Abstract: Systems and methods for designing and manufacturing an additive manufacturing (AM) model. A method includes computing a wedge plane and initial toolpath for an AMmodel based on a breaking angle. The method includes trimming an excess toolpath of the AM model using a breaking plane. The method includes building the toolpath along the normal of a first layer and trimming based on a next layer. The method includes building a next wedge of the toolpath in the direction of a wedge plane used to trim a previous wedge The method includes storing the toolpath.

Abstract: A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The generated instructions specify how a deposition head and/or a build plate of the 3D printer moves relative to each other to build an article on the build plate such that material outputted from the deposition head is deposited in successive layers in a build direction. The processor may receive a user selection of a spiral pattern selection. For at least portions of each layer of at least a portion of the article, the generated instructions specify that the deposition head continuously deposits material in a spiral pattern between radially outward and radially inward portions of the article.
