Method and device for computer-assisted fabrication of three-dimensional bodies for temperature control workpieces

摘要

The method involves defining body cells (510, 520) with different permeabilities for a preset tempering medium. The body cells are joined in a group, which is suitable for obtaining a three-dimensional body, where the group forms a desired flow path of the tempering medium in the three-dimensional body. Layer data of the three-dimensional body is generated. Porosities of the body cells are adjusted, such that the body cells exhibit the permeabilities for the tempering medium. Independent claims are also included for the following: (1) a computer program having instructions to perform a method for computer-assisted production of a three-dimensional body (2) a data carrier having instructions to perform a method for computer-assisted production of a three-dimensional body (3) a free-form fabrication-system including a computer system.
