Abstract The Sand-Painter project addresses the problem of pointwise deposition of multi-material powders in layered manufacturing. This approach is key to the development of selective aggregation processes capable of producing functional prototypes with internal sub-structures not achievable by any of the extant layered manufacturing processes. The solution adopted for this project is an automated version of the ancient Native American art of sand painting. Preliminary results pertaining to powder flow and deposition characterization represented. A proof of concept multi-material deposition process was demonstrated. Keywords: Sand painting, layered manufacturing, SLS, 3D-Printing, selective aggreg tion, multi-material, multi-moded structures, functionally graded materials., mechatronics.
