Each rapid prototyping method has a unique set of materials with which it works. Laminated object manufacturing (LOM) is no different. This procedure requires two things of its materials. The first is the ability to be layered. Because LOM makes each layer separately and attaches them after they are cut, the material being used must be able to be divided into layers before the process begins. The second requirement of LOM's materials is the ability to be attached by layer. After the layers are cut, they are attached to already constructed layers by means of a thermal roller. For this reason, each material must be able to interact with some type of thermal adhesive (most likely a thermoplastic or glue) in such a way that the combined layers result in the feel and appearance of a completely solid object.

Because of these requirements, laminated paper is one of the most popular materials for LOM. When completed, this material is very comparable to a block of wood. Sheet plastic, and ceramic and metal tapes are also used in LOM. These materials result in solid blocks of whatever compounds make them up.
