Robotic Construction by Contour Crafting: The Case of Lunar Construction

Abstract

Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

From Parametric Design to Contour Crafting Technics: A Lab for Algo+Ritmo, a Brazilian Research Group

“…A calibragem, o material escolhido, velocidade de impressão, o nivelamento da superfície de contato, entre outras configurações, são essenciais para que o resultado final ideal seja atingido. Diversos materiais vêm sendo testados de maneira bem-sucedida, como por exemplo concreto, cerâmica, terra, polímeros, vidro, entre outros (Khoshnevis, 2006), (Leach et al, 2012;Fernandes;Feitosa, 2015;Kontovourkis, Tryfonos, 2018).…”

Conventional Construction and 3D Printing: A Comparison Study on Material Cost in Jordan

“…e contour crafting (CC) construction process was developed to change the construction from the conventional method to a layer-by-layer method ( Figure 2) [9]. CC is a layered construction technology developed by Dr. Behrokh Khoshnevis to automate the construction of structures of a complete house including electrical, plumbing, drywall, and insulation [10]. CC lowers the construction cost, increases the construction speed, gives more flexibility for architectural design, and provides safe and friendly environment.…”

Automatic Construction by Contour Crafting Technology

“…The range of the application of this technology has also reached the aeronautics industry. NASA is using this technology to build essential tools for astronauts, such as landing pads, shelters, protection walls, reflecting walls, probes landing places and paths [10].…”
