3D printer filaments

Filaments are the materials used in fused deposition modelling (FDM) 3D printers, where they are heated and extruded to form layers that create a three-dimensional object. The most common types of filaments include PLA (Polylactic Acid), ABS (Acrylonitrile Butadiene Styrene), PETG (Polyethylene Terephthalate Glycol), and TPU (Thermoplastic Polyurethane). Each type has distinct properties that cater to different printing needs.
