摘要： Methods of manufacturing a manufactured component, additive manufacturing systems that perform the methods, and storage media that directs additive manufacturing systems to perform the methods. The methods include supplying a feedstock material along a scan path. The methods also include delivering, to an addition location, an amount of energy sufficient to form a melt pool of the feedstock material at the addition location. The methods further include, during the delivering the amount of energy, moving the addition location along the scan path to move the melt pool along the scan path and define a consolidated material track from the feedstock material. The methods also include determining that the melt pool is within a threshold proximity of a merge region and adjusting a process parameter value of the additive manufacturing system from a process parameter pre-merge-region value to a process parameter post-merge-region value that differs from the process parameter pre-merge-region value.

摘要： Methods of manufacturing a manufactured component, additive manufacturing systems that perform the methods, and storage media that directs additive manufacturing systems to perform the methods. The methods include determining a process parameter value and determining a spatial offset parameter value based upon the process parameter value. The methods also include forming the manufactured component utilizing the additive manufacturing system. The forming includes supplying a feedstock material, delivering, to an addition location, an amount of energy sufficient to form a melt pool of the feedstock material, and moving the addition location along a scan path to define a plurality of consolidated material tracks from the feedstock material. Each consolidated material track extends between a corresponding initiation location and a corresponding termination location, and a location of at least one of the corresponding initiation location and the corresponding termination location is based on the spatial offset parameter value.

The methods further include moving the addition location along the scan path to move the melt pool along the scan path and define a consolidated material track from the feedstock material. The delivering the amount of energy includes selectively varying the amount of energy as a function of position along the scan path to increase a uniformity of the consolidated material track and/or to increase a uniformity of a consolidated material layer that is partially defined by the consolidated material track.

摘要： An additive manufacturing device includes a stage configured to support a substrate. The device also includes a printhead disposed above the stage. The printhead is configured to heat a build material to a molten build material and to deposit the molten build material on the substrate in the form of droplets to fabricate an article. The device also includes a controlled heating and ablation system disposed proximal the printhead. The controlled heating and ablation system is configured to heat the substrate and ablate oxides on a surface of the substrate.

摘要： A method for improving deposition of metal powder in a three-dimensional printing process, the method comprising: (a) irradiating a metal powder-polymer matrix flexible film using a heat source to vaporise the polymer and melt the metal particles together to form a 2D layer; (b) placing the same or a new layer of the metal powder-polymer matrix flexible film on top of the previous 2D layer, and (c) repeating the application of the heat source for a number of cycles to produce the desired 3D product; wherein the heat source has a focal plane that converges beyond the metal powder-polymer matrix flexible film.
