A method for manufacturing a target material is provided and includes installing a substrate, providing a raw material powder to the substrate, melting the raw material powder on the substrate by a laser, and repeating the step of providing the raw material powder to the substrate to melting the raw material powder on the substrate by the laser to form a target material and rapidly cooling the formed target material. As such, the target material is produced by the method of lamination manufacturing via the rapid cooling property, so as to avoid the problems of high cost, long man-hours and poor quality of the target material in the conventional techniques.

An improved method and apparatus for adding a new layer to a stack of previously processed layers. In an example, a method is provided for mounting the previously processed layer on a build platform, mounting the new layer on a substrate, aligning the new layer with the previously processed layer, moving the new layer and the previously processed into contact with one another, and applying energy to the new layer from an energy source through the substrate to simultaneously process the new layer and bond the new layer to the previously processed layer to form a bonded processed multilayer stack on the build platform. A flexible compliant pressure conveyance media is moved into contact with the substrate to apply pressure to the new layer while the energy is being applied.

An improved apparatus and method provide conditioning to a powder deposited on a substrate (e.g., a web), for example, by wetting the powder in a 3D printing apparatus. To achieve this in an exemplary implementation, a wetting apparatus is located between a powder dispenser and at least one top calendering roller in a direction of movement of the substrate, wherein the wetting apparatus is configured to apply a wetting agent to the powder on the substrate before the powder passes through the calendering roller. The wetting agent is comprised of a material which increases cohesiveness of the powder to prevent the powder from adhering to the top roller. In a particular implementation, the wetting agent is steam confined to an area of the substrate where the powder passes through the wetting apparatus, without wetting other areas of the substrate which are not in the wetting apparatus.

A method of printing a 3D printing a photopolymer composite material includes providing a resin premix material including an acrylate monomer or an acrylate oligomer, an inorganic hydrate, a reinforcing filler, a co-initiator, and an ultraviolet (UV) initiator. A thermal initiator is mixed with the resin premix to form a photopolymer composite resin. The photopolymer composite resin is repeatedly extruded and dual-cured by a 3D printing system to create a photopolymer composite material. The 3D printing system includes a control system, a mixing system, a feeding system in fluid communication with the mixing system, a light curing module controlled by the control system, and a printing head controlled by the control system.
