Abstract: Described is a self-cleaning extrusion orifice assembly including an enclosure, a cylindrical body inserted into the enclosure and terminated by an extrusion orifice. The self-cleaning extrusion orifice assembly is operated by a pressurized air flow. The pressurized air flow flushes surfaces of some elements of self-cleaning extrusion orifice assembly removing debris that could be deposited on these surfaces. In addition, some elements of self-cleaning extrusion orifice assembly are configured to scrape extrusion process debris from the same surfaces.

Abstract: A method and apparatus for manufacturing of 3D objects. The apparatus includes a number of material deposition heads terminated by nozzles, of which one or two nozzles are configured to deposit a first material to form a first and second pattern layers. The pattern layers are laterally shifted from each other such that when the first and second pattern layers are deposited, a space (empty volume) with a varying cross section is formed. In some examples, two or more nozzles could be used to deposit the corresponding first and second pattern layers. The nozzles could move independent of each other.

Abstract: An apparatus and method for generating support structures to 3D objects. The support structure could be located in an inner space or cavity of a hollow 3D object. In some examples, where the inner structure cannot support the designated segment of the 3D object, the support structure could be implemented outwards.

Abstract: The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic flame retardant material in gel aggregate state. The gel flows through a deposition nozzle because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength.

Abstract: A printing system for printing the lower base of a wind tower or the entire wind tower. The system includes a printing device configured to print the coaxial polymeric shells with an empty volume between the shells. The printing device uses the coaxial polymeric shells as driving rails. A concrete material deposition device configured to deposit the concrete material into the empty volume between the polymeric shells, and a rebar handling device is configured to deliver rebars into the volume between the polymeric shells to reinforce the deposited concrete material.
