![]() ![]() Suitable for a narrow range of materials. Material wastage occurs in various forms like chips, vaporization, etc. No or very less material wastage takes place. Volumetric density of the working material cannot be altered during operation. Volumetric density of the working material can be altered during operation Melting point usually does not pose any restriction on it. Suitable for materials having low melting point. Layers of material are removed from a solid block to obtain desired 3-D component. Layers of material are added one over another to build 3-D component. ![]() Subtractive Manufacturing:In an subtractive manufacturing process layer by layer material is removed from the solid workpiece to finally produce intended product.ĭifference between Additive and Substractive Manufacturing.Additive Manufacturing:In an additive manufacturing process layers of material in semi-solid form are added one over another to directly build a true three dimensional component having required features and enhanced accuracy.
