Additive manufacturing (AM) has revolutionised numerous sectors of the economy by providing highly accurate, customisable, and economical production techniques. AM takes a lead role in delivering patient-specific therapy, especially in implant and scaffold fabrication for tissue engineering. AM has several benefits compared to conventional manufacturing techniques, such as the capacity to produce intricate geometries, shortened patient wait times, and increased surgical precision. This chapter briefly discusses AM and its process of creating implants and scaffolds. This chapter identifies major AM areas for implant and scaffold printing and discusses them further. Customised prostheses can also be manufactured by using this technology. 3D printing is an essential component of AM, which uses layers of material to manufacture an item based on a digital model provided to it. Depending on the final object’s required qualities, the printer can use various materials, including metals, ceramics, and polymers. A prosthetic hand deploying 3D printing can resemble a patient’s natural hand. Prosthetic sockets that are more secure and pleasant than conventional sockets may also be made with the application of AM. Using a patient-specific design may cut down waste and increase productivity. Unlike conventionally manufactured, patient-specific implants, 3D printing offers superior anatomic fit, shorter operating times, and pleasing cosmetic outcomes. With customised implants, doctors can reduce the recovery time, restore the defect as best they can, and reduce the trauma, leading to better patient outcomes.
