Application: Method and apparatus for three-dimensional fabrication (Patent ID: US20230373156A9)
The patent filed by Carbon Inc. describes a method for forming a three-dimensional object using a carrier, build plate, and a semipermeable member. The process involves filling a build region with a polymerizable liquid, irradiating it to produce a solid polymerized region while maintaining a liquid film release layer, and advancing the carrier to create subsequent build regions. The apparatus includes a support, carrier, build plate, liquid polymer supply, and radiation source, with the build plate being in fluid communication with a polymerization inhibitor source.
The method includes steps such as providing a carrier and build plate, filling the build region with a polymerizable liquid, irradiating the region to form a solid polymerized region, and advancing the carrier to create subsequent build regions. The apparatus consists of a support, carrier, build plate, liquid polymer supply, radiation source, and a polymerization inhibitor source within the semipermeable member. The resulting three-dimensional object can include structures like a microneedle array, showcasing the versatility of the method in creating complex objects.
