Systems and methods of additive structure establishment

Abstract

Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a metal deposition device (MDD) is configured to deposit a metal material during an additive manufacturing process. A controller is operatively coupled to the MDD and is configured to command the MDD to deposit the metal material on a base to form a contour of a part. The controller is configured to command the MDD to deposit the metal material on the base to form an infill pattern within a region outlined by the contour. The infill pattern is a wave shape having a wavelength. The controller is configured to command the metal deposition device to fuse the infill pattern to the metal contour at crossover points, where the infill pattern meets the contour, by applying energy at the crossover pointsand reducing a deposition rate of the metal material at the crossover points to prevent distorting the contour.

Description

[0001] Cross Reference / Incorporation by Reference to Related Applications [0002] This US patent application claims priority and benefit to US Provisional Patent Application Serial No. 62 / 592,045, filed November 29, 2017, the entire disclosure of which application is incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to systems and methods related to additive manufacturing, and more particularly to additive manufacturing structure building techniques. Background technique [0004] Conventionally, additive manufacturing processes are capable of producing near-net-shape parts at relatively low deposition rates, where each part is built layer by layer. However, build times can be lengthy, and existing build technologies may not be sufficient for additively manufacturing certain types of parts (e.g., tools). Contents of the invention [0005] Embodiments of the invention include systems and methods related to additive manuf...
