METHOD FOR PREPARING METAL INK AND ADDITIVE MANUFACTURING BASED ON PHOTO-THERMAL SYNERGISTIC CURING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240228802 titled 'METHOD FOR PREPARING METAL INK AND ADDITIVE MANUFACTURING BASED ON PHOTO-THERMAL SYNERGISTIC CURING

The method described in the patent application involves preparing metal ink for additive manufacturing using photo-thermal synergistic curing, specifically focusing on functional ink technology. The ink composition includes metal powder, photosensitive resin, photosensitive monomer, photoinitiator, thermal initiator, up-conversion material, and auxiliary agent.

  • Metal ink is added to the ink tank of a direct ink writing 3D printer.
  • The ink is extruded from the nozzle under computer control to print specific shapes on the platform.
  • Real-time illumination of a specific light source cures the ink to obtain the green body.
  • High-temperature debinding treatment is performed on the green body in a specific atmosphere.
  • The treated green body undergoes high-temperature and high-pressure sintering treatment in a specific atmosphere before cooling to room temperature.

Potential Applications: - Additive manufacturing of metal parts with complex geometries. - Production of customized metal components for various industries such as aerospace and automotive.
