One day robotic construction will liberate home building, enable many more forms, challenge the high cost and make construction greener. Various materials can be used to manufacture beautiful ceilings, Constros path is to 3D print gypsum - a material that is fully recyclable, non-toxic and most likely a choice for your current ceiling. We start by 3D printing ceilings and aim to follow the path that leads us all to robotic creation of beautiful, curved homes - a concept we showcase in the video.
