FDM Technology builds parts in the same strong, stable plastics used in injection molding, CNC machining and other traditional manufacturing processes.
How FDM Works
3D printers that run on FDM Technology build parts layer-by-layer from the bottom up by heating and extruding thermoplastic filament. The process is simple:
1.Pre-processing: Build-preparation software slices and positions a 3D CAD file and calculates a path to extrude thermoplastic and any necessary support material.
2.Production: The 3D printer heats the thermoplastic to a semi-liquid state and deposits it in ultra-fine beads along the extrusion path. Where support or buffering is needed, the 3D printer deposits a removable material that acts as scaffolding.
3.Post-processing: The user breaks away support material or dissolves it in detergent and water, and the part is ready to use.
