FDM (FFF) 3D Printing

A process of manufacturing an output by melting a thermoplastic plastic filament at a temperature above its melting point and stacking it layer by layer through a nozzle at a constant thickness.
 

Since products are formed by stacking, the marks of stacked layers and nozzle marks are more visible on the surface than with other 3D printing methods. The products are somewhat rough, so post-processing is required for a clean surface.

Advantages

✓ Relatively low manufacturing cost

✓ Can manufacture using various materials and colors

Disadvantages

✓ Lower quality and precision compared to other 3D printing technologies

✓ Difficulty of post-processing varies according to the material
