Comparison of Additive Manufacturing and Subtractive Manufacturing

COMPARISON OF ADDITIVE MANFACTURING AND SUBTRACTIVE
MANUFACTURING

Abstract:
CNC based subtractive manufacturing has been in industry standard by which many of the parts
and products have traditionally been realized. With respect to advanced manufacturing these
processes typically require an appreciation for part digitization, CAD/CAM and the intrinsic
machine-ability, while materials are eroded to product the end product. This could be greatly
achieved by Additive manufacturing. Our main objective is to deal with the effective usage of
additive (3D Printing) and subtractive (CNC machining) manufacturing process machines over
various fields. The comparison of these manufacturing processes has also been made and
described in our paper.
