A COMPREHENSIVE REVIEW OF ADVANCES AND APPLICATIONS OF 3D PRINTING TECHNOLOGY

3D printing, commonly referred to as additive manufacturing, has become one of the most influential technological innovations in modern manufacturing and product development.Unlike conventional manufacturing techniques that remove material to shape an object, 3D printing constructs components layer by layer using digital design models.This approach allows the creation of highly complex structures, improved design flexibility, and efficient use of materials.In recent years, continuous progress in printing technologies, advanced materials, and digital design software has significantly broadened the scope of 3D printing across multiple sectors, including healthcare, aerospace, automotive engineering, construction, and education.This review article presents an overview of the latest developments in 3D printing technologies and examines the key printing methods currently in use.It also discusses the diverse applications of 3D printing in various industries while evaluating its benefits, existing challenges, and future potential.As the technology continues to evolve, 3D printing is expected to play an increasingly important role in shaping next-generation manufacturing systems and innovative product design.
