Three dimensional (3D) printing in Orthopaedics: Scope of application and future perspectives

Abstract

Three dimensional (3D) printing also known as additive manufacturing has the potential to change the paradigm of Orthopaedic practice. Modern times have witnessed exponential growth in 3D-printing technology as well as its uses. A wide spectrum of printers are now available, ranging from the desktop printer to high end manufacturing units. The ability to use a plethora of materials and create almost limitless geometric shapes with varying surface topography makes this method of production highly appealing. Certain inherent advantages include easy customizability, small production runs, less wastage of material, smaller footprint. Challenges such as lack of data, absence of established government regulations and cost considerations remain, but one can expect these to be overcome as the economy of scale plays out and the medical fraternity becomes more accommodating of the new technology.
