In an example, a method is described that includes building a first layer of a three-dimensional heterogeneous object in a first plurality of passes of an additive manufacturing system. An electronic component is inserted directly into the first layer. The electronic component is then fused to the first layer in a second plurality of passes of the additive manufacturing system.

The present invention relates to an apparatus for the additive production of components. The apparatus comprises an additive production head having an extrusion nozzle and a plasma source arranged around the extrusion nozzle or integrated into the extrusion nozzle for the generation of plasma. The present invention additionally relates to a method for the additive production of components. A plasma is generated in the method with the aid of a plasma source arranged around an extrusion nozzle of an additive production head or integrated into the extrusion nozzle. A material is furthermore melted, pressed through the extrusion nozzle, and deposited in layers. In addition, a treatment by the plasma takes place in which a surface on which the material is deposited in layers is treated with the plasma before the deposition and/or the material is treated with the plasma before, during, and/or after the deposition.

A method for printing a three-dimensional part with an additive manufacturing system, which includes providing a part material that compositionally has one or more semi-crystalline polymers and one or more secondary materials that are configured to retard crystallization of the one or more semi-crystalline polymers, where the one or more secondary materials are substantially miscible with the one or more semi-crystalline polymers. The method also includes melting the part material in the additive manufacturing system, forming at least a portion of a layer of the three-dimensional part from the melted part material in a build environment, and maintaining the build environment at an annealing temperature that is between a glass transition temperature of the part material and a cold crystallization temperature of the part material.

Some examples include a method of operating an additive manufacturing machine including spreading a build material in a first direction across a build surface to form a layer, the layer having a thickness, decreasing a distance between a spread mechanism and the build surface, and translating the spread mechanism in a second direction opposite the first direction over the build surface to reduce the thickness of the layer.

An example of a three-dimensional (3D) printing kit includes a build material composition, an epoxy agent to be applied to at least a portion of the build material composition during 3D printing, and a fusing agent to be applied to the at least the portion of the build material composition during 3D printing. The build material composition includes a polyamide having an amino functional group. The epoxy agent includes an epoxy having an epoxide functional group to react with the amino functional group of the polyamide in the at least the portion. The fusing agent includes an energy absorber.

A method for the additive manufacturing of a composite component in which a fluid matrix material by way of an additive manufacture is introduced successively into a manufacturing device with the formation of an additively manufactured component. A reinforcing element is at least partly introduced into the fluid matrix material and/or arranged on the fluid matrix material.

A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

A method for forming a three-dimensional object by extruding ink droplets from ink-jet heads includes forming an inner build region of the object. A colored region is formed outside of the inner build region so as to color the object. A support region is formed outside of the colored region so as to support the object while the object is being formed. An intermediate region is formed between the inner build region and the colored region. The intermediate region is formed in such a manner that affinity between the intermediate region and the inner build region and affinity between the intermediate region and the colored region are higher than affinity between the colored region and the support region.
