Evaluation of Antibacterial and Mechanical Properties of 3D Shaped Metal-containing PLA resin

抄録

There is a fused deposition modeling method as a three-dimensional modeling method that mainly uses a resin filament. By this method, modeling using a resin filament containing a metal is also possible. When the metal-containing PLA filament was three-dimensionally modelled under the same conditions as the pure PLA filament, defects were likely to occur in the modelled object regardless of the printing speed, melting temperature, and bed temperature, resulting in inferior strength. In addition, when a JIS standard antibacterial property test was conducted on a PLA filament model containing copper even at a few percent, antibacterial properties were confirmed against multiple bacteria.
