摘要

The method for producing a three-dimensional structural element (108), comprises spraying a material of the three-dimensional structural element onto a shaping device (102) for forming the three-dimensional structural element in a powdered manner. A shaping element (110) of the shaping device is moved, so that the production and/or the processing of the three-dimensional structural element is enabled in a continuous process and so that the three-dimensional structural element is produced and/or processed without deflection of a moving direction of the three-dimensional structural element. The method for producing a three-dimensional structural element (108), comprises spraying a material of the three-dimensional structural element onto a shaping device (102) for forming the three-dimensional structural element in a powdered manner. A shaping element (110) of the shaping device is moved, so that the production and/or the processing of the three-dimensional structural element is enabled in a continuous process and so that the three-dimensional structural element is produced and/or processed without deflection of a moving direction of the three-dimensional structural element, where two shaping elements are moved past in a production direction of the structural element. The material of the structural element is sprayed on a shaping roller, a roller strip and/or a negative mold (114) of the shaping device. The material sprayed on the shaping device is pressed using a press roller, roller strip and/or a positive mold of a pressing device (106), and is heated. A spraying device, by which the material is sprayed onto the shaping device, is moved relative to the shaping device. The component of the material of the structural element is a duroplastic, thermoplastic or elastomeric material, and is an adhesive material or resin, where the fibers and/or filler material are admixed to the material of the structural element for reinforcement and short fibers, glass fibers and natural fibers are selected as a part of the admixed fibers. The material of the structural element is partially sprayed onto the shaping device in a liquid manner. A covering layer is adhered, sprayed or pressed onto the structural element using a pressure roller. An intermediate layer is applied onto the structural element before the application of the covering layer. A non-woven material is selected as material of the intermediate layer. An independent claim is included for a device for producing a three-dimensional structural element.
