Industrial SLA 3D printing resin

2020-11-12
Photocuring (photocuring) is the light-induced curing of monomer, oligomer, or polymeric substrates and is generally used in film formation processes. The technology is efficient, widely adaptable, economical, energy efficient and environmentally friendly. Light-sensitive resin coatings are the earliest example of successful large-scale application of light-curing technology in industry.


Photosensitive resin is UV resin, composed of polymer monomer and prepolymer, with light (ultraviolet) initiator or called photosensitizer, in a certain wavelength of ultraviolet light irradiation immediately cause polymerization reaction, complete curing, photosensitive resin is generally liquid, used to make high strength, high temperature, waterproof and other materials, photosensitive resin 3D printing commonly used in domestic and foreign mainstream SLA rapid prototyping equipment, most of the imports or domestic DLP desktop machine.


More than just polymer plastic, DSM Somos photosensitive resin focus on 3D printing

DSM Somos® photosensitive resins

Both DLP and SLA printing processes require specialized light-curing resins to achieve precise curing and reproduction of the printed model. In the 3D printing market, DSM has established itself as a leader in additive manufacturing through its Somos® resins business in the areas of stereolithography (SLA) and digital light processing (DLP), for which DSM has established a dedicated business unit: DSM Additive Manufacturing. Based on Somos' experience in the market, DSM also plans to cover the entire field of plastic printing materials, such as in the area of melt filament printing technology, for which DSM offers a growing portfolio of materials, including Novamid® polyamides and Arnitel® thermoplastic elastomers.
