Fused Deposition Modeling (FDM)
FDM is the most common process in 3D printing. The process works by melting a plastic filament which gets deposited over the platform forming one layer at a time according to the 3D data supplied to the printer. Each layer binds over the previous layers perfectly to get the desired output.
The main advantage of using the FDM process is the quality and sustainability of the materials. The Mechanical Properties of the materials also remain intact for a long time.
Application
- Sand casting patterns and molds with few detailing.
- Prototypes used in form, fit and function testing.
- ABS and Nylon based prototypes.
- Complex end-use parts.

Frequently Asked Questions
The melted material is extruded through the print nozzle in FDM. As the material is stacked, it becomes harder.
ABS, Polycarbonate, and ULTEMTM 9085 Resin are among the robust, engineering-grade materials used by FDM. FDM is capable of producing production parts and functioning prototypes with exceptional thermal and chemical resistance, as well as high strength-to-weight ratios.
