Outline of Final Research Achievements |
This study aims at constructing a new fabrication method for additive manufacturing with bio-degradable conductive materials. In the present method, ultrasonic vibrations are applied to the material extrusion process for utilizing thixotropic property of the material, in which the viscosity of material becomes lower on vibration-applied conditions and recovers on still conditions without vibrations. After the property of subject materials was confirmed by viscosity measurement experiments with vibration, material extrusion experiments with metal filler suspensions were conducted by using a developed device, which can extrude a small amount of materials with ultrasonic vibrations generated by an ultrasonic homogenizer. The experimental results showed that the ultrasonic vibration enabled the material to be extruded with a lower pressure than conventional conditions. Finally, 3-dimensional shapes could be fabricated by the present method.
