Polymer 3D printing is an emerging technology that further research in this field will lead to continuous improvement of polymer 3D printing design performance, which is necessary to push the boundaries in engineering and medicine. Polymer 3D printing provides the possibility of printing low-cost functional parts with various properties and capabilities. Here, by reviewing research on materials, processes and related strategies applied for medical applications, it is presented. Research in materials has led to the development of polymers with useful properties for mechanics and biocompatibility, by tuning the mechanical properties achieved by changing the parameters of the printing process. Polymer 3D printing technologies include extrusion, sheet lamination, Vat photo polymerization, additive layer, powder-based fusion, material projection, direct energy deposition. Thermal and laser inkjet techniques are more common. The two technologies of sheet exfoliation and direct energy deposition have limited medical applications. Which enables the direct deposition of design materials for useful and customized architectures. Design strategies, such as the hierarchical distribution of materials, make it possible to balance contrasting properties. The most investigated medical applications include tissue scaffolds, dental implants, medical education, delivery systems, and drug safety devices. And finally, the challenges and obstacles of polymer 3D printing were studied.
