3D PRINTING FILAMENT




3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties, requiring different temperatures to print.

the most common filament types are acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). Most basic 3D printers are designed to exclusively use these filaments.
