Method and device for manufacturing three-dimensional bodies
First Claim
1. A device for producing three dimensional bodies of a large number of mutually connected layers of a particle shaped building material, and where the information of the appearance of each layer is achieved from a computer CAD-unit, comprising:
- applying essentially even particle layer of building material on a support base, arranging on a masking device a masking pattern in accordance with the information from the CAD-unit, which masking device is led over said particle layer, arranging a radiation producer over the masking device, whereby the particles which are not covered by the masking pattern are exposed for radiation and thereby are attached to each other, and removing the masking pattern from the masking device, and performing processing until the three dimensional body is produced.

Abstract
A method for producing three-dimensional bodies of a large number of mutually connected layers of a particle-shaped material such as a powder, and where the information of the appearance of each layer is achieved from a computer'"'"'s CAD-unit or similar. An essentially even particle layer (7) of building material is applied on a support base (6) and on a masking device (9) is arranged a masking pattern in accordance with the information from the CAD-unit, which masking device is led over said particle layer and close to it. A radiation producer (8) is arranged or is led over the masking device (9), whereby the particles which are not covered by the masking pattern are exposed for radiation and thereby are attached to each other. The masking pattern is removed from the masking device and new sequences in accordance with the above are carried through until the three-dimensional body (19) is produced.

5. A device for producing three dimensional bodies of a large number of mutually connectable layers of a particle shaped building material, and where the information about each layer'"'"'s appearance is achieved from an original, from a computer CAD-unit, comprising:
-
a spreading device arranged to distribute an essentially even particle layer on a support base, a developer is arranged to generate or apply a masking pattern in accordance with the original, from the CAD-unit, on a masking device, a radiation producer configured over the masking device, whereby the particles which are not covered by the masking pattern are exposed for radiation and thereby are connected to each other, and an eliminator arranged to remove the existing masking pattern on the masking device. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
