Abstract (en)
[origin: CA3053691A1] The invention relates to a method for controlling a jetting system (20), the jetting system (20) being used in a device (10) for the additive manufacturing of three-dimensional workpieces and comprising at least three jetting units (22a-d, 50), the method comprising the following steps: a) defining a jetting region (30a-d) for each of the jetting units (22a-d, 50), the jetting regions (30a-d) each comprising a portion of a jetting plane (28) which extends parallel to a support (16) of the device (10), and the jetting regions (30a-d) being defined such that they overlap in a common overlap region (34); b) jetting a raw material powder layer on the support (16) to produce a workpiece layer; c) arranging a further raw material powder layer on the already jetted raw material powder layer to produce a further workpiece layer. d) The invention also relates to a device for performing this method.
