Three-dimensional (3D) photopolymerization in the stereolithography. Part II. Technologies of the 3D photopolymerization

A review with 28 references covering 3D computer-aided de sign (CAD)-computer-aided manufacturing (CAM) devices and techniques used in 3D photopolymerization and micromachining processes applied to make stereolithographic products.The former comprise mechanically scanned devices with a stationary laser spot and optically scanned devices with a moving laser spot, laser types (HeCd; argon-ion) including excimer lasers (Nd:YAG, Nd:YLF) associated with 3D photopolymerization tech niques and stereolithography software.Micromachines are reviewed and micromachining processes are described used to make stereolithographic products.
