PrintDry, a Canada-based 3D printing company, has launched a Kickstarter campaign for its new PrintDry Filament Container. Designed to keep your filaments dry and safe from moisture, the filament containers comes in packs of six for as little as CA$48 ($38).

If you are a maker that relies on FDM 3D printing, there is a good chance you will know the woes of filaments ruined by moisture. The tell-tale signs being poor surface quality, bubbles in your print, and inconsistent layers—all things you do not want to see after waiting hours for a part to be printed.

If you’ve found a DIY solution for keeping your filaments safe from moisture or have already invested in a commercial system for storing filaments, then you need not read on. But for those who are still looking for an affordable way to keep their PLA and ABS dry, Windsor-based company PrintDry claims to have the solution.

Readers might remember the Canadian company from a Kickstarter campaign last year which featured a novel device for drying your 3D printing filament. Aptly called the PrintDry Filament Dryer, the $99 machine uses simultaneous heating and venting systems to evaporate and remove any moisture from the filament.

PrintDry’s latest product takes a more preventative approach and, if it works as well as the company says it does, the filament container should effectively eliminate the need for the dryer system.

The PrintDry filament container looks, quite simply, like a rather large transparent tupperware, though it has been designed to fit a single spool of filament in it. Having a single spool per container, PrintDry explains, means that makers can select the filament they want without compromising their other filaments (which is a risk with using large airtight containers).

The 3D printing filament container, which has walls roughly 15 times the thickness of a zip-lock bag (a semi-reliable solution for keeping filaments out of moisture’s way), also features an airtight silicone seal and four clamps for securing the filament inside the container.

Helpfully, the filament containers are also made from transparent plastic, meaning that makers can easily locate and find the filament they are looking for—without the need for labels.

For extra precaution, PrintDry says it will include a number of desiccant bags which can be placed in the containers alongside the filament spools. Tests conducted on the humidity levels of the filament placed inside the container with five desiccant pouches showed promising results.

As the company explains, “The graph below shows the changes of the relative humidity (grey line) inside the container and the ambient humidity (red line) as the storage time increases.”

The Kickstarter campaign for PrintDry’s filament containers has already far surpassed its goal of CA$3,500 (it has currently raised CA$12,000) but it’s not too late to get a bite of the action. Early bird packs of six are still available for a pledge of CA$48 (roughly $38) and are expected to deliver as soon as December of this year.

Backers can also choose from a number of other rewards, including a dryer and container combo for $135.

For more filament storage options, Polymaker also recently released its PolyBox 3D printer accessory. The $70 dry storage box is designed to hold up to two spools and feeds directly into the 3D printer.

A good idea I think. Especially for more expensive filaments like Ultem and PEEK which absorb moisture very quickly.

First.. An eBay dehydrator for the 3D printing market with a huge markup. Now.. A cake box with no doubt a huge markup. Next.. A ziplock bag with "special" moisture repelling seals, and a bag of dessicant for only $20 a bag?

I have 10 rolls in a rubbermaid container with a crap load of silica packs I've gathered thru the year. Good enough.

Unless it has a metalized layer or multiple layers to prevent transmission through the walls of the container then they will leak and your filament will get wet.
