  • Pre-fabricated supports, a system for additive manufacturing a three-dimensional object, and a related method
    Patent number: 11207840
    Abstract: A system for additive manufacturing a three-dimensional object includes pre-fabricated supports arrangeable to support the three-dimensional object during additive manufacturing; and a computer configured to at least: access a computer geometric model of the three-dimensional object, and geometric parameters of the pre-fabricated supports; and generate an arrangement of the pre-fabricated supports with respective coordinates in a coordinate system, to support the three-dimensional object in the coordinate system during additive manufacturing, the computer being configured to generate the arrangement based on the computer geometric model of the three-dimensional object and the geometric parameters of the pre-fabricated supports, the computer being configured to generate different arrangements of the pre-fabricated supports for different three-dimensional objects having different computer geometric models.
