摘要： According to examples, a system may include a first carriage carrying a laying device that may form a build material layer over a build area and a first energy source that may apply energy onto the build material layer as the first carriage is moved over the build material layer. The system may also include a second carriage carrying an agent delivery device and a second energy source, in which the agent delivery device may selectively deliver an agent onto the layer of build material and the second energy source may apply energy onto the agent and the layer of build material as the second carriage is moved across the build material layer. The system may further include a controller to control movement of the first carriage and the second carriage across the build area, in which the first carriage may be independently movable with respect to the second carriage.

摘要： An additive manufacturing system including a housing configured to contain a powder bed of material, and an array of laser emitters having a field of view. The array is configured to melt at least a portion of the powder bed within the field of view as the array translates relative to the powder bed. The system further includes a spatter collection device including a diffuser configured to discharge a stream of gas across the powder bed, and a collector configured to receive the stream of gas and contaminants entrained in the stream of gas. The collector is spaced from the diffuser such that a collection zone is defined therebetween, and the spatter collection device is configured to translate relative to the powder bed such that the collection zone overlaps with the field of view of the array.

摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

摘要： The invention refers to a device for generative production of components, in particular by means of selective melting or sintering, comprising a light source for generating a light beam, a processing head that is either coupled to the light source by means of a beam guide, so that the light beam is guided to the processing head, or the light source is arranged directly on the processing head, so that a light beam can be directed from the processing head to a processing area, the processing head being mounted movably, so that the light beam can be directed to any desired location on the processing area. The invention is characterized in that several processing heads are provided for the respectively directing a light beam onto the processing area, and the processing heads are each arranged on a carriage that can be moved along a traverse. This allows powder to be melted or sintered simultaneous at several locations. Preferably, the processing heads are arranged on swivel arms. This allows a very simple and cost-effective design of the device.

摘要： Systems and methods additively manufacturing an object by applying heat to a first plurality of metallic particles in a powder bed using a first heat source, wherein the first heat source is one of multiple heat sources configured into an array, and the first heat source generates a first melt pool. Heat is simultaneously applied to a second plurality of metallic particles in the powder bed using a second heat source of the multiple heat sources in the array to generate a second melt pool. The first plurality of metallic particles are separated from the second plurality of metallic particles by a distance, wherein the distance and an amount of heat from each heat source is controlled to generate a combined melt pool that is larger in size and encompasses the first and second melt pools. The combined melt pool is allowed to solidify to form the object.

摘要： A method of manufacturing a three-dimensional object from a powder to form each layer of the object. The method includes the steps of driving a powder distribution sled in a first direction to distribute a layer of powder; driving a print sled in the first direction; driving the print sled and the powder distribution sled in a second direction; preheating the layer of powder by activating multiple radiation sources during various ones of the driving steps; during some of the driving steps, depositing a pattern of fluid onto the layer of powder; and sintering the powder on which fluid was deposited only in the second direction, by activating the at least one radiation source assembly during various ones of the driving steps in that direction. Repeating the above steps to distribute the next layer of powder.
