eSUN 3D Printing Filament

eSUN is one of the world's most prominent manufacturers of 3D printing filaments, recognized for its invention of environmentally friendly PLA+ and its extensive range of specialized resins and engineering-grade polymers. The brand was established in Shenzhen, China, and has grown into a global leader within the additive manufacturing industry.

The company maintains its own dedicated research and development centers and manufacturing facilities, primarily located in the Xiaogan and Shenzhen regions. This vertical integration allows them to produce a massive volume of filament—such as PLA, PETG, ABS, and TPU—under strict quality control. Ownership remains with the founding company, Shenzhen Esun Industrial Co., Ltd., which continues to expand its reach through a vast network of international distributors and local warehouses across North America, Europe, and Asia.
