Since the advent of stereolithography in the 1980s, vat photopolymerization has grown to also include continuous liquid interface production (CLIP), solid ground curing (SGC), and direct light processing (DLP). All types of vat photopolymerization use special resins called photopolymers as the printing material.
Is photopolymerization a 3D printing approach?
Photopolymerization is a method that involves the solidification of photo-sensitive resin utilizing UV light. It is used by different 3D printing processes such as 3D Digital Light Processing (DLP), MultiJet printers, and Stereolithography (SLA).
Which radiations can be used for photopolymerization?
Photopolymerization is a light-induced reaction, which converts a liquid or gel monomer into a solid polymer. These reactions require the use of an appropriate photoinitiator, which is a light sensitive molecule that produces an active species upon irradiation with UV, visible, or infrared light.
Which vat polymerization technology is used in industry?
Stereolithography (SLA) is a common form of vat polymerization technology used for creating models, prototypes, injection molding patterns in a layer-by-layer fashion using photo polymer resins. It is a process in which light source causes chains of molecules to bond together to form a three-dimensional solid object.
Which additive manufacturing technique uses a tank of photopolymer that is cured hardened layer by layer using a laser?
Technology. Stereolithography is an additive manufacturing process that, in its most common form, works by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin.
