A device and method for the controlled processing of at least one workpiece (1), comprising a workpiece carrier (2) on which at least one workpiece receptacle (2.1) is present remote from a rotary shaft (2.0), at least one processing unit (3) and at least one inspection unit (4), which are offset relative to the rotary shaft (2.0) by an angular distance (β.sub.n) from one another, are each arranged so that they can be adjusted and moved in a translational manner radially with respect to the rotary shaft (2.0), so that a processing beam (E) and an inspection beam (P), offset relative to one another by the angular distance (β.sub.n), describe the same spiral-shaped movement path (S) relative to the workpiece carrier (2), and the inspection results derived at an inspection point (P.sub.P) are used to control process parameters in order to change the effect of the processing beam (E).

The invention relates to a method for providing control data for an additive manufacture device, having: a first step (S1) of accessing model data: a second step (S2) of generating a data model in which a construction material layer region (51) to be solidified during the production of an object section is specified for a construction material layer, wherein the region (51) to be solidified is divided into a first sub-region (51a) and a second sub-region (51 b), and a respective solidification scan of the region (51) locations to be solidified is specified in a data model, said scan solidifying the construction material, and a repeated scan is specified at the locations of the second sub-region (51b) but not at the locations of the first sub-region (51a), the energy input parameter during the repeat scan being measured such that the temperature of the construction material lies above a melting temperature; and a third step (S3) of providing data models generated in the second step (S2) as control data for integrating into a control data set.

The color of object data that indicates the shape and the color of an object is reproduced faithfully when modeling an object. A model is formed by discharging droplets having the same color from droplet discharging units onto a medium, based on the same reference signal. Colorimetry is performed on the model, and a first-portion and a second-portion having a color with a higher density are specified. The liquid amount of droplets per unit area to be discharged from droplets discharging units that formed the first-portion and the liquid amount of droplets per unit area to be discharged from droplets discharging units that formed the second-portion are adjusted such that a difference in density of colors to be reproduced decreases. The object is modeled by repeating processing for discharging droplets from the droplet discharging units based on the object data.

Disclosed is a method for providing control data for an additive manufacture device having a first step of accessing model data, and a second step of generating a data model in which a construction material layer region to be solidified during the production of an object section is specified for a construction material layer. The region to be solidified is divided into a first sub-region and a second sub-region, and a respective solidification scan of the region locations to be solidified is specified in a data model. The scan solidifying the construction material, and a repeated scan, is specified at the locations of the second sub-region but not at the locations of the first sub-region. The energy input parameter during the repeat scan is measured such that the temperature of the construction material lies above a melting temperature. The method further includes a third step of providing data models generated in the second step as control data for integrating into a control data set.
