3D Printer Filament Storage – How Is It Done Properly?

If you have moisture and mold in your home, you’re more likely to have respiratory problems, allergies, and a weak immune system. When you know the cause of the moisture, you can take steps to limit the moisture in the air.

Likewise, humidity is a natural enemy of filaments. Some materials have no humidity problem. Others, such as PVA or nylon, are very hygroscopic and absorb water after a very short time. The wet filament sizzles and is easy to recognize during printing, and the results are terrible. Therefore, it is particularly important to store filaments spools carefully and correctly.



Why Water Damages Thermoplastics

All plastics are polymers or copolymers. you’ll see that the long molecular strands that make up them are woven together when you look at polymers or copolymers under a high-intensity microscope, That means there’s plenty of space between and around the strands. Therefore, most polymers and copolymers are hygroscopic. Some filament materials, such as Nylon, are very sensitive to water. If they absorb only a little water, they can cause problems when printing.

How To Keep Your 3D Printer Filament Dry

Storing your 3D Printer Filament in an airtight container with a desiccant is the easiest way to settle this issue. Filament dry boxes work well, but they can be bulky.

when it comes to airtight, most people think of plastic containers and bags. For the most part, these are good short-term solutions.



Nevertheless, over time, plastic containers and bags become slightly permeable. This means that the longer your printing materials stay in plastic bags, the more water they absorb, .especially when you live in a humid climate. If you use a clear bag or box, a UV light will also reduce the strength of the filament over time.

Using high-quality Mylar bags or bags made of similar materials is a better solution to store your thermoplastic. Obviously, there is a layer of metal between two layers of plastic. This metal layer protects your printing material from any water vapor that permeates the plastic. So that your printing material produces a satisfactory result.




How You Know Your Printing Material Has Absorbed Water

Before printing, there are two simple ways to determine if your material is absorbing water. First, you can measure the diameter of the material itself. when a polymer absorbs water, it begins to grow in size. If the diameter of the filament increases by 10 percent or more, it most likely absorbs water.

Another way to determine whether a 3D Printer Filament absorbs water is to extrude a small amount of filament before printing. We’ve all probably been there: sitting by a fire, listening to its crackle. This is because the water in the wood is changed into steam when heated. The same phenomenon occurs when you extrude thermoplastic that has absorbed water. The heat from the print end causes the water in the plastic to expand and escape. You can hear hissing or popping and also see bubbles.

For every 3D printing lover, to select a proper 3D Printer is quite the most primary factor to think about. The better-quality machine you have, the finer models you are able to print. And yet, filament is of equal importance as the machine itself. Without a fine-quality filament, there will still exist a stumbling block in your printing works. In most recent years, 3D printing technology has gained its momentum and already come out of nowhere, with various innovation constantly boosting in this area. 3D printing filament, as the basic material for 3D printing works, directly or indirectly reflects the quality of the finished models. As a saying goes, a fine horse deserves a well-made saddle, so does a 3D printer. While pursuing the better promotion of the quality of FDM 3D Printer series, Geeetech also constantly perfect its series of filament. Here are some reviews on our Amazon shop from our dearest customers. For grabbing a further information of our filaments in stock o...
