1. Method for producing a three-dimensional body, wherein the production of the three-dimensional body is carried out layer-wise, the method comprising:
- selectively depositing two different materials in each layer to follow an exterior contour of the three-dimensional body in said layer, a first material of the different materials being a release material and a second material of the different materials being a building material for building-up the three-dimensional body, wherein, at first, the release material is selectively deposited in a shape of a line to form a thin-walled shell around the exterior contour of said three-dimensional body in the respective layer, whereafter the building material is deposited to fill remaining areas surrounded by the shell.

Abstract
The present invention relates to a method for making a three-dimensional body, the construction of which is realised in layers by a purposeful application of material. According to the invention, two different materials are applied to each layer. One is purposeful applied in line along the outer edge of the three-dimensional object in the corresponding section plane, the remaining surfaces being filled with the second material.

17. Method for producing a three-dimensional body, wherein the three-dimensional body is divided into layers and produced layer-by-layer, the method comprising the following sequential steps for building each said layer:
-
depositing a first material to form a line-shaped shell defining a boundary of the three-dimensional body in said layer;
depositing a second material different from the first material, wherein the second material deposited in an area surrounded by the line-shaped shell is for building-up the three-dimensional body in said layer and the second material deposited outside the area surrounded by the line-shaped shell forms supporting material.
