What is 3D filament?

3D filament is a material used in 3D printers to build three-dimensional objects layer by layer. It is a type of wire or wire spool that is heated and then fed through an extrusion head (nozzle), where it melts and is deposited on the print bed or the previous layers of the object.

The filament usually consists of thermoplastic polymers, such as polylactide (PLA) or acrylonitrile butadiene styrene (ABS), which are supplied in solid form. Other materials such as nylon, flexible polymers, wood fibers, metal composites, and even food-safe materials can also be used as filament.

Each type of filament has its own unique properties, such as strength, flexibility, heat resistance, solubility, gloss level, and color variation. These properties determine the suitability of the filament for different applications, ranging from functional prototypes and industrial parts to decorative objects and artworks.

The filament is usually stored on spools, which are available in different sizes depending on the 3D printer. It is sold in various diameters, usually 1.75 mm or 2.85 mm, to match the printer's specifications. Choosing the right filament for a project depends on the intended application, the desired properties of the final object, and compatibility with the 3D printer.

The use of 3D filament has opened the door to countless possibilities and applications, ranging from manufacturing and prototyping to architecture, fashion, medical industry, education, and much more. It offers an efficient and flexible way to create complex geometric shapes and promotes creativity and innovation in various disciplines.
