Popis: PurposeAims to develop a greyscale “painting system” by enabling the physical reproduction of digital texture maps on arbitrary 3D objects selectively exposing “pixels” of photographic emulsion with a robot mounted light source.Design/methodology/approachAfter reviewing existing methods of “decorating” 3D components, the properties of photographic emulsion are introduced and the nature of the rendering process' pixels discussed. A proposed path planning algorithm, used to derive both the robot's movement and the exposure times directly from a VRML representation, is then presented.FindingsResults obtained from successfully rendering images on the surface of a test object are presented.Research limitations/implicationsLimitations of current system include the overall process time and the inability to handle objects with concave geometry.Originality/valueThe system requires no bespoke production tooling and fills an automation gap in rapid prototyping and manufacturing technology that is currently occupied by hand painting.
