Abstract
Embodiments of the present disclosure are drawn to additive manufacturing methods. An exemplary method may include generating a tool path for forming a component via additive manufacturing, and assessing the tool path to identify a change in direction. The method may also include determining if the change in direction exceeds a predetermined angle, and adding a tangent arc to the tool path before the change in direction if the change in direction exceeds the predetermined angle.
Claims18
An additive manufacturing method, comprising:
- generating a tool path including a first direction and a second direction;
- assessing the tool path to determine if a change in direction in the tool path exceeds a predetermined angle;
- moving a nozzle of an applicator head in the first direction, wherein the nozzle is configured to deposit a heated material, and wherein the applicator head includes a roller;
- diverting the nozzle along a tangent arc while depositing the heated material prior to a change in direction of the tool path to the second direction in order to compensate for the change in direction of the tool path;
- and
- engaging the deposited heated material with the roller while moving the nozzle in the second direction of the tool path to move at least a portion of the heated material deposited along the tangent arc toward the second direction, wherein the second direction is different than the first direction.
