Abstract: A method for operating a printer can include placing a first print material into a supply reservoir of the printer. The method also includes placing a second print material into the supply reservoir to combine with the first print material to form a diluted print material. The method also includes causing the diluted print material to exit the supply reservoir. Another method for operating a printer includes adding a first print material having a first melting point to a supply reservoir at a first rate. The method also includes adding a second print material having a second melting point to a supply reservoir at a second rate. The method for operating a printer also includes allowing the first print material and the second print material to combine to form a diluted print material. A printing system is also disclosed.

Abstract: A method for printing a 3D part includes decreasing a temperature of a build material in a nozzle of a 3D printer below a melting point of the build material, which causes the build material in the nozzle to transition from a liquid state to a solid state. The method also includes increasing the temperature of the build material in the nozzle above the melting point of the build material, which causes the build material in the nozzle to transition from the solid state to a sludgy state. An occlusion and the build material in the sludgy state are ejected from the nozzle.

Abstract: A metal component is disclosed. The metal component has a first dimension greater than 5 mm, and a second dimension greater than 5 mm. The metal component may include where the alloy includes titanium, aluminum, vanadium, carbon, nitrogen, and oxygen. The alloy may include zirconium, titanium, copper, nickel, and beryllium. The metal component is not die-cast, melt-spun, or forged. An ejector and a method for jetting the metal component is also disclosed.
