Abstract
The invention relates to a method and to a device for generating three-dimensional objects by means of a generative method. According to the invention, powdered material and binding agents are applied sequentially and electromagnetic waves are used to cure the binding agent so that the powdered material bonded with the binding agent forms the three-dimensional object. The electromagnetic waves used are RF radiation. As a result, a fast and uniform curing of the three-dimensional object is achieved.
Claims12
Method for the production of three-dimensional objects by means of a generative process in which a powdery material and binder are applied sequentially and the binder is cured by electromagnetic waves, so that the powdery material bonded by the binder forms the three-dimensional object,
- wherein RF radiation is used as electromagnetic waves.
Method for the production of a sand core or a sand mould, in which the sand core or the sand mould are either produced as a three-dimensional object, by bonding sand as powdery material by means of a binder to form a three-dimensional object, or the sand core or the sand mould is made by shooting into a mould, wherein a mixture of sand and binder is shot into the mould and the sand core or sand mould is cured by RF radiation.
Device for the production of three-dimensional objects by means of a generative method, comprising
- an application device for sequential application of powdery material
- an application device for the application of binder
- an RF generator to generate RF radiation, and
- two capacitor plates to apply the RF radiation to the applied mixture of powdery material and binder.
