Abstract
Rapid prototyping (RP) or additive manufacturing (AM) is a group of technologies that create three dimensional objects additively in a layer-by-layer manner. This chapter first discusses the definition of RP. It goes on to describe the basic process, the classification of RP and typical RP systems. Finally, the chapter discusses how RP can be explored for processing biomaterials and suggests possible research directions. It is the intention of the authors that this chapter will give readers a general view on rapid prototyping of biomaterials.
