Are FDM printers only capable of printing PLA material?

Fused Deposition Modeling (FDM) printers are versatile and can work with a variety of thermoplastic materials beyond just PLA (Polylactic Acid). While PLA is one of the most popular materials due to its ease of use and good print quality, FDM printers can also print with materials such as ABS (Acrylonitrile Butadiene Styrene), PETG (Polyethylene Terephthalate Glycol), TPU (Thermoplastic Polyurethane), nylon, and more. Each of these materials has its own set of properties that make it suitable for specific applications, ranging from flexibility to temperature resistance.

The ability of an FDM printer to print different materials often depends on factors such as the printer's hotend temperature capabilities, nozzle size, and sometimes the inclusion of a heated bed or enclosure to help with material adhesion and warping. Therefore, the statement that FDM printers are limited to printing only PLA is incorrect, as they are a widely adaptable technology used in additive manufacturing for a range of materials.
