  • Publication number: 20240207925
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a movable directed energy source to melt hardened metal drops and form an oxidation layer. A metal support structure can be formed over the oxidation layer, an object feature can be formed over the oxidation layer, or both a metal support structure and an object feature can be formed over oxidation layers located at opposite sides of a metal support structure. The oxidation layers weakly attach the metal support structure to the object feature supported by the metal support structure so the support structure can be easily removed after manufacture of the object is complete.

  • Patent number: 11992879
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a borate solution application system to apply a borate solution to a build platform surface prior to manufacture of a metal object. The borate solution is permitted to air dry before the platform is heated to its operational temperature range for formation of a metal object on the platform. The evaporation of the solvent from the borate solution causes the borate salt to form a glassy, brittle anhydrous borate layer on which the metal object is formed. This brittle layer is removed relatively easily with the object after the object is manufactured and the build platform is permitted to cool. The borate layer improves the wetting of the surfaces of build platforms made with non-wetting materials, such as oxidized steel, while also preventing metal-to-metal welds with wetting materials, such as tungsten or nickel.

  • Patent number: 11878349
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with two solid metal moving mechanisms that are independently operated to move two different metals into the receptacle of a vessel in a melted metal drop ejecting apparatus. The ejector is operated to form object features with melted metal drops of one of the two different metals and to form support features with melted metal drops of the other of the two different metals. The thermal expansion coefficients of the two metals are sufficiently different that the support features easily separate from the object features after the object and support features cool.

  • Patent number: 11858276
    Abstract: An implementation of the present teachings includes a resistor structure for measuring a level of a print material such as a liquid metal print material within a reservoir of a printer such as a magnetohydrodynamic printer. The resistor structure includes a first electrode and a second electrode that are physically and electrically separated from each other. When positioned within the reservoir, the liquid metal physically contacts the first electrode and the second electrode. An electrical resistance between the first and second electrodes changes depending on the level of the print material within the reservoir. As the level of the print material decreases, the electrical resistance between the first electrode and the second electrode increases. The electrical resistance can be measured and used to determine a level of the print material within the reservoir.

  • Patent number: 11850861
    Abstract: A method analyzes image data of a test pattern printed on an image receiving member by a printer to identify split inkjets in the printheads of the printer. The test pattern is formed by operating each inkjet of a printhead to form a dash and the areas of the dashes are compared to an average dash area to identify split inkjets. Firing signal parameters for the split inkjets are adjusted and subsequent firing signals are generated using the adjusted parameters. Image data of the pixels formed by the split inkjets are analyzed after the split inkjets have been operated using the adjusted firing signal parameters. If the pixel size for a split inkjets indicates that the split inkjet has been remediated, then the firing signal parameters are returned to their nominal values.
