An additively manufactured assembly including an additively manufactured component with an edge oriented with respect to a recoater blade direction and an non-contact support that does not form a part of the additively manufactured component, the additively manufactured support located adjacent the edge. A method of additively manufacturing a component includes additively manufacturing an component with an edge oriented with respect to a recoater blade direction simultaneous with additively manufacturing an non-contact support that does not form a part of the component, the additively manufactured support located adjacent the edge.

A method and apparatus for the generative manufacture of a three-dimensional component in a processing chamber, in which the steps “providing a metallic starting material in the processing chamber” and “melting the starting material by means of energy input” are repeated multiple times, wherein a process gas is provided in the processing chamber are disclosed. The method is characterized by the steps: 1) the hydrogen content of the process gas or a sample of the process gas is determined; 2) the oxygen content of the process gas or a sample of the process gas is determined by means of an oxygen sensor and/or the dew point of the process gas or a sample of the process gas is determined; and 3) the values for the oxygen content and/or the dew point determined in step 2 are corrected by means of the value for the hydrogen content determined in step 1.

A powder discharge unit for equipping and/or upgrading a device for generatively manufacturing a three-dimensional object by a selective layer-by-layer solidification of building material in powder form includes a powder container for receiving building material in powder form and a filling chamber for filling in building material in powder form into the powder container. The powder discharge unit is configured to fluidise the building material in powder form in the powder container and the building material in powder form in the filling chamber independently of one another.

A 3D object is additively formed via arranging non-conductive material relative to a receiving surface. During additive formation of the 3D object, a conductive channel is formed as part of the 3D object. In some instances, non-destructive fracture sensing is performed via measurement of an electrical parameter of the conductive channel.

A system and process of printing a package of expanded material (e.g., expanded starch, foam or other expanded material). The expanded material can be heated and extruded, poured, sprayed, or otherwise applied in malleable form that sets up to become a porous protective covering for an item to be packaged. In an example, a layer of expanded material is laid down, and the item in a protective covering (e.g., a plastic bag, sleeve, coating, etc.) is positioned on the layer of expanded material. Additional layers or expanded material may be applied, thereby encasing the item. The top surface of the expanded material may be flattened, such as by operation of a roller, press, or cutter. The top surface may be sprayed with a shellac sealant, paint, or other coating, to allow printing of a label on the top surface.
