3D printing filaments are long filament-like materials used in 3D printing technology, which are heated and extruded to build three-dimensional objects layer by layer. These filaments usually exist in the form of reels for easy storage and feeding into 3D printers.
Working Principle
The working principle of 3D printing filaments is based on fused deposition modeling (FDM) or fused filament fabrication (FFF). FDM is one of the most common 3D printing methods. As of now, FDM desktop 3D printing is accessible in nearly all industries where models and prototypes are needed (mass production, even home entertainment), and is increasingly being used to direct-manufacture some goods.
The basic principle of FDM technology is to melt thermoplastic materials such as ABS, PLA, PETG, PC, TPU and their composite materials at high temperature, extrude them through the hot melt nozzle, and then quickly solidify and solidify when cooled, and then form a three-dimensional object through the swing of the print head on the plane and the downward displacement of the heating plate.
Best Practices for Storing Filaments
According to the 3D printing filament type, improper storage environment may influence the printing characteristics, especially for environmentally sensitive materials. For optimal printing, make sure to keep 3D printing filaments in the correct storage.
You’ll want to use the new filaments in less than 12 months if possible, as this will help you get the best printing results, but if not, you have to take special care in storage to avoid damaging the filament. Filaments should always be stored in a cool place as possible; the optimal storage temperature is between 15 and 24°C (59 and 75°F).
Another important aspect of storage is humidity. All plastics absorb moisture over time, but the difference is the amount. While less hygroscopic materials such as ABS, PETG or TPU can only be dried before use to ensure optimal printing results, some hygroscopic plastics such as PLA, PVA and nylon absorb particularly high amounts of moisture. They do not fully regenerate after drying and are more prone to errors and problematic printing results. Therefore, we recommend that you store them in sealed containers with a desiccant.
