Fused deposition modeling, or FDM, is a rapid prototyping technology (aka rapid manufacturing) and is used to convert CAD drawings into physical parts. FDM Prototypes produce ABS Plastic Prototype Models, which have high strength and durability. For a full list of different Rapid Prototyping Technologies including FDM.
How FDM Works
The FDM fused deposition model process is additive which extrudes material in layers. A plastic filament is melted and extruded through a heated nozzle. The nozzle moves to produce a profile of the part then moves down and the next layer is built on top until the entire prototype model is fully built. The model is complete and requires no hardening. FDM is an excellent choice for any 3D Model that needs to closely represent the final product in strength and durability. We are currently using ABSplus material. CAD Models can be produced in about 24 hours depending on the size and complexity. Online price quotes are available for FDM parts.
FDM requires support during the Prototype Model building process and can increase the build time, parts such as architectural models can be built with the 3DP 3D Printing Prototype method which uses not support. Complex models with overhangs are not a good fit for FDM Fused Deposition Modeling.

Additional Information
FDM has been the Rapid Prototype technology of choice since 2002 because of its ease of use and high strength 3D CAD models and the flexibility of Plastic Prototypes such as drilling sanding and even chrome plating. FDM prototypes have become the preferred choice among designers, engineers, researchers, students and many other areas that use rapid prototyping. Fused Deposition Modeling is the most economical method to produce plastic prototypes and abs models.
