A method for calibrating an apparatus for producing an object by additive manufacturing, the apparatus including a process chamber for receiving a bath of material to be solidified by exposure to electromagnetic radiation, a support for positioning the object in relation to the surface level of the bath of material, and a solidifying device for solidifying a selective layer-part of the material on the surface level by electromagnetic radiation, the method including controlling the solidifying device to make a first test mark at a first delay setting, controlling the solidifying device to make a second test mark at a second delay setting different from the first delay setting, and determining a delay setting based on at least the first test mark and the second test mark.

Method for calibrating an apparatus for producing an object by means of additive manufacturing, and apparatus for the method

The invention relates to a method for manufacturing an object from a material by means of additive manufacturing using a plurality of solidifying devices for solidifying said material in stacked layers by means of electromagnetic radiation. Said method comprises the step of defining, by a data processing unit, at least two solidifying device allocations. In each of said solidifying device allocations said plurality of solidifying devices are allocated to respective parts of said layer such that said parts cover said layer. The method further comprises calculating, by said data processing unit, for each of said at least two solidifying device allocations, respective allocated part manufacturing times representing times for each of said plurality of solidifying devices for solidifying said respective allocated part of said layer, wherein said calculating takes into account an expected disturbance area from solidifying said material by one of said plurality of solidifying devices, wherein said disturbance area relates to at least an expected fume above said layer. The data processing unit then determines the manufacturing throughput time, and selects a definite allocation.
