Much of the progress in RP processes such as laser stereolithography, selective laser s intering, fused deposition modeling and 3 D printing has occurred owing to the development of new materials. Likewise, the progress from mere ‘look alike’ to functional parts has required the development of appropriate materials. This chapter provides a basic introduction to classes of materials that are of particular importance in gaining a deeper understanding of the concepts covered in subsequent chapters. In particular, ceramic, polymeric, powdered, and composite materials are covered in view of their wide use in RP. Although of equal importance, a discussion of metals is not included in the expectation that engineering students and professionals would already be quite familiar with them.
