Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. [1] Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the ...
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
In 2005, a system was development at the Drexel University, based on material extrusion, consisting of a mini-extruder with a single screw mounted on a high-precision positioning system, fed with bulk material in granulated form (pellets); [6] In 2015, a 3d printing machine was developed at Politecnico di Milano for MIM metals and CIM ceramics ...
FDM (fused deposition modeling) printing is one of the most popular types of 3D printing, [1] it is used throughout different engineering industries (medical, robotics, automotive) [1] and also has a great number of individual users that enjoy 3D-printing as a hobby. [2] FDM printing is so popular because it can produce near finished models of ...
An example of how 3D printing can be included in the design process is automotive design. [19] There, it is necessary to quickly test and verify a prototype to get the design approved for production. The reduced post-processing steps induced by the multi-material 3D printing technology result in a shorter fabrication time.
The process of transforming 3D printing filament into a 3D model The filament is fed into the FDM 3D printer. The thermoplastic is heated past its glass transition temperature inside the hotend. The filament is extruded and deposited by an extrusion head onto a build platform where it cools.

3D Systems manufactures stereolithography (SLA), fused deposition modeling (FDM), selective laser sintering (SLS), color-jet printing (CJP), multi-jet printing (MJP), and direct metal printing (DMP, a version of SLS that uses metal powder) systems. Each technology uses digital 3D data to create parts through an additive layer-by-layer process.
