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.
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.
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.
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 ...

The first 3D rapid prototyping system relying on Fused Deposition Modeling (FDM) was made in April 1992 by Stratasys but the patent did not issue until June 9, 1992. Sanders Prototype, Inc introduced the first desktop inkjet 3D Printer (3DP) using an invention from August 4, 1992 (Helinski), Modelmaker 6Pro in late 1993 and then the larger ...
He also runs Fortus, RedEye on Demand, and Dimension Printing – business units of Stratasys. [ citation needed ] Crump managed the early work on another innovation used by FDM machines, the ABS plastic filament, which allows engineers to formulate fully functional parts that have up to 75% of the strength of an actual molded part.
