    Abstract: Methods of forming three-dimensional metallic objects are provided. A metal oxide paste comprising metal oxide particles, a polymeric binder and an organic solvent is extruded through a tip to deposit sequential layers of the metal oxide paste on a substrate to form a three-dimensional metal oxide object. The three-dimensional metal oxide object is exposed to a reducing gas at a temperature and for a period of time sufficient to reduce and to sinter the metal oxide particles to form a three-dimensional metallic object. Depending upon the composition of the metal oxide paste, the three-dimensional metallic object may be composed of a single metal, a simple or complex metal-metal alloy, or a metal-ceramic composite.

    Abstract: Disclosed is a method of manufacturing a connecting rod by using semi-closed sinter forging. The method includes: a first step of positioning a metal powder of a sintering material in a closed mold and then forming a preliminary formed body by using a general forming press; a second step of heating the formed preliminary formed body to sinter the preliminary formed body; a third step of semi-closed forging the sintered preliminary formed body to manufacture a forged part; a fourth step of cooling the manufactured forged part to normal temperature; a fifth step of removing a flash from the cooled forged part through a punching process; and a sixth step of manufacturing the connecting rod through a shot blast treatment in order to remove a foreign substance existing on a surface of the forged part from which the flash is removed.
