3D printing is a versatile technology having its applications ranging from diagnosis and clinical evaluation, preoperative planning, patient, and resident education along with device development and innovation. In this blog, we will explore the different applications of 3D printing like Medical models, Patient specific implants, Prosthetics/orthotics and Surgical guides and their extensive use in different healthcare specialities. While 3D printing technology has applications across a wide range of medical specialties, we will focus our discussion around orthopaedics, neurosurgery, maxillofacial surgery, dentistry, plastic surgery, and beyond, unveiling how this cutting-edge technology is revolutionizing patient care and medical interventions.

Applications of 3D printing in healthcare

1. Orthopedics

3D printing has provided orthopedic surgeons with a new technology that has the potential to revolutionize preoperative planning, surgical instrument development, and custom orthopedic implant creation for precision medicine and personalized treatments. The availability of highly affordable and advanced prosthetics such as artificial hands with mechanical components, limb replacement and hip joint prosthesis etc. have shown successful outcomes and the complex anatomical models for better understanding pathology and fracture patterns.

2. Neurosurgery

3D printing enables the neurosurgeons to visualize intricate, minute anatomical structures noninvasively for both diagnosis and surgical treatment. The incorporation of patient-specific anatomical models and surgical guides in neurosurgery for surgical planning, surgical guides, devices for the assessment and treatment of neurosurgical disease and the development of biological tissue-engineered implants.

3. Maxillofacial surgery

Maxillofacial surgeons utilize 3D-printed models to plan complex reconstructive surgery , ensuring optimal outcomes and patient satisfaction. Maxillofacial region reconstructions which require a lot of planning, precision, and multiple surgeries. Implementation of 3D Planning tools indicate uniform long term functional and aesthetic outcome, thereby improving facial symmetry and function.
