Additive manufacturing (AM), commonly known as 3D printing, builds objects layer by layer from digital models. It enables complex shapes, custom parts, and local production. 3D printing has grown rapidly and is used across industries including aerospace, healthcare, automotive, construction, and consumer goods. This paper reviews the main 3D printing processes, their operating principles, and materials. It also examines key applications, practical demonstrations, and challenges. Representative experiments and case studies (e.g. mass production of engine parts, printed medical devices, COVID-19 face shields) illustrate current practice. The review highlights how 3D printing has reduced assembly time and waste, and how innovations (like bioprinting and new materials) are expanding possibilities. The paper concludes by exploring emerging trends and future directions in 3D printing technologies and their applications.
