3D printing has opened new capabilities in creating prosthetics and orthopedics. Fused Deposition Modeling, FDM, is the most common printing method due to its efficiency and lower costs, while Thermal Inkjet Printing and Selective Laser Sintering (SLS) are two other methods seen in prosthetic fabrication. X-rays, MRI, and CT scans can be translated into digital .STL 3D print files, offering customized designs and fits. Acrylonitrile butadiene styrene (ABS) and poly(lactic acid) (PLA) are the most common materials used in prosthetics. Prosthetics made from flexible materials use NinjaFlex, a thermoplastic polyurethane, or Filaflex, a thermoplastic elastomer. SLS printers use a nylon-based material, and PolyJet printers use a photopolymer resin. However, with photopolymers, there is an issue with the material degrading in sunlight. Flexible materials have provided more options with body parts and capabilities. With the progression of prosthetics, prosthetic ears are developed with the ability to detect electromagnetic frequencies. These prosthetics are fabricated from silicon, chondrocytes, and silver nanoparticles. Most hearing aids are also 3D printed as it offers customization based on the patient's size, location, etc. Orthopedic implants are projected to expand. 3D printed implants are especially prevalent in orthopedic oncology. For example, malignant bone tumors can affect any part of the skeleton, and bone tumors have bimodal incidence, affecting young patients especially. Limb salvage surgery is a common surgery for malignant bone tumors and is individualized. 3D printed metal implants are used to reconstruct massive bone defects after a wide excision is made. However, if the bone tumor is near the joint or physis, segmental reconstruction has to be implemented. Modular implants are not utilized when reconstructing unusual sites, like the pelvis. Titanium alloy powder is used for bone reconstruction, and common printer types include electron beam melting and selective laser melting. Implants can not only focus on filling bone defects but attempt functional reconstruction. Additional 3D printed implants on the skeleton include 3D printed polyetherketoneketone (PEKK) skull implants where no shaving is necessary as the implant is a customized design and fit. There are also maxillofacial, spinal, and dental implants. Dentistry often uses titanium or ceramics for dental implants. Bioceramics offers an opportunity to produce cell-seeded implants that are patient-specific. 3D printing shows promise as it is personalized to the anatomy, color, shape, and size of the patient without the need to adjust the production machine.
