摘要： A method is disclosed for manufacturing a part via an additive manufacturing process. A solution is used which has a volatile component within which is suspended particles of a powdered material. The solution is heated until it at least one of begins boiling or is about to begin boiling. The heated solution is then deposited at least at one location on a substrate to help form a layer of the part. The volatile component then evaporates, leaving only the particles of powdered material. The particles are then heated to the melting point. The deposition and heating operations are repeated to successively form a plurality of layers for the part. The evaporation of the volatile component helps to cool the part.

摘要： The present disclosure relates to a system for performing an Additive Manufacturing (AM) fabrication process on a powdered material, deposited as a powder bed and forming a substrate. The system makes use of a laser for generating a laser beam, and an optical subsystem. The optical subsystem is configured to receive the laser beam and to generate an optical signal comprised of electromagnetic radiation sufficient to melt or sinter the powdered material. The optical subsystem uses a digitally controlled mask configured to pattern the optical signal as needed to melt select portions of a layer of the powdered material to form a layer of a 3D part. A power supply and at least one processor are also included for generating a plurality of different power density levels selectable based on a specific material composition, absorptivity and diameter of the powder particles, and a known thickness of the powder bed. The powdered material is used to form the 3D part in a sequential layer-by-layer process.

摘要： The present disclosure relates to a system for performing an Additive Manufacturing (AM) fabrication process on a powdered material (PM) forming a substrate. The system uses a first optical subsystem to generate an optical signal comprised of electromagnetic (EM) radiation sufficient to melt or sinter a PM of the substrate. The first optical subsystem is controlled to generate a plurality of different power density levels, with a specific one being selected based on a specific PM forming a powder bed being used to form a 3D part. At least one processor controls the first optical subsystem and adjusts a power density level of the optical signal, taking into account a composition of the PM. A second optical subsystem receives the optical signal from the first optical subsystem and controls the optical signal to help facilitate melting of the PM in a layer-by-layer sequence of operations.

摘要： A system is disclosed for performing an Additive Manufacturing (AM) fabrication process on a powdered material forming a substrate. The system may make use of a diode array for generating an optical signal sufficient to melt a powdered material of the substrate. A mask may be used for preventing a first predetermined portion of the optical signal from reaching the substrate, while allowing a second predetermined portion to reach the substrate. At least one processor may be used for controlling an output of the diode array.

摘要： Systems and methods are disclosed for manufacturing a three dimensional (3D) part. In one implementation a system in accordance with the present disclosure may make use of an additive manufacturing (AM) subsystem for performing an AM operation to form the 3D part. The 3D part may be formed using a plurality of distinct material layers layered one on top of another. The system may also involve at least one of a laser peening (LP) subsystem and a High Velocity Laser Accelerated Deposition (HVLAD) subsystem. The LP subsystem may be used for laser peening a selected subquantity of the layers, to impart improved hardness to the selected subquantity of the layers and/or to the overall 3D part. The HVLAD subsystem may be used to bond at least one of the material layers to a previously laid down one of the material layers.

摘要： The present disclosure relates to a method of producing a product through additive manufacturing with heat treatment. The method involves using a fusing beam to melt powder particles disposed on a substrate, where the fusing beam is impressed with a two dimensional pattern containing image information from a first layer to be printed. The fused powder particles are then heat treated with a beam impressed with an additional two dimensional pattern. The additional two dimensional pattern has image information from the first layer to achieve heat treatment of the product. The heat treatment is completed prior to laying down additional new layers of material. The heat treatment is an annealing operation. The method may further involve providing a new layer of powdered material on top of the layer of fused powder particles subsequent to the heat treatment, and repeating the melting and heat treating operations in a layer-by-layer fashion using the two dimensional pattern and the additional two dimensional pattern, until the part is completed.
