Abstract: Contour Crafting is a mega scale layered fabrication process which builds large scale three-dimensional parts by depositing paste materials layer by layer at unprecedented speed and with superior surface quality. This paper presents an overview of related research activities and the progress aimed at extending the technology to construction of residential housing units and civil structures.

Keywords: contour crafting; layered manufacturing; mega scale fabrication; cement extrusion; construction automation; house construction; lunar construction; residential housing; civil structures; material deposition.
