Abstract: A printing apparatus for printing a three-dimensional object. The printing apparatus includes an operative surface and a plurality of supply hoppers configured for dispensing a powder. The powder is configured to be melted by an energy beam. The supply hoppers are configured to form a plurality of vertically-aligned powder beds adjacent to one another on the operative surface simultaneously. An energy source is configured to emit an energy beam onto each powder bed simultaneously to melt or fuse a topmost layer of the powder bed onto an underlying powder bed layer or substrate.

Abstract: An apparatus is for forming powder, and includes an energy source for emitting at least one energy beam onto a workpiece, the energy beam being configured to melt the workpiece, at least in part, to form at least one pool of molten material on the workpiece. The apparatus is configured to exert a force on the workpiece causing at least a bead of molten material to be ejected from the pool and solidify to form a particle of powder.

Abstract: A method is for printing a certified part using a certified digital part file. The method has the following steps: a. Using a 3D printing apparatus and a certified digital part file to print a part according to a print process, the certified digital part file having geometry, parameters and a check data set, the check data set having criteria defining acceptable and non-acceptable levels of anomalies for successful printing of the certified part, b. During the print process, comparing print data generated by the apparatus with the check data set to indicate where a part of the printing process contains a non-acceptable anomaly. c. Where a non-acceptable anomaly is detected, using the apparatus to recover the print process by taking corrective action if possible to remove the anomaly or reduce the anomaly to an acceptable level or, where the print process is not recoverable, abandoning the print process.
