摘要： In a three-dimensional printing method example, a liquid functional agent is selectively applied. The liquid functional agent includes i) an energy source material or ii) an energy sink material. A metallic or ceramic build material is applied. The liquid functional agent is selectively applied any of before the metallic or ceramic build material, after the metallic or ceramic build material, or both before and after the metallic or ceramic build material. The liquid functional agent patterns the metallic or ceramic build material to form a composite layer. At least some of the metallic or ceramic build material is exposed to energy. A reaction involving i) the energy source material or ii) the energy sink material is initiated to alter a thermal condition of the composite layer.

摘要： Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of ceramic materials and components with a thickness greater than three millimeters (3 mm). A sulfur-free 3D printable formulation comprises a liquid inorganic polymer resin using Stereolithograpy (SLA) printers and Digital Light Processing (DLP) curing of the polymer resin via the chemical bonding of the materials rather than sintering. Thus, the process has shorter manufacturing intervals, significantly lower energy use and produces larger scale ceramic components having less linear shrinkage, less mass loss and high ceramic yield with no corrosive sulfur compounds present in the ceramic component.

摘要： The present invention relates to a method for preparing a fully ceramic capsulated nuclear fuel material containing three-layer-structured isotropic nuclear fuel particles coated with a ceramic having a composition which has a higher shrinkage than a matrix in order to prevent cracking of ceramic nuclear fuel, wherein the three-layer-structured nuclear fuel particles before coating is included in the range of between 5 and 40 fractions by volume based on after sintering. More specifically, the present invention provides a composition for preparing a fully ceramic capsulated nuclear fuel containing three-layer-structured isotropic particles coated with the substance which includes, as a main ingredient, a silicon carbine derived from a precursor of the silicon carbide wherein a condition of ΔLc>ΔLm at normal pressure sintering is created, where the sintering shrinkage of the coating layer of the three-layer-structured isotropic nuclear fuel particles is ΔLc and the sintering shrinkage of the silicon carbide matrix is ΔLm; material produced therefrom; and a method for manufacturing the material. The residual porosity of the fully ceramic capsulated nuclear fuel material is 4% or less.
