Difference Between Additive and Subtractive Manufacturing

In additive manufacturing, layer by layer material is added one over another to develop desired solid 3-D product. In subtractive manufacturing, layer by layer material is gradually removed from a solid block to fabricate 3-D product. This manufacturing concept is usually suitable for materials having low melting point, such …

Additive or Subtractive Manufacturing: Which is Better?

Subtractive manufacturing is able to produce complex shapes as well but does not offer nearly the same level of design freedom as additive manufacturing. Waste Subtractive manufacturing relies on the removal of bulk material to achieve a desired object, however, this can yield a substantial amount of waste as unusable chips, dust, scraps still remain …

A manufacturing layer (i.e., a cutter contact (CC) curve in machining or a build layer in printing) must be processed in one single subtractive or additive sub-sequence. If a contour (to machine or to print) is divided into two separate sub-sequences, it would be counterproductive and defeat the purpose of achieving high finish-surface quality.
