Abstract: A fused deposition modeling printer comprises a head assembly comprising a heating head. The heating head has a top, a bottom, and a conduit extending between the top and the bottom, wherein the surface of the conduit is adapted to guide a flow of material therein. The heating head comprises an electrically conductive layer along the conduit surface that, when powered, generates heat heating the flow of material traveling in the conduit. One realization uses top and bottom electrical contacts. One realization uses several circumferential electrical contacts to power the heating head.

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.

Abstract: A material delivery device for an additive manufacturing device (AMD) adapted for manufacturing objects through deposition of additive material over a build surface. The material delivery device comprises an inner funnel having a large aperture and a small aperture whereby the additive material is guided from the large aperture to the small aperture; wherein the inner funnel is electrically conductive and, upon applying an electrical current to the inner funnel, heat is generated thereby heating the additive material travelling in the inner funnel.

Abstract: A fused deposition modeling printer comprises a reservoir for raw material, heating head assembly and a feeding conduit connecting the reservoir to the heating head. The heating head defines a sealed enclosure and comprises a conduit comprising a conduit surface for guiding a flow of material therein; an electrically conductive layer providing an electric resistance along the conduit surface for heating the material onto molten material; an electrolysis component located in the conduit distant from the conduit surface, comprising an electrolysis electrode; a nozzle through which exits the molten material from the heating head; an exhaust outlet for discharging gas resulting from the electrolysis out of the heating head; and a feeding conduit connecting the reservoir to the heating head. The fused deposition modeling printer is adapted to perform at the same time material deposition and electrolysis of the molten material.

Abstract: System and method for reducing processing delays when interfacing with a computing device. The method comprising predicting a user event using sensors or information stored in memory, and pre processing the command associated with the predicted user event before receiving a user input confirming the predicted user event. The preprocessing data is output to the user after receiving a user input confirming the predicted user event. Thereby, reducing processing delays associated with the user-event.
