Hydro-jetting method of bas-relief shaping

The paper presents a novel method for the 3D shaping of different materials using a high-pressure abrasive water jet and a flat target image. For steering movement process of the jet a principle similar to raster image way of record and readout was used. However, respective colours of pixel 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 of material shaping and experimental stand including steering program are presented in. There are also presented methodical and some experimental erosion results as well as practical examples of object's bas-relief made of metal.
