eSUN eBOX Filament Dryer

The eSUN eBOX is a specialized 3D printing accessory designed to store, dry, and weigh 3D printing filament. Filaments are hygroscopic, meaning they absorb moisture from the air, which can lead to poor print quality. The eBOX solves this by providing a temperature-controlled environment to remove moisture while simultaneously acting as a spool holder with an integrated scale for monitoring remaining material.

Originally developed by Shenzhen Esun Industrial Co., Ltd, the product is part of their extensive line of 3D printing materials and equipment. The brand has grown into a major international player in the additive manufacturing space. It is manufactured in China, where the company maintains its primary production facilities and research centers. Ownership remains with the founding Chinese parent company, which distributes these products globally through various e-commerce platforms and local 3D printing specialty retailers.
