It was first used in the late 1980s and was developed to apply the precision and functionality of computer assisted design (CAD) to manufacturing ( 5). Rapid prototyping (RP) is an additive manufacturing technique that works by building a model from the ground up, depositing material layer by layer.

Currently, per our review of the literature, nearly every surgical specialty has published applications for 3D printing. It has been suggested this is largely because 3D printing is more suitable to fields that handle hard tissue since the first 3D printers could only print with hard materials ( 4). Orthopedic surgery and Oral and Maxillofacial surgery were among the first specialties to adopt this technology. SLA was the first 3D printing technique available and the first used in the biomedical field, in 1994 ( 3). Stereolithography (SLA) is the technique by which a computer controlled laser been is used to harden a liquid polymer or resin, creating a structure layer by layer. With the introduction of the first commercial 3D printing machine in addition to increasing access to 3D medical imaging techniques in the late 1980s, applications for 3D printing in the medical field began to be seriously considered. It was a model pelvis that was milled from a polystyrene block ( 2).

The first anatomic model constructed with the use of medical imaging was done that same year. However, sometimes there is additional work done on the part by hand to further refine it. This technique usually starts with a blank block of material that is slowly shaped into the final part. The computer controls the tools needed for fabrication of the part by controlling the lathes, mills routers, and grinders used in the process. Prior to the advent of 3D printers the main method of fabricating a unique part for prototyping was with the use of Computer Numerical Controlled (CNC) machine. At that time, there were no rapid prototyping (RP)/3D printing systems available, however subtractive manufacturing, or milling, was a possibility. Historically, the concept of using 3D medical imaging, specifically computed tomography (CT) data, to reconstruct a physical model was first suggested in 1979 ( 1). The recent explosion in popularity of 3D printing is a testament to the promise of this technology and its profound utility in surgery. Furthermore, surgeons have gone beyond printing these impressive patient-specific anatomic models to printing patient-specific medical hardware, such as implants, prosthetics, external fixators, splints, surgical instrumentation, and surgical cutting guides. Nearly every part of human anatomy that can be operated on has had a 3D model printed of it. Three dimensional printing technology has been adopted by surgeons at an impressive rate and in a large variety of applications. Keywords: Three-dimensional printing surgical specialties surgery computer-aided design review Incorporating 3D printing into a surgical practice can be a rewarding process that yields impressive results. Decreasing cost and increasing ease of use are making this technology more available. There is large array of potential applications for 3D printing. Also, the diverse and increasing applications of 3D printing were recorded and are discussed. The pertinent considerations for getting started with 3D printing were identified and are discussed, including, software, printing techniques, printing materials, sterilization of printing materials, and cost and time requirements. We found an exponential increase in studies addressing surgical applications for 3D printing since 2011, with the largest growth in craniofacial, oromaxillofacial, and cardiothoracic specialties. Data was manually extracted from the 168 included studies. PubMed was searched for studies that addressed the clinical application of 3D printing in all surgical fields, yielding 442 results.

It is important to learn how 3D printing has been used in surgery and how to potentially apply this technology. The profound utility of this technology in surgery explains the exponential growth. It has been used to print patient-specific anatomic models, implants, prosthetics, external fixators, splints, surgical instrumentation, and surgical cutting guides. This technology has been adapted to a wide range of surgical applications at an impressive rate. Abstract: Three dimensional (3D) printing involves a number of additive manufacturing techniques that are used to build structures from the ground up.
