Light–Matter Complex Interactions in Stereolithographies

Since its inception in 1984, 3D printing has revolutionized manufacturing by leveraging the additivity principle and simple material–energy coupling. Stereolithography, as pioneering technology, introduced concept of photopolymerization with a single photon. This groundbreaking approach not only established essential criteria for additive processes employing diverse localized energies materials, including solid, pasty, powdery, organic, mineral substances, but also underscored significance light–matter interactions spatial temporal domains, impacting various critical aspects stereolithography’s performance. review article primarily focuses on exploring intricate relationship between light matter stereolithography, aiming to elucidate operational control strategies fabrication processes, encompassing voxel size manipulation. Furthermore, advancements excitation modes, transitioning from one-photon two-photon mechanisms, have unlocked new material creative possibilities. Notable advantages include elimination layering (true printing) ability fabricate objects using silica glass. Although these volumetric methods deviate conventional concepts possess narrower application scopes, they offer reduced design timeframes along enhanced resolution select cases. These complex form cornerstone this comprehensive review, shedding considerations stereolithography. By comprehensively analyzing impact interactions, novel excitation, highlights transformative potential stereolithography rapid precise fabrication. While techniques may occupy smaller niche within broader spectrum technologies, serve valuable additions array devices available market.
