A device and method for printing 3D articles including electronic and functional elements including 3D printer and a plasma jet printer based on a dielectric barrier atmospheric pressure plasma jet system in which both printing and in-situ treatment and post-deposition treatment can be carried out to tailor the materials characteristics. Plasma jet printer comprising of electrodes in the nozzle/print head for applying electric field and generating atmospheric plasma that could be used for non-gravity based highly directional printing in any direction. Integration of dielectric barrier plasma printer and plasma treatment jets with the 3D printer increases the capability of embedding high performance electronics in a 3D printed structure aiding in additive manufacturing of functional devices. Ability to use a range of materials for print head assembly including micro machined silicon increases the resolution of the plasma jet printer to sub-micron level.

The present disclosure generally relates to methods for additive manufacturing (AM) that utilize powder removal ports in the process of building objects, as well as novel support structures including powder removal ports to be used within these AM processes. The objects include walls defining regions of unfused powder. The powder removal ports include at least one tube aligned with an opening in the walls to allow removal of the powder. The methods include removing unfused powder from the enclosed space via the at least one tube.

An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. A clamping mechanism is movable relative to the powder support plate and defines a void for receiving a resilient sealing element around the aperture. An actuating mechanism, such as bolts or a linear actuator, moves the clamping mechanism toward the powder support plate to deform the resilient sealing element until the resilient sealing element contacts and forms a seal with the component.

A metal-ceramic article and method for creating the same is disclosed in which the article has undergone machining to remove outer surface volume. The article is then treated to enhance the characteristics of at least the machined surface to be comparable to the original surface. In the disclosed application the machining does not extend to an inner layer of the article in which the article consists purely of a metal.

Building is performed with a relatively small amount of material. Provided is a method for manufacturing a three-dimensional object. This method includes the steps of stacking a plurality of layers for forming an object; building a wall surrounding the object being formed; and supplying a material between the wall and the object being formed as a support material for supporting the object being formed.

A three-dimensional shaped article production method for producing a three-dimensional shaped article by stacking layers to form a stacked body includes a constituent layer formation step of forming a constituent layer which corresponds to a constituent region of the three-dimensional shaped article, a support layer formation step of forming a support layer which is in contact with the constituent layer and supports the constituent layer, and a sintering step of sintering the constituent layer, wherein the support layer is configured such that as compared with the volume decrement accompanying the sintering step of a space surrounded by the constituent layer from at least two directions, the volume decrement accompanying the sintering step of the support layer which supports the constituent layer in the space is larger.

A powder layer smoothing devices adapted for use with powder-layer three-dimensional printers are described. The smoothing devices include an oscillating smoothing device that includes a leading edge adapted to cut, remove, and redistribute excess powder in a powder layer. A leveling sled follows the leading edge to trowel and compact the powder in the powder layer.
