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.

Abstract: The invention is a method and device for producing three-dimensional objects, having a gradient of properties and multi-material objects, from powders. A method involves the selection of powders of various materials according to diameter, the successive application of layers of powder of a given thickness during the vertical displacement of a piston of a device build chamber with an object to be sintered, and the programmed selective sintering/melting of a given area in the plane of each layer. After sintering, piston is raised, unsintered powder is removed from a layer. The piston is then returned, and a layer of powder having a different diameter and being of a dissimilar material is applied and selectively sintered. When the object-sintering process is finished, the unsintered powder is removed from the build chamber, and the powders are separated according to diameter. The separated powders are returned to feed containers of device for re-use.

Abstract: A method and an apparatus for collecting a powdered material after a print job in powder bed fusion additive manufacturing may involve a build platform supporting a powder bed capable of tilting, inverting, and shaking to separate the powder bed substantially from the build platform in a hopper. The powdered material may be collected in a hopper for reuse in later print jobs. The powder collecting process may be automated to increase efficiency of powder bed fusion additive manufacturing.

Abstract: An additive manufacturing apparatus includes a nozzle body discharging a powder and a carrier gas from an opening, a powder supply supplying the powder and the carrier gas to the nozzle body, a flow rate adjuster provided in a supply path of the powder supply to cause a part of a flow of the carrier gas containing the powder to flow into a branch flow path branching from the supply path to adjust a flow rate of the carrier gas containing the powder to be supplied to the nozzle body, and the branch flow path connected to the flow rate adjuster. The branch flow path is connected to a flow path leading to the nozzle body and has a separator for separating the powder and the carrier gas. The carrier gas separated from the powder by the separator is supplied to the nozzle body through the branch flow path.

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.
