  • SEMI-PERMEABLE ELEMENT, USE THEREOF AND PREPARATION METHOD THEREFOR AND 3D PRINTING DEVICE
    Publication number: 20210291451
    Abstract: A semipermeable element for the penetration of 3D printing curing inhibitors. The semipermeable element has a pore density of 107-1011/cm2, and/or the pore diameter of 0.01 ?m-5 ?m. A usage of a semipermeable element, and manufacturing method thereof as well as a 3D printing apparatus. The semipermeable element has good permeability to the curing inhibitor, and simply introducing air can achieve the thickness of inhibited curing layer as required by the continuous manufacturing of the three-dimensional objects.

  • 3D printing apparatus and method
    Patent number: 11123920
    Abstract: A 3D printing apparatus with a radiation source, a workbench, and a liquid tank, wherein a workbench for supporting a three-dimensional object being constructed, and a liquid tank for containing a polymerizable liquid for constructing a three-dimensional object. The apparatus also includes a cover plate which is located in the liquid tank or on the top of the liquid tank; the radiation source irradiates from above the cover plate. The cover plate is an element transparent to the radiation source; and the lower surface of the cover plate is a covering surface which remains in contact with the polymerizable liquid during the printing process.

  • Honeycomb-shaped fuel assembly cooled by liquid chloride salt and reactor core using this assembly
    Publication number: 20200303082
    Abstract: A honeycomb-shaped fuel assembly cooled by liquid chloride salt adopts a honeycomb-shaped structure. A fuel coolant is a mixture of liquid three-phase chloride salt NaCl—KCl—MgCl2. Fuel is U3Si2 with an enrichment of 19.75% or 16.0%. The fuel assembly includes: fuel coolant channel pipelines which vertically penetrate and laterally merge, a fuel coolant contained in the fuel coolant channel pipelines, a fuel zone, upper and lower endcap, a top gas plenum, and upper and lower endcap. A reflector assembly adopts a honeycomb-shaped structure, including: reflector coolant pipes which are vertically penetrating; a reflector coolant contained in the reflector coolant pipes; a titanium reflector; and upper and lower endcaps. A control assembly and a safety assembly adopt a rod bundle structure using B4C with a natural enrichment of 10B as absorbers.
