eSUN was originally founded in Shenzhen in 2002, which is dedicated in R&D and industrialization of bio-degradable polymers, such as PLA and PCL. Adhering to Open Innovation with several top universities and institutions, eSUN own three R&D centers, which are syntheses, modification and application of polymers.

eSUN started to research 3D printing material in 2007. So far, eSUN successfully developed PLA, ABS, PVA (water soluble support filament), HIPS, PA, PCL, and PC filaments. Since 2015, eSUN has developed photopolymers for SLS/DLP/LCD 3D printing applications.
