This review article explores the use of 3D printing in the biomedical field. Although various 3D printing techniques exist, fused deposition modelling (FDM) is an exceptionally versatile choice for crafting biomedical prototypes and structures. The utilization of 3D printing offers many advantages in the biomedical field, particularly in dental implants. Notably, they can provide patient-specific designs and unique implant structures. To utilize the full potential of the FDM technique in any field, including biomedical industries, it is imperative to understand its mechanical properties. Factors such as the gap sizes between adjacent paths and filament orientations influence mechanical performance. For instance, smaller gaps can enhance the material density, whereas meticulous filament orientation optimization enhances structural integrity. This review article provides an overview of the role of 3D printing in biomedical applications, including mechanical properties and dental prototypes. A promising future for this technology is to improve patient care and outcomes.
