Novel method for the 3D shaping of different materials using a high-pressure abrasive water jet is presented in the paper. For the steering movement process of the jet, a principle similar to the raster image way of record and readout was used. However, respective colors of pixels of such a bitmap are connected with adequate jet feed rate that causes erosion of material with adequate depth. Thanks to that innovation, one can observe spatial imaging of the object. Theoretical basis as well as spatial model of material shaping including steering program is presented in. There are also presented experimental erosion results as well as practical examples of the object’s bas-relief made of metal.
