Recent Advancements in 3D Printing and Its Applications

Three-dimensional (3D) printing or additive manufacturing has revolutionized design and production by enabling complex geometries and personalized parts that were infeasible with traditional manufacturing methods. In the past five years, new materials (e.g. advanced polymers, composites, ceramics, hydrogels and even smart alloys) and processes (e.g. 4D-printing, bioprinting) have dramatically expanded 3D printing’s capabilities. For example, modern systems can now print metals, fiber-reinforced plastics, and biodegradable polymers.
