3D Printing with Composite Materials


3D Printing with Composite Materials



Technology Summary


  • 3D printing eletronics is the manufacturing of electronic devices by 3D circuit's modeling and 3D printing processes.
  • 3D printed electronic devices are equivalent to the plastic itself with the circuitry (i.e., wiring and limped RLC circuits) not only on exterior surface but also within interior structures
  • Development of composite metals with a high conductivity, low Tmelt (< 400 ℃), various viscosity (10~10,000 cp), and various carrot (< 22 K)
  • Capability in 3D printing the composite metals (Cu, Au, etc) and polymers simultaneously by a material jetting(MJ) or FDM
