A major issue in the medical field worldwide is the limited number of organ donors available for transplants. The conventional methods are constrained by issues like scarcity of donors, further harm, and limited resources. The 3D printing technology provides a hopeful remedy by allowing the quick creation of customized tissue scaffolds, fixing tissue defects with cells, and potentially printing organs and tissues. These customized implants blend with the patient's tissue and include specific material patterns and cell clusters to promote cell growth and maturation, aiding in tissue repair. This review examines the existing obstacles and progress in 3D printing for medical purposes, specifically focusing on materials and extracellular matrix fabrication, showcasing different types of biomedical materials and recent innovations.

The realm of 3D printing is rapidly evolving, offering a wide range of options from typical thermoplastics to advanced graphene-based composites. This technology improves production efficiency and gives consumers more control over customizing products and specifications. However, alongside its transformative potential, 3D printing also presents challenges, such as potential impacts on manufacturing jobs and security issues. Since its modest beginnings in developing visualization models, 3D printing has evolved to transform the manufacturing of distinct devices, implants, tissue engineering scaffolds, and drug delivery systems. This paper explores the most recent progress in 3D printing materials, including smart materials, ceramics, electronics, biomaterials, and composites, emphasizing the significance of adapting to changing materials and product requirements. It delves into the complex connection between printing parameters and the characteristics of printed composite parts, providing new opportunities to improve the strength and functionality of 3D-printed components. This review highlights how 3D printing can be utilized in various industries, such as medical devices and explosives research, using materials such as titanium, aluminum, carbon fiber, and thermoplastic polyurethanes. With the continuous growth of the 3D printing field, it is essential to adopt new methods and materials to fully realize its impact on the future of manufacturing and product development.
