Abstract: A calibration method serves for calibrating a manufacturing device for additively producing a three-dimensional object by applying layer by layer and selectively solidifying a building material. The manufacturing device comprises at least two scanning units, each of which is capable of directing a beam to different target points in the working plane, which are located within a scanning region assigned to the respective scanning unit, wherein the scanning regions region of the at least two scanning units overlap in an overlap area. At least a first of the at least two scanning units is assigned a first monitoring unit whose monitoring region extends to a target point of the first scanning unit and its proximity, wherein a change of a position of the monitoring region is carried out as a function of a change of a position of the target point.

Abstract: Additive manufacturing, such as laser sintering or melting of additive layers, can produce parts rapidly at small volume and in a factory setting. To ensure the additive manufactured parts are of high quality, a real-time non-destructive evaluation (NDE) technique is required to detect defects while they are being manufactured. The present invention describes an in-situ (real-time) inspection unit that can be added to an existing additive manufacturing (AM) tool, such as an FDM (fused deposition modeling) machine, or a direct metal laser sintering (DMLS) machine, providing real-time information about the part quality, and detecting flaws as they occur. The information provided by this unit is used to a) qualify the part as it is being made, and b) to provide feedback to the AM tool for correction, or to stop the process if the part will not meet the quality, thus saving time, energy and reduce material loss.
