Optical 3D Printing Optical 3D printing uses light-based technologies, such as stereolithography (SLA) and digital light processing (DLP), to cure photopolymer resins layer by layer. It provides high resolution, smooth surfaces, and intricate details. Optical 3D printing is widely used in jewelry, dental models, and microfluidics. It utilizes UV or laser light to solidify resin with precise control over layer thickness. Advanced optical systems enable multi-material and color printing. Proper calibration of exposure time, layer height, and support structures ensures high-quality prints with accurate dimensions. |
