One of the lesser known 3d printing technologies is sheet lamination, sometimes also known as laminated object manufacturing (LOM).

 .

It is considered additive because one sheet of material is bound to another, in a layer by layer process. Early sheet lamination systems used ordinary paper that may have been coated with a binding agent or that had a binding agent sprayed on during the process. More modern methods converted to using a coated paper, which simplified the equipment. In some cases, colored paper was used, in other cases colored inks were deposited onto the paper to achieve a color three-dimensional object. In most cases, the final part was either cut layer by layer with a laser or a blade. This technology was primarily used for prototyping or “look and feel” proofs of a design. Because of the binding agents, objects made through sheet lamination often had wood-like properties. They […]
