摘要： A method for additively manufacturing a workpiece having lateral workpiece dimensions includes obtaining a first data set defining the workpiece in layers arranged on top of the other. The method includes providing a manufacturing platform having lateral platform dimensions that are greater than the lateral workpiece dimensions. The method includes providing a structuring tool movable relative to the manufacturing platform. The method includes selecting an individual manufacturing region on the manufacturing platform. The method includes obtaining a second data set that represents individual layer deformations that are dependent on the selected manufacturing region. The method includes producing a defined material layer of the workpiece in the manufacturing region by controlling the structuring tool using the first and second data sets. The method includes repeating the producing in order to produce further defined material layers one on top of the other using the first data set and the second data set.

摘要： A method for correcting deviations in a production process of an article, including: a) measuring surface coordinates of a first article, b) representing, in three dimensions, real measurement values from measuring the surface coordinates with a display apparatus that is fastenable or fastened to a user's head, c) representing, in three dimensions, a predefined model of the article using the display apparatus, d) comparing the predefined model to the point cloud or the point mesh, e) selecting at least one region from the point cloud or the point mesh which deviates from the predefined model, f) manipulating this region of the point cloud or the point mesh by means of the gesture or head movement control such that the point cloud or the point mesh in this region is matched to the predefined model, or approximated to the predefined model, or moved beyond the predefined model, g) transmitting at least one value of a deviation between the point cloud or the point mesh and the point cloud/point mesh obtained by manipulation to a production machine or a machine for shaping tool production, or transmitting the point cloud/point mesh obtained by manipulation to the production machine or to the machine for shaping tool production, h) producing a further article in the production machine or producing or post-processing of a shaping tool for producing the further article, wherein the deviation is corrected or compensated, or based on the point cloud/point mesh obtained by the manipulation.
