摘要：Reproduction of hand crafted 3D shape geometry is an important industrial concept design step employed for items ranging in size and function. Adding surface art work would extend concept design to include essential product information. This paper describes an equipment and workflow implementation for simultaneously reproducing both 3D shapes and art work. The handcrafted shape is laser digitized to obtain the XYZ geometry coordinates plus the surface gray level. The resulting point cloud is processed and converted to an STL file for plastic rapid prototyping, while the surface gray level information is resampled to fit the smoothed surface and match the reproduction ink jet printing system resolution. Developed software automatically calculates the dot pattern to reproduce the art work onto the correct prototyped surface location. An actual sample produced using the system is shown.
