金属3Dプリント型ボールジョイントの摩擦特性調査

抄録

In order to demonstrate the effectiveness of 3D structured surface texturing which is named "Material feed path" for sliding applications, a 3D textured ball joint was fabricated by SLS (Selective Laser Sintering) 3D printer. Material feed paths are fine channels applied to parts supplying some material with a sliding surface. The frictional properties of the ball joint were measured by a pendulum type friction tester. The results implied that supplying a lubricant with a sliding surface via the channels enables to keep friction low for a long term.
