摘要： Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform.

摘要： Methods and apparatus for processing a substrate are provided herein. For example, an RF power delivery compensation circuit comprises a first input configured to receive an RF forward power from an RF power source connected to a processing chamber and a second input configured to receive an RF delivered power from a matching network connected between the RF power source and the processing chamber. The RF power delivery compensation circuit calculates an RF forward power compensation factor based on the RF forward power and the RF delivered power for adjusting the RF forward power delivered to the processing chamber during operation.

摘要： A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

摘要： An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects. A side removal mechanism of the build chambers of the apparatus improves handling and efficiency for printing large and heavy objects. Use of a wide range of sensors in the apparatus and by the method allows various feedback to improve quality, manufacturing throughput, and energy efficiency.

摘要： A method of manufacturing a turbo-machine impeller, which includes a hub and a plurality of blades, using powder material in an additive-manufacturing process. The method includes: applying energy to the powder material by way of a high energy source, and solidifying the powder material. At least one bulky portion of the hub is irradiated such that the powder material solidifies in a lattice structure surrounded by an outer solid skin structure enclosing the lattice structure.

摘要： An additive manufacturing method for making a metal matrix composite component includes melting a powdered mixture with an electron beam. The powdered mixture comprises powdered tungsten carbide in an amount of 45 wt % to 72 wt % of the powdered mixture and a powdered binder in an amount of 28 wt % to 55 wt % of the powdered mixture. The powdered binder comprises boron, silicon, and nickel.

摘要： A method of fabricating plates of super-hard material and cutting techniques suitable for such a method. A method of fabricating a plate (14) of super-hard material, the method comprising: • providing a substrate (4) have a lateral dimension of at least 40 mm; • growing a layer of super-hard material on the substrate (4) using a chemical vapour deposition process; and • slicing one or more plates (14) of super-hard material from the substrate using a collimated cutting beam (8), the or each plate of super-hard material (14) having a lateral dimension of at least 40 mm, wherein the collimated cutting beam (8) is collimated with a half angle divergence of no more than 5 degrees.
