Abstract: A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

Abstract: Methods of precisely regulating a process gas flow through a process chamber of an additive manufacturing system and related systems. The methods include positioning a removeable flow rate sensor to measure an actual bulk flow rate of the process gas flow and controlling the process gas flow to a desired bulk flow rate. The methods also include measuring the actual bulk flow rate with the removeable flow rate sensor, separating the removeable flow rate sensor from the process chamber, and comparing the actual bulk flow rate to the desired bulk flow rate. The methods further include proceeding with the additive manufacturing process or performing a corrective action and subsequently proceeding with the additive manufacturing process.

Abstract: We describe a method for controlling an irradiation beam for irradiating a layer of raw material powder in an additive layer manufacturing process for producing a three-dimensional work piece, wherein the method comprises: depositing, with a layer depositing mechanism, a said layer of raw material powder on top of a carrier and/or on top of a preceding material layer on top of the carrier; and controlling the irradiation beam to irradiate at least a portion of the layer of raw material powder in an irradiation area when a distance between the irradiation area and the layer depositing mechanism is above a threshold distance, and wherein the threshold distance is dependent on (i) a speed of movement of the layer depositing mechanism, and (ii) a speed, vg, of a gas flow over the layer of raw material powder.
