Manufacturing installation and method for the additive manufacturing of components with a material overhang
A manufacturing installation for the additive manufacturing of components, each provided with at least one material overhang, has at least one building platform on which the particular component can at least partially be additively manufactured. In order to reduce the material consumption and the time to produce additively manufactured components, the manufacturing installation has at least one preferably electrically controllable support device with at least one movable support arm for the at least temporary holding of at least one support element, arranged on the support arm, during the additive manufacture of the particular component above the building platform.

3D printed objects with selective overcure regions
A method of manufacturing a three-dimensional (3D) object may include fabricating a support structure and fabricating the 3D object on the support structure, wherein the support structure contacts the 3D object at a support region of the 3D object. The method further includes overcuring the 3D object at an overcure region of the 3D object, wherein the overcure region is distinct from the support region, and removing the support structure from the 3D object. After removal of the support structure, a support mark remains on the 3D printed object where the support structure had contacted the 3D object, wherein the overcure region of the 3D object projects past the support mark.

Impregnation system for composite filament fabrication in three dimensional printing
Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Method for producing an object by generative manufacturing, component, in particular for an aircraft or spacecraft, and computer-readable medium
Methods for producing an object by generative manufacturing, a component, and a computer-readable medium. In one method, a sheet-like part is formed with bulges. In another method, a supporting structure is formed with an arch formed by arch segments converging in the buildup direction and meet at an arch tip. In another method, a supporting structure is formed with a strut of a cloverleaf-like cross-sectional shape. In another method, a supporting structure is formed with a sheet-like part connected to the object and formed to project obliquely forward from the object in the buildup direction. In another method, a supporting structure is formed with a sheet-like part extending substantially along the buildup direction, the sheet-like part formed with apertures. In another method, a supporting structure is formed with a sheet-like part connected to the object and, in a region of transition of the same to the object to be generated, has a perforation and/or a predetermined breaking edge along a contour of the object.

Methods and apparatus to identify additively manufactured parts
Methods and apparatus to identify additively manufactured parts are disclosed. An example apparatus includes a body, formed of layers layered substantially parallel to a base layer, composed of a first material having a first density, a first indicium embedded internally in the body as a void, and a second indicium on an external surface of the body, the second indicium aligning with the first indicium.
ADDITIVE FABRICATION SUPPORT STRUCTURES
Techniques for evaluating support for an object to be fabricated via an additive fabrication device are provided. In some embodiments, a three-dimensional representation of the object is obtained and a plurality of voxels corresponding to the representation of the object is generated. A first supportedness value may be assigned to a first voxel of the plurality of voxels based on an amount of support provided by a support structure to the first voxel, and a second supportedness value determined for a second voxel of the plurality of voxels, wherein the second voxel neighbors the first voxel, and wherein the second supportedness value is determined based on the first supportedness value of the first voxel and a weight value representing a transmission rate of supportedness through voxels of the plurality of voxels.
