpendicular to the edges. For the light of a light source that is fed at the edges to be able to leave the light guide plate again via one of the surfaces by overcoming total reflection, the light rays in the light guide plate have to be deliberately deflected. At one of the two surfaces of the light guide plate, the light guide plates are provided with optical impurities (2), which are protected against damage by a film (5). Furthermore, a method for the simplified application of said impurities is provided.
