In the field of orthopedics, the use of additive manufacturing (AM) has skyrocketed. Anatomic models, surgical instruments and tool design, splints, implants, and prosthetics are all examples of AM applications. A review of several research papers reveals that patientspecific orthopedic procedures have a wide range of applications and can help guide future development. This work aims to figure out how to make the most of additive manufacturing applications in the orthopedic field. It also explains how to prepare a 3D printed model using this technology and gives examples of orthopedic applications. In the field of orthopedics, AM provides a versatile solution in which customized implants can be molded to the appropriate shape and size, allowing for replacement with customized items. This technology creates a 3D model of the patient's anatomy that can be used to conduct mock procedures and is useful for extremely complex surgical pathologies. A plaster cast is mainly used for the treatment of fractures but it has some side effects such as itching, burning sensations, etc., so an alternative made of PLA material(which is devoid of the mentioned side effects) is developed. This model is developed for curing TFCC(Triangular Fibro Cartilage Complex) tear which is a type of fracture that may take as long as 12 weeks to heal. The model is designed in such a way that it should fit any person no matter what the size of their hand is. It simplifies the surgeon's job and improves the operation's success rate. By allowing for infinite geometric flexibility, AM allows for a better fit implant for each patient Various scanning methods are used to capture the status of bone defects, and this technology is often used to print the model. It produces a precise physical model that can be used in medical education, surgical preparation, and training. Since each patient's data is unique, this technology will aid in the resolution of current issues.
