摘要： Methods and systems for manufacturing a workpiece. The method described herein includes depositing at least a first sheet on a substrate, the first sheet comprising a first part region and a first support structure region separated at least in part by a first void space; and operably positioning a plate with respect to the first sheet so that the first void space forms a channel suitable for carrying a fluid.

摘要： A method for the manufacturing of an object. The method includes receiving a desired alloy composition for the object, depositing a plurality of foils in a stack to form the object, applying heat to the stack at a first temperature to bond the plurality of foils to each other, and applying heat to the stack at a second temperature to homogenize the composition of the stack. The homogenized stack has the desired alloy composition.

摘要： A method for the additive manufacturing of an object and a system for manufacturing an object. The method includes depositing a second foil sheet onto the first foil sheet, wherein the first foil sheet and the second foil sheet each comprise a structural layer, forming a layer stack comprising the first foil sheet and the second foil sheet, the layer stack comprising an object section and at least one support section configured to enclose the object section in the layer stack, and applying at least one of heat or pressure to opposite sides of the layer stack with a first plate and a second plate, wherein applying the at least one of heat or pressure increases the temperature of the layer stack to a temperature lower than the melting temperature of the structural layer, and the at least one of heat or pressure bonds the first foil sheet to the second foil sheet in the layer stack, the first plate and the second plate are in contact with the at least one support section, and the at least one support section is configured to conduct the at least one of heat or pressure through the layer stack to the object section.

摘要： A method for the additive manufacturing of an object and a system for manufacturing an object. The method includes depositing a first foil layer, the first foil layer including a first body section, a first support section connected to the first body section, and a second support section connected to the first body section; depositing a second foil layer, the second foil layer comprising a second body section, a third support section, and a fourth support section; aligning the second foil layer and the first foil layer; and applying at least one of heat and pressure to the first foil layer and the second foil layer to form the object comprising the first body section and the second body section.
