3D printing is one of the most versatile manufacturing techniques available and can be used in almost any industry. It is best put to use in cases where a part or product is highly complex in shape, for example lattice structures, or where internal detailing is required. It is also particularly suited to rapid manufacturing, and often a 3D printer can produce a finished product without the need for further assembly. It is also useful for extremely short runs, for example only one or two prototypes, as there are no tooling costs and no need to produce a mold.
