Embodiment Construction

[0116] Refer below figure 2 , figure 2 An additive production device 100 is schematically shown. Additive production system 100 is designed such that component 102 is produced layer by layer. Component 102 is in particular a component of an aircraft. Component 102 may be a plastic component or a fiber reinforced plastic component or a mixture thereof. Member 102 may also contain metal inserts.

[0117] The additive production device 100 includes a print head 104 which is movable relative to a print bed 106 in a manner known per se.

[0118] In the printhead 104, a plurality of components may be disposed. Printhead 104 may include an additive manufacturing device 108 . Additive production device 108 is designed to produce component 102 layer by layer on print bed 106 . Additive production device 108 may have a housing 110 .

[0119] The additive production device 108 includes a heating element 112 to heat the thermoplastic to its melting point or higher. The heating ...

Abstract

The invention relates to an additive manufacturing device, an additive manufacturing method, a profile rod and an application thereof. The 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 is put forward 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. Theprofile 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.

Description

technical field [0001] The invention relates to an additive production device, which is designed for the additive production of components. Furthermore, the invention relates to an additive production method and a profile bar used in the method. Background technique [0002] The most common 3D printing application uses plastic materials in so-called Fused Filament Fabrication (FFF), where thermoplastic filaments are melted and applied to a print bed. The filaments may contain additives or reinforcements. The filament cools and solidifies again on the print bed. [0003] Usually, the filament is provided as a coil which is mounted in the vicinity of the print head or at a non-movable point of the 3D printer. In this case, the filament is fed to the print head via a suitable guide system, for example by means of Bowden wires. This enables the use of relatively long filaments, but comes with certain restrictions on the filaments used. [0004] A limitation may therefore be...
