3d printer build plate assembly with lighting panel and gas flow
A recently granted patent (Publication Number: US11993015B2) discloses a method for forming three-dimensional objects using a carrier and an optically transparent member with a build surface. The process involves filling a build region with a polymerizable liquid, irradiating the region with light to form a solid polymer, and advancing the carrier to create the object. The optically transparent member includes a build plate with a lighting panel, a planar screen or base, and a flexible, gas-permeable sheet. This configuration allows for gas flow to the build surface, ensuring proper formation of the object.
Furthermore, the method includes steps to maintain a dead zone of polymerizable liquid in contact with the build surface and a gradient of polymerization zone between the dead zone and the solid polymer. By incorporating a semipermeable member and feeding an inhibitor of polymerization, the process ensures the proper maintenance of these zones. Additionally, the method involves vertically reciprocating the carrier to enhance the refilling of the build region with the polymerizable liquid, with specific parameters for the distance of travel and speed of the reciprocating motion. Overall, the patent outlines a detailed and innovative approach to creating three-dimensional objects using a unique build plate design and precise control over the polymerization process.
