Abstract:
In a process for manufacturing a three-dimensional object (6), the object is generated by successively consolidating individual layers (6a, 6b, 6c, 6d, 6e) of liquid or powdery material (3) by electromagnetic radiation (8, 10). A supporting skeleton (20, 21) for supporting the object (6) is consolidated together with the object. The supporting skeleton (20, 21) is subdivided in three dimensions into an inner core area (22) and into an outer wrapping area (23). Radiation is differently regulated to generate different properties in the two areas.
