Process for manufacturing by layers influence on the grain size

摘要

Method for layerwise production of a product comprising the following steps: a. applying a layer of a hardenable material, being adjustable, for example, parameters and layer thickness procedure layer material, b. selectively hardening the applied predetermined by the geometric data of the product being adjustable, for example, the type parameters procedure and level of energy, c layer areas. repeating steps a) and b) to be obtained as product geometry hardened material, d. removing the material uncured, characterized in that at least one process parameter is modified during the manufacturing process to influence the grain size generated during manufacture of the product in a first area of ​​the product to a second area of ​​the product, meaning grain size the size of crystals of a metal product.
