DLP (Digital Light Processing) printing uses photopolymer resin as the primary material. This resin is a liquid that solidifies when exposed to a specific wavelength of light, typically UV light. Here’s a more detailed breakdown of what is used for DLP printing: 1. **Photopolymer Resin**: - **Composition**: The resin used in DLP printing is composed of photoinitiators, oligomers, and monomers. When exposed to UV light, the photoinitiators trigger a chemical reaction that causes the resin to harden and form solid layers. - **Varieties**: There are various types of resins available, each designed for different applications. These include standard resins for general use, tough resins for durable parts, flexible resins, high-temperature resins, and specialty resins like dental or castable resins for jewelry. 2. **Light Source**: - **Projector or UV LED**: DLP printers use a digital projector or an array of UV LEDs to project a patterned image of each l...
