Abstract (en)
[origin: WO2019086250A1] The invention relates to a method for measuring a base element (13), particularly a substrate (13a) or a preform (13b), of a construction cylinder arrangement (11), the construction cylinder arrangement (11) being arranged on a machine (1) for the additive manufacturing of three-dimensional objects (2) by sintering or melting a powdery material (6) using a high-energy beam (16), in which the base element (13) can be moved by means of a piston (12) in the substantially cylindrical base body (14) of the construction cylinder arrangement (11), a measurement pattern (50) is produced from laser light that illuminates at least part of the base element (13), for measuring the base element (13), and sites of incidence (A1, A2) of the laser light are observed and evaluated with a camera (21), resulting in the determination of measuring data about the base element (13), comprising position information and/or orientation information and/or information about the three-dimensional shape of at least part of the surface (01-03) of the base element (13). Said method is characterised in that the measurement pattern (50) is produced from laser light by deflection of a laser beam (24) of a measuring laser (23) by a scanner optical system (19) such that differently deflected laser beams (24a) are produced and the deflected laser beams (24a) are oriented at least towards the part of the base element (13), and in that the camera (21) is arranged in a laterally offset manner in relation to the deflected laser beams (24a). The invention provides a method for measuring a base element, which is simple, can be used in a flexible manner, and only requires a small amount of space in the processing chamber.
