  • Patent number: 11945754
    Abstract: A method for forming a complex shape three-dimensional ceramic article by printing a first layer of a first material having a first fraction of first ceramic particles and a first fraction of a first polymeric ceramic precursor. A second layer is printed such that it is at least partially disposed on the first layer of a second material having a second fraction of second ceramic particles and a second fraction of a second polymeric ceramic precursor. A composite of the first layer and the second layer is heated at a temperature sufficient to decompose the first and second polymeric ceramic precursors and sinter the article. During the sintering process, the first and second layers with different fractions of ceramic particles undergo different degrees of shrinkage, resulting in a tuneable mismatch of the bilayer structure and accurately achieving a targeted geometry.

  • Patent number: 11407541
    Abstract: The present invention proposes a large industrial vacuum sealer system. The system comprises the following working steps: after materials are placed, a box base moves upwards to be jointed with a box cover in a sealing manner; the first valve 120 is switched on; a rotary vane pump starts roughly pumping the air; next, a roots pump starts working; when the pressure reaches a preset value, the first valve 120 is switched off; valves 110 and the second valve 130 are switched on; diffusion pumps start working; after the air is pumped out completely, all pumps stop working. A box body comprises the box cover and the box base, wherein the box body is fixedly mounted. The box base is driven by air cylinders to move along a rail. In the present invention, a light curtain sensor is mounted between the box cover and the box base.
