Abstract The ever increasing demand for new products accelerate the growth of manufacturing technologies. Additive manufacturing is the most popular among them due to its ability to print complex customized geometries. Applications were limited to rapid prototyping at earlier stages which limited its potential. But the technology advancements and researches helped in taking the technology to the next level of customized functional end use products. The applications are diversified into various fields including aerospace, medical, automobiles etc. Traditional layer by layer making of specified products are slow and lacks surface quality. In this paper, the current state, advancements and future of photopolymerization based additive manufacturing is explored. Stereolithography, the first commercial additive manufacturing technology is based on the principle of vat photopolymerization. Process speed improvement of 100 times is achieved using Continuous Liquid Interface Production. This technology lifted three dimensional objects continuously from the resin pool by proper control of oxygen and light. Dual wavelength photoinitiation and photoinhibition method printed objects at a speed of 2 m/hour approximately. The latest trend, volumetric additive manufacturing where simultaneous printing of all points within the target geometry is made possible by the rotation of resin container to dynamic light patterns using digital light projection system. The future of additive manufacturing is promising and in fact Industry 4.0′s major component.
