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： An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects.

摘要： The invention relates to a method for the additive manufacture of three-dimensional metallic components (12), said components (12) being built layer-by-layer or section-by-section under vacuum conditions by fusing a metallic material with the component (12) at a machining point by means of a radiation source with a high energy density. In order to keep the energy applied to the machining point by the radiation itself relatively low, the metallic material is supplied in the form of a wire (28) which is preheated under vacuum conditions before reaching the machining point.

摘要： An aluminum alloy precursor composition and method for fusion processing is provided which reduces hot cracking, improves compositional control, reduces porosity, and/or enhances the mechanical properties of the fusion processed article. The precursor material and fusion process using the same may be utilized for forming an article that meets compositional specifications for aluminum 6061 alloy, while minimizing defects and meeting desired strength and ductility requirements. The fusion process may include a leading energy beam for liquefying the precursor material to form a melt pool, and a trailing energy beam directed toward a trailing region of the melt pool. The trailing energy beam may be configured to enhance agitation and/or redistribution of liquid in the melt pool to prevent hot cracking, reduce porosity, or improve other characteristics of the solidified part. The method also may improve processing parameters, such as adjusting vacuum level to prevent volatilization of alloying elements.

摘要： A process and apparatus for free form fabrication of a three-dimensional work piece comprising (a) feeding raw material in a solid state to a first predetermined location; (b) depositing the raw material onto a substrate as a molten pool deposit under a first processing condition; (c) monitoring the molten pool deposit for a preselected condition; (d) comparing information about the preselected condition of the monitored molten pool deposit with a predetermined desired value for the preselected condition of the monitored molten pool deposit; (e) solidifying the molten pool deposit; (f) automatically altering the first processing condition to a different processing condition based upon information obtained from the comparing step (d); and repeating steps (a) through (f) at one or more second locations for building up layer by layer a three-dimensional work piece. The apparatus is characterized by a detector that monitors a preselected condition of the deposited material and a closed loop electronic control device for controlling operation of one or more components of the apparatus in response to a detected condition by the detector.
