Abstract:
In the machine parts as sliding members, complex shapes and small-lot production are required. Therefore, manufacturing with Fused Deposition Modeling (FDM) technology using resin materials has attracted attention. However, in this method mechanical properties are inferior to those of metallic materials. In addition, many of the resin materials are petroleum-based resins, and environmental problems are a concern. In this study, it was tried to improve it by mixing polylactic acid (PLA) with MoS2 as solid lubricants. PLA is a material with carbon-neutral properties. In the experiment, we used specimens made by a 3D printer after mixing raw materials and passing through intermediate materials. The stability of the composite is worse than that of PLA alone in friction tests. However, the coefficient of friction was partially low. This is thought to be the result of the function of the properties of MoS2 as a solid lubricant.
