Chapter Outline
As AM technology has matured over the last 30 years, a wide range of materials including those with engineering properties are now available. While there are fewer choices than for conventional manufacturing processes, almost all classes of polymers, metals, and ceramics are available such that a product team does not have to rule out the use of AM due to a lack of suitable materials. However, achieving suitable properties is still not guaranteed. In this chapter, we will discuss the primary engineering materials classes: polymers, metals, composites, and ceramics, as well as other materials.
