The process is similar to how a traditional printer applies ink to paper; however, a 3D printer solidifies or binds a liquid or powder material at specific points to create solid structures. The layering process is repeated numerous times until the desired object is fully formed in its vertical dimension. Objects can be 3D-printed using materials such as plastic, metal, or even biological substances, depending on the desired application. The starting material is often a fine powder, which is dispensed in small amounts ...(100 of 262 words)
