I’m looking at a relatively new company, EIBOS, that provides a variety of 3D printer accessories.
The Shenzhen company launched only in 2020, and today markets several advanced filament drying systems, a resin post-processing system, as well as an extruder option. These are all products that can be found from many producers, but there was one product I hadn’t seen previously anywhere.
The product is the “EIBOS 3D Filament Vacuum Pump & Bag EURUS”. What is it, exactly?
It’s a system to vacuum-bag filament spools, and it works quite simply.
The EURUS system involves a specialized plastic double-seal bag, along with a vacuum pump. The bag includes a valve that prevents air from coming into the bag, but also acts as the mount point for the vacuum attachment.
To use EURUS, you simply place a spool into the bag, preferably with a dry desiccant, and screw on the valve. The vacuum pump is attached to the valve, and activated — it’s USB powered.
Air is pulled from the bag, sealing up tight against the spool and filament. This process takes about a minute to complete. Then, the pump is removed and you have a perfectly sealed filament bag for longer-term storage.
The bags can be reused, so you’d only need enough bags to handle your collection of intermittently used spools.
Desiccant is important to handle that last bit of moisture in the bag. However, desiccant that’s been lying around has no doubt levelled off to match the humidity of the surrounding environment. Always dry your desiccant packets in an oven before sealing them in with a spool.
This is an intriguing option for 3D printer operators who tend to collect partial spools. It’s common to have a number of spools in colors or materials with only a portion of the filament remaining.
These are often ignored, and then must be dried later before use, which can take some time. It might be a better idea to seal them up while they are still relatively dry, making them immediately useful when opening the bag later.
The system is priced starting at US$58 for the pump and ten sealable bags. It’s possible to buy a 20-bag option (US$78) or a 30-bag option (US$96).
While this product might not be particularly useful for materials that don’t absorb much moisture, like ABS or ASA, it could be extremely useful for more exotic engineering materials such as nylon, PETG, PVA, and others. The applications produced with those materials tend to have more stringent quality requirements, suggesting more importance to drying solutions.
If you’re suffering from loose spools that require longer-term storage in a dry environment, the EURUS could be an interesting approach.
