| Description |
Research was conducted for the development of formulations for additive manufacturing of metal nanoparticles that produced a 3D printed metal object without oxidation but with material properties and corrosion resistance similar to existing approaches. The study was designed around experimentation of different liquids/viscous fluids that when mixed with metal nanoparticles formulated a paste that can be used in extrusion 3D printers. A suitable binding agent, water/ethanol-based gel, was chosen to produce the initial paste to be 3D printed. The ideal printing conditions for the metal powder paste were found through trial and error. The pastes and products were analyzed and tested for oxidation and material properties using X-ray diffraction, electron microscopy, and nano mechanical testing. The study was limited to the use of copper alloys, for example, monel. The finished product was a metal design that retains the material properties of the desired metal and a Vickers hardness of 99.78. The porosity was able to be reduced to 10.56% in the sample after heat treatment. Subjects: extrusion printing; metal nano particles; electron microscopy; paste formulation; 3D printing; Cu alloys |
