FDM （fused deposition modeling）printing creates custom parts by heating and extruding thermoplastics layer-by-layer.

While FDM is the most affordable 3D printing technology, it’s far more than a small-scale manufacturing solution. You can work with FDM using material  PLA, ABS, TPU, PETG, PEI, ABS-FR0, PA, PA-CF,PA-GF etc and a dimensional accuracy of ±0.5% with a lower limit of ±0.5 mm .
