Automation




Concrete is the closest propolis equivalent human implemented product. Its aggregate can also be sourced locally. Construction 3D Printing (c3Dp) or 3D Construction Printing (3DCP) refers to various technologies that use 3D printing as a core method to fabricate buildings or construction components. Alternative terms for this process include "additive construction." "3D Concrete" refers to concrete extrusion technologies whereas Autonomous Robotic Construction System (ARCS), large-scale additive manufacturing (LSAM), or freeform construction (FC) refer to other sub-groups.

At construction scale, the main 3D-printing methods are extrusion (concrete/cement, wax, foam, polymers), powder bonding (polymer bond, reactive bond, sintering), and additive welding.

A number of different approaches have been demonstrated to date, which include on-site and off-site fabrication of buildings and construction components, using industrial robots, gantry systems, and tethered autonomous vehicles. Demonstrations of construction 3D printing technologies have included fabrication of housing, construction components (cladding and structural panels and columns), bridges and civil infrastructure, artificial reefs, follies, and sculptures.
