A deposition apparatus and a deposition method are described. The deposition apparatus includes an accommodating element, a plurality of lasers and a carrier. The accommodating element is configured to accommodate a material. The lasers are disposed at a periphery of the accommodating element, and are configured to simultaneously emit a plurality of laser beams toward the material to melt the material to form a deposition liquid. The carrier is disposed under the accommodating element and the lasers, and are configured to carry the deposition liquid.

A method for printing an object using a high power one-dimensional (1D) line laser imager for selective laser sintering of thermal plastics. The technique is a two-step process. First, a layer of fresh powder is deposited on top of an existing powder bed. Second, the powder is sintered with the line laser print head. The laser is modulated at the source or with a spatial light modulator. Multiple passes or imagers can be used for increased part width and productivity. Using the relative travel between energy receiving surface and the laser print head in the direction perpendicular to the laser imaging line, a 2D pattern is imaged. Multiple print head can be aligned and joined to form a wider laser print head.

A method for producing a 3D structure based on the object of specifying a solution by which the layers are built up more reliable and more precisely in a 3D printing method. Specifically, by analyzing the data of the 3D structure to be produced, by identifying critical areas within the 3D structure to be generated, and by reducing the travel speed of working equipment of the 3D printer over the construction field at least temporarily if a critical area is identified while producing the 3D Structure.

The present disclosure provides three-dimensional (3D) printing systems, apparatuses, software, and devices for the production of at least one requested 3D object in a printing cycle, e.g., a control system. The 3D printing includes, or is operatively coupled to, a metrological detection system configured to facilitate assessment of at least one characteristic of the 3D printing, e.g., relating to height. The 3D printing includes synchronization of various operations, and resulting objects printed in the 3D printing system.

A method of manufacturing a modeled body includes: modeling including applying a modeling solution to each layer of powder laid in a layer, to solidify the powder to model a solidified object; sintering the solidified object to obtain a sintered body of the solidified object; and removing a sacrificial body from the sintered body, to obtain a modeled body. At the modeling, the modeling solution is applied to a modeled body area in the solidified object and a border area in the solidified object such that, after the modeling solution is applied, a density of the powder at the border area is smaller than a density of the powder in the modeled body area. The modeled body area corresponds to the modeled body. The border area corresponds to a border between the modeled body and the sacrificial body.

A powder bed additive layer manufacturing apparatus for manufacturing a component, the apparatus including a base plate including a set of axes X, Y, Z and a first re-coater blade. The base plate includes a build surface for receiving powder, and the build surface includes a non-planar surface profile for complementing the shape of a component non-planar surface. The first re-coater blade has a blade profile that corresponds with a non-planar surface profile of the build surface. The first re-coater blade is configurable such that it can traverse across the build surface, for providing a layer of powder having a consistent depth across the non-planar build surface during the manufacturing process.

A method of depositing powder in an additive manufacturing system includes driving a recoater along a drive axis and oscillating the recoater along an oscillation axis. The recoater is oscillated while the recoater is driven along the drive axis to overcome the effect of one or more particle movement restriction mechanisms for smoothing powder deposited in a build chamber of an additive manufacturing system.

A fabrication apparatus includes a forming device, an application device, an acquisition device, and circuitry. The forming device forms a layer containing powder. The application device applies a fabrication liquid to the layer formed by the forming device. The acquisition device acquires surface information of a surface of the layer. The circuitry controls at least one of the forming device or the application device to change at least one of an operation of the forming device or an operation of the application device based on the surface information acquired by the acquisition device.

An additive manufacturing system can include a powder dispenser; a gate adjacent to the powder dispenser; a recoater blade system; and a control operable to move the gate with respect to the powder dispenser to selectively dispense powder from the powder dispenser.
