  • Method of making 3D printed objects by dispensing sequential layers of material
    Patent number: 11498268
    Abstract: This method describes techniques to create 3D parts by dispensing a liquid polymer or slurry in evenly delivered layers, which are exposed to light from a visual display screen before the print platform upon which it is being built is moved one-layer thickness away and the process is repeated. The process of dispensing the photosensitive material is via a pumped system through a metering device that discharges and levels the material. Multiple dispensing devices can be arranged in sequence to deliver different materials, either multiple photosensitive dispensing heads or alternative mechanisms such as robocasting, fused deposition modelling or inkjet in addition to a photosensitive deposition head.
