摘要
Three-dimensional objects are built up in layers by putting down a layer of a particulate material A and selectively adding a material B, depending on which parts of the layer are to be hardened. The material B is applied by a row of nozzles or a slit-shaped exit which extends over the entire width of the working area and which is traversed linearly over the layer of the material A.
