Title: 3D PRINTING METHOD OF FORMING A BULK SOLID STRUCTURE ELEMENT BY COLD SPRAY
Abstract:
A method of forming a three dimensional object using a low pressure cold spray process for is disclosed. Powdered material is delivered at a temperature below the melting point of the powdered material. A nozzle of a cold spray gun is aligned at an angle θ1 to the substrate. The powdered material is delivered at a supersonic speed to the substrate causing the powdered material to adhere to the substrate for forming a first layer of material. An amount of optical distortion caused by the first layer of material adhered to the substrate is determined relative to the substrate and the nozzle is reoriented to an angle θ2 being offset from an axis defined by the first layer of material. A second layer of material is deposited onto the first layer of material with the nozzle being oriented at the angle θ2 to the first layer of material.
