Professional desktop 3D printers vary in material offerings. Some are open-source material systems (meaning you can print with just about any third-party plastic filament), while others are closed with more limited material options.
Professional desktop 3D printers can also offer a variety of upgraded features, including: heated build chambers, material management, auto-bed leveling, dual-extrusion, variable nozzle diameters, precision mechanics, and high-speed extrusion heads.
This opens up countless use-cases for using professional desktop 3D printers, such as for prototyping, manufacturing end-use parts, creating custom forms and molds, and for building tooling, jigs and fixtures. Professional desktop 3D printers are used in industries like aerospace, automotive, architecture, education, healthcare and manufacturing.
