Some examples include an additive manufacturing system including a processor and a memory to store instructions to cause the processor to ate print data related to a three-dimensional build object. The generated print data comprises defined print data to print a first part and a second part of the object. The defined print data is to orient and position each of the first part and the second part of the object within a build area, the first part including a first mating section, the second part including a second mating section, the first and second mating sections shaped and sized to be matingly coupled to form the build object, to adjacently align the first and second mating sections within the build area, and to separate the aligned first and second mating sections with a gap defined between the first and second parts along the aligned first and second mating sections.

A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The method includes: preparing a first mixture of a first metal powder and a first binder, and a second mixture of a second metal powder and a second binder; molding the first mixture into a first body including a first connection member having a first pinhole; molding the first mixture into a second body including a second connection member having a second pinhole to communicate with the first pinhole; arranging the first body and the second body to align the first pinhole and the second pinhole along an axis to form a cavity; forming a pin member with the second mixture in the cavity by adding up droplets of the second mixture in the cavity; and sintering the first body, the second body, and the pin member.

An article comprising additively manufactured metal portions is described. The article comprises a first additively manufactured metal portion, and a second additively manufactured metal portion coupled to the first additively manufactured metal portion at a welded joint. The article further comprises a resistive heating material disposed within an interior of the welded joint, the resistive heating material comprising a different material than the first additively manufactured metal portion and the second additively manufactured metal portion.

A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The door hinge includes: a first body configured to include at least one first connection member in which a first pinhole is formed; a second body configured to include at least one second connection member in which a second pinhole communicating with the first pinhole is formed; and a pin member configured to be added and filled in a cavity formed by communicating the first pinhole of the first body and the second pinhole of the second body with each other so that the first body and the second body are foldably connected to each other.

Power transmission systems are provided that include polycrystalline diamond power transmission surfaces that are engaged with diamond solvent-catalyst power transmission surfaces. The power transmission systems may be or include gears, universal joints, or other power transmission systems or components.
