Comparison of Hole Quality of Polyamide Materials Produced by Traditional and Additive Manufacturing

Abstract

Polyamide, commonly used in engineering plastics, has wear resistance and high strength. In this study, polyamide, which is produced with casting and three-dimensional printer, has been drilled and reamed in numerical controlled machine. Thus, the effect of production tech-nique, machining allowance and tool feed rate on hole surface and dimensional accuracy was investigated. In general, the surface quality of the holes in the polyamide material produced by the two production techniques was directly affected by the machining allowance and the increased feed rate. In addition, the size of the holes created with the three-dimensional printer has reached the desired level after ream-ing process.
