FDM printers are affordable, desktop 3D printers that use a process called fused deposition modeling. They heat and extrude thermoplastic filament, melting it to form layers of a 3D print. An FDM printer uses a spool of filament, feeding it through a heated print head which melts the material and deposits it onto a built plate. The printer produces multifaceted parts with resolutions around 100 microns. FDM printers require minimal setup and training to get started. They are versatile, compatible with various plastics and suitable for making prototypes, models, tools, and end-use parts. SUNLU FDM printers is the most affordable 3d printer in market.
