A 3D printing mechanism comprising a planar build surface 15 that rotates in relation to a multiplicity of print heads where each head as a multiplicity of nozzles 2. The nozzles are preferably moveable to allow layers of material to be built up; and may extrude thermally or chemically solidifiable material and clay in the form of spiral tubes or beads that lay on top of each other and interlock to form a spherical structure that floats and can be used a residential building; the nozzles can also apply a waterproof membrane or glaze. The extruded bead may have a cavity to provide buoyancy to the building. The nozzles may be attached to a framework that has robotic arms attached that place components such as electrical circuits, doors and window frames onto the planar surface or into the 3D object that is being printed. The nozzles may be feed by augers and have means to heat the material to be extruded if required; one of the augers may be supplied by raw material that is drilled from the manufacturing site, which is preferable located alongside or on a watercourse. Alternatively the framework may be rotated around the planar building surface. |
