Patent number: 11667077Abstract: 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.Type: GrantFiled: June 17, 2020Date of Patent: June 6, 2023Assignee: Airbus Operations GmbHInventors: Claus Fastert, Johannes Born, Konstantin Schubert

Patent number: 11548213Abstract: 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.Type: GrantFiled: March 25, 2020Date of Patent: January 10, 2023Assignee: Airbus Operations GmbHInventors: Claus Fastert, Dirk Elbracht, Johannes Born, Konstantin Schubert
