High temperature, high pressure, powder-based, 3D printed object manufacturing

Abstract

An additive manufacturing device (AMD) for manufacturing objects through deposition of superposed layers of material in a granulate or powder form, the AMD comprising: a hydraulic cylinder; a mold for sealable attachment to the hydraulic cylinder; a material deposition station having an outlet for depositing the material in the mold layer-by-layer; a heating element; and a compressor. Between the deposition of one or more layers of material in the mold, the mold and the hydraulic cylinder are sealably attached to form a pressure container, the compressor injects gas in the container to increase a pressure within the pressure container and the heating element provides heat within the pressure container to further increase the pressure and to perform sintering or high-temperature synthesis of the material while submitting the material to the pressure.
