3D Printer Filament

Similar to needing paper and ink for an inkjet printer, you need filament for a 3D printer. 3D filament is the material that is heated and set in place to create your 3D print. This 3D printer plastic comes in various types, each with unique properties that affect strength, flexibility and durability. Some filaments are rigid and ideal for structural prints, while others are flexible for more dynamic applications.

Your choice of filament will be partially dictated by what your 3D printer can handle. So, if you are choosing a new 3D printer, you will want to consider what kinds of filament that printer can use and whether those will serve your creative needs.

When it comes to designing what your 3D printer will make, there are many 3D printing software programs—some of which are completely free. You may also want 3D printer accessories, like a 3D scanner to make a blueprint of existing physical objects or a filament dryer to set material. Proper 3D printer filament storage is also important to prevent moisture absorption, which can affect print quality and filament longevity.

Finding the best 3D printer filament for your project involves knowing your printer’s needs and understanding the kinds of 3D filament available. There are many, including ABS, PLA, Nylon, HIPS, PVA, PETG and TPU. Some of these materials need specialized 3D printer parts, like a bed enclosure, a cooling fan or a heated bed for slower cooling to reduce warping. All materials have pros and cons.

PLA filament is one of the most popular options because it does not require particularly high temperatures and does not easily warp. These qualities make it user-friendly and useful for many projects. It comes in numerous colors, black PLA and blue PLA being some of the most common.

Meanwhile, ABS filament is popular for its strength but is prone to warping. It requires a heated bed and excellent ventilation because it creates fumes. PETG filament also has high impact strength and great heat stability, but it can be tricky to work with. Each filament type has specific requirements and ideal use cases, so just like with all 3D printers and accessories, always research materials thoroughly before choosing.
