A method and apparatus used to produce control data for building up a product layer by layer using freeform sintering and/or melting with a high energy beam. The correspondingly controlled apparatus for production of the products is further disclosed. The high energy beam is applied under the guidance of the control data set. Before beginning the freeform sintering and/or freeform melting, a compensation data set and/or a compensation function to compensate for manufacturing related effects caused by the sintering and/or melting is determined. The control data set is based upon a product target geometry data set and the compensation data set and/or the compensation function.

Method and device use to produce a set of control data for producing products by free-form sintering and/or melting, in addition to a device for the production thereof

A method for making metallic or non-metallic products by freeform laser sintering, in which the products are fabricated from powdery material on a substrate plate in vertically additive, layer-by-layer fashion by means of a computer-controlled laser beam, characterized in that at least one support is fabricated between the substrate plate and the outer surface of the product, said support being connected via a predetermined breaking area with the outer surface of the product, wherein the predetermined breaking area is formed by reducing the strength of the support along the outer contour of the product.
