Additive manufacturing by digital light processing: a review

Abstract Additive manufacturing is a layer-by-layer strategy enabling the advanced design and fabrication of complex 3D objects structures, overcoming geometry limitations reducing waste production compared to conventional technologies. Among various additive technologies, digital light processing (DLP), an technology used print photopolymer parts, using projected source cure entire layer at once. Initially developed for pure resins, recent advances have demonstrated potential DLP in polymerization ceramic metal-loaded suspensions, metal components after proper debinding sintering. Such flexibility increases different applications, ranging from dental implants bone scaffolds smart biomaterials soft robotics, wearables, microfluidic devices. The review provides overview its advances; specifically, covers properties, metallic feedstock preparation, light-matter interaction mechanism underpinning printing post-processing steps. Finally, description current application provided complemented with future perspectives.
