All 3D printer filaments are kept as dry as possible, but some filaments are more sensitive to humidity than others. The best solution is drying oven; A sealed filament container, usually containing a desiccant. But at a critical juncture, [spacefan]’s fast and dirty $0 drybox solution is encouraging, at least in terms of simplicity.
The only part added is this 3D printing accessory.
[spacefan]’s solution creates a sealed environment for a single volume using the packaging material of the filament roll itself and a single 3D printing unit. The roll is stored in a plastic bag (which may be the same as the sealed plastic bag), and the filament is discharged through a small hole and a 3D printing accessory, which also uses a little spare PTFE tube. This box can be used as a convenient container. It’s not as many as other DIY dry box solutions, but it’s really simple.
Although we appreciate this idea, this design will certainly bring great friction to the slide valve itself. Pulling the filament from the spool requires a lot of extra work. The spool needs to rotate in the bag and box. These extra work will be completed by the extruder of 3D printer. Ideally, the extruder should work as little as possible. The reuse of materials is a good idea, but in our opinion, this idea does need some improvement.
What do you think? Is it useful at a critical juncture or needs to be changed? Would it help to add a spindle to support the spool valve? Let us know what you think in the comments.
