摘要： A system/method for converting a drawing into a model; slicing the model into a plurality of layers; creating a plurality of deposition schedules for the layers, wherein the deposition schedules correspond to the layers; generating a plurality of coordinate sets for the layers, wherein the coordinate sets correspond to the layers, wherein each of the coordinate sets includes a set of start coordinates and a set of end coordinates; selecting a plurality of features from a library for the layers; generating a program based on the features; outputting the program in a delimited format; running a simulation of a deposition based on the program in the delimited format; determining whether a result of the simulation is acceptable based on a parameter; and requesting an additive manufacturing machine to produce a workpiece responsive to the result being acceptable based on the parameter, wherein the workpiece is depicted in the drawing.

摘要： Provided is a fluid-cooled melting tool that can be used in methods and systems for manufacturing objects by additive manufacturing techniques, especially titanium and titanium alloy objects. In some configurations, the melting tool is configured to be a plasma transferred arc (PTA) torch and the deposition rate can be increased by increasing the flow rate of electric charge through the electrode made possible by the dual circuit cooling design of the torch. The fluid-cooled melting tools provided herein exhibit stable and repeatable PTA characteristics over wide range of current including current of 400 amps or more, whether pulsed or non-pulsed, and plasma gas flow inputs.

摘要： Provided are systems and methods for regulation of mass flow and monitoring of volumetric flow, for regulation of volumetric flow and monitoring of mass flow, and for regulation of both mass and volumetric flow of gas to a plasma torch for wire-plasma arc additive manufacturing processes, and methods for manufacturing metal objects by additive manufacturing using one or more of the systems.

摘要： A system/method for executing a program accessing a plurality of subroutines/libraries; invoking a first subroutine providing the program with axis data having offset values in accordance with a workpiece coordinate system; invoking a second subroutine providing the program with geometric data about a geometric of an additive manufacturing tool and setting a tool offset point of the tool at a distance above a substrate surface; receiving a workpiece identifier from an HMI; invoking a third subroutine providing the program with rapid plasma deposition part programming instructions and rapid plasma deposition features from one of the libraries based on the workpiece identifier; invoking a fourth subroutine verifying the instructions and the rapid plasma deposition features; and invoking a fifth subroutine enabling the program to request an additive manufacturing system to deposit a layer on the substrate surface by the additive manufacturing tool via the additive manufacturing process.
