  • Bead-type additive manufacturing system and method
    Patent number: 11225026
    Abstract: A manufacturing system includes a printhead, at least one profilometer, and a control system. The printhead extrudes a material onto a substrate and forms a new bead during additive manufacturing of an in-work article. The profilometer moves with the printhead and measures an in-work cross-sectional profile of existing beads of the in-work article. The control system generates in-work profile data including the in-work cross-sectional profile at a plurality of in-work profile locations, and continuously compares the in-work profile data to reference profile data of a reference article. The reference profile data includes a reference cross-sectional profile at a plurality of reference profile locations. The control system adjusts, based on the profile comparison, one or more bead forming parameters and causes the printhead to form the new bead according to the bead forming parameters to reduce or prevent nonconformities associated with forming the new bead.
