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 .
