  • Publication number: 20200398486
    Abstract: For increasing the speed in 3D printing, for avoiding the conveying elements slipping from the conveyed semi-finished product, and for improving the transmission of force from the conveying elements to the semi-finished products to be conveyed, a conveying installation is provided for an additive manufacturing machine. The conveying installation for conveying a semi-finished product comprises a longitudinal conveying mechanism which by means of a periodic movement of at least one conveying element conveys the semi-finished product along a conveying direction which is parallel to the semi-finished product longitudinal axis. The conveying element when moving in the conveying direction acquires the semi-finished product, and when moving counter to the conveying direction is released from the semi-finished product. This results in a movement of the semi-finished product in the conveying direction.

  • Publication number: 20200307069
    Abstract: A method of using solid profile rods instead of the usual filament coils for additive manufacturing methods such as 3D printing for industrial applications such as aircraft manufacturing, and to enable a more rapid production of fiber-composite components. The additive manufacturing device, or the 3D printer which generates the component layer by layer, respectively, comprises a material magazine in which a plurality of profile rods are stored. The profile rods are pre-tailored and are adapted to the component layer by layer. The profile rods, when printing, are successively retrieved from the material magazine and, by way of an infeed installation, guided to the nozzle of the additive manufacturing installation and subsequently applied to the printing bed so as to form the component layer by layer.

  • Publication number: 20160375670
    Abstract: In a method for producing a component from a fiber-reinforced composite material, a semifinished product, containing reinforcing fibers, is disposed on a support surface. The semifinished product is covered with a film, draped, in at least one portion, such that at least one fold, extending from the support surface, is produced. A sealing tape is applied along an open edge of the fold, to seal off a space, defined by the support surface and the film, from the ambient atmosphere, in the region of the fold, such that two mutually opposite fold walls are formed partly by the film and partly by the sealing tape. A clip is applied over the fold such that the clip applies a clamping force, which presses the mutually opposite fold walls of the fold against each other. A vacuum is generated in the space defined by the support surface and the film.
