Abstract: 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.

Abstract: A method of additively manufacturing a workpiece (22) from a powder material, comprises the steps of:



(a) providing

a device (15, 17) for receiving a powder bed (20) of the powdery material, in particular in a vacuum process chamber (11), and
a beam generator (12) adapted to direct an energy beam (13) to laterally different locations of the powder bed (20);


b) layer-by-layer application of the powdery material to the powder bed (20);
c) creating the workpiece (22) in the powder bed (20) layer by layer by selectively bonding the powdery material to the energy beam (13);
d) during the production of the workpiece (22), in addition to the workpiece (22), a cooling structure (30) is produced in the powder bed (20) by selective bonding of the powdery material to the energy beam (13), the cooling structure (30) being adapted to dissipate heat.

Abstract: A system includes an enclosed laser powder bed fusion (LPBF) containment volume. A powder drain is included below the containment volume configured to receive powder dropping from the containment volume by force of gravity. A valve below the powder drain is configured to allow passage with the valve in an open state of unfused powder from the drain into a powder collection volume separated from the containment volume by the valve, and prevent passage of powder from the drain into the collection volume with the valve in a closed state. A source of wetting agent is in fluid communication with the powder collection volume for capturing powder in the collection volume by wetting the powder. A moisture trap is operatively connected to the drain above the valve and is configured to capture moisture to prevent moisture from the collection volume migrating into the containment volume.

Abstract: A method and an apparatus pertaining to recycling and reuse of unwanted light in additive manufacturing can multiplex multiple beams of light including at least one or more beams of light from one or more light sources. The multiple beams of light may be reshaped and blended to provide a first beam of light. A spatial polarization pattern may be applied on the first beam of light to provide a second beam of light. Polarization states of the second beam of light may be split to reflect a third beam of light, which may be reshaped into a fourth beam of light. The fourth beam of light may be introduced as one of the multiple beams of light to result in a fifth beam of light.
