Unlike other 3D printing technologies, fused deposition modeling (FDM)  or fused filament fabrication (FFF) prints objects, items, or models by  depositing melted filament continuously and selectively. The FDM 3D  printers are designed with heated nozzles.As highlighted by several market studies,  FDM or FFM is currently one of the most widely used 3D printing  technologies. Many manufactures opt for this 3D printing technology to  produce basic proof-of-concept models without increasing time and cost.  The option to choose from a wide range of FDM materials further helps  engineers to produce models and objects according to precise business  requirements. We can identify the popularity of this 3D printing  technology based on a slew of FDM 3D printing applications and use  cases.
