EIBOS EURUS — Vacuum Storage for Dry, Print-Ready Filament

The EIBOS EURUS is a simple, reusable vacuum storage system that keeps 3D printing filament dry between uses. A compact USB-powered pump draws air out of a durable sealed bag through a screw-on valve, collapsing the bag tight around the spool and locking out the moisture that causes stringing, bubbling, and brittle prints. Once sealed, filament stays dry for extended storage — no bulky dryer box required for spools you’re not actively using.

How It Works

Place your filament spool in the bag — add a desiccant pack at the same time for extra protection — seal the bag with the included clip, then screw the vacuum pump onto the bag’s suction valve and switch it on. The pump automatically extracts excess air from the bag, sealing it airtight around the spool in about a minute. Once evacuated, disconnect the pump and you have a compact, moisture-sealed filament package ready for long-term storage.

Reusable Bags — Buy Once, Use Repeatedly

The vacuum bags are made from thickened PA+PE material for durability and puncture resistance, and are designed to be reused across many spools over time. You only need enough bags to cover the spools you use intermittently — swap filament in and out as your projects change.

Long-Term Dry Storage

Once vacuum-sealed, filament can stay effectively dry for a year or more without needing to reopen the bag. This makes EURUS particularly useful for filaments you don’t use every day but want ready to go without a lengthy drying session the next time you reach for them — nylon, PETG, PVA, and other moisture-sensitive materials benefit the most.

Small But Powerful

The pump is USB powered and works from any standard USB port — a computer, laptop charger, or power bank — making it genuinely portable. There’s no mains adapter to lose track of and no dedicated power supply required.

Compatible with Almost Any Filament

The system is designed to work with 99% of common 3D printing filament spools across brands and materials — PLA, ABS, PETG, and specialty engineering filaments alike. While standard PLA and ABS absorb comparatively little moisture, EURUS delivers the most noticeable benefit for hygroscopic materials like nylon, PETG, and PVA that degrade quickly once exposed to humid air.
