The term "3D printing" encompasses several distinct additive manufacturing technologies, each utilizing different materials and methods to achieve the final product. In the healthcare apparatus sector, the most prevalent technologies are Stereolithography (SLA), Selective Laser Sintering (SLS), and Direct Metal Laser Sintering (DMLS).

SLA, which uses a laser to cure liquid photopolymer resin, is known for its high resolution and smooth surface finish, making it ideal for detailed anatomical models and certain surgical guides. SLS, which uses a laser to fuse powdered polymers, is favored for strong, durable parts like prosthetic components. For metal implants that require extreme strength and biocompatibility, DMLS is used, fusing metal powders like titanium or cobalt chrome layer by layer.

The selection of the appropriate technology is critical and depends entirely on the application: resolution and smooth finish for visualization, durability for prosthetics, or metallic strength for implants. This reliance on diverse, specialized printing methods highlights the technical complexity driving the additive manufacturing domain.
