  • eBox
    The multi-function filament storage container eBOX has moisture-proof and dust-proof features. It is built to encase one roll of filament and in addition to its, the eBOX also integrates a weighing function....

  • While plastic may seem like a hardy material, 3D printing filaments can suffer adverse effects when exposed to elements such as moisture and dust—two things which are unfortunately common in most interior environments.

    Materials such as PVA, nylon, and PC, especially, have hygroscopic characteristics which means that they absorb water from the atmosphere. While this may be undetectable when looking at the roll of filament, the moisture absorption can begin to cause problems while printing, such as bubbles, inconsistent layers, and even bad surface finishes.

    To combat this problem, eSUN has developed the eBOX, a moisture and dust proof filament storage box which promises to protect your filaments.

    Each eBOX is built to encase one roll of filament (of either 1.75, 2.85, or 3 mm in diameter), which can be inserted directly into the box as there is no central axis rack. In addition to its moisture-proof and dust-proof features, the eBOX also integrates a weighing function. This, says the company, can provide realtime feedback to users about how much filament they have left on a roll.

    Essentially, when a roll of filament is placed inside the eBOX, a small LED-backlit LCD screen will display the filament’s weight. As the 3D printer progressively uses up the filament, the user can visualize how much filament is left by seeing the spool’s decreasing weight. This, in turn, will allow the user to switch out a roll when necessary and cut back on wasted filament.

    Aside from its weighing function, the eBOX storage container integrates a dust-free seal and a special drying bag slot, which enable users to keep their filaments safe from both compromising agents.

    Users not only have the option of protecting their filaments from moisture, but can use the eBOX to dry out filaments which may have been exposed to water molecules. That is, users can set a drying time and heating temperature for the eBOX, which will proceed to dry out the filament spool. Users can keep track of the box temperature by looking at the display screen.

    Finally, eSUN’s new eBOX product comes with an anti-skid pad. In a bid to make their product as efficient as possible, eSUN also integrated a feature which automatically turns the LCD display screen off to save power when not in use.
