A desktop FFF printer made by Stratasys. Fused deposition modeling was developed by S. Scott Crump, co-founder of Stratasys, in 1988. [6] [7] With the 2009 expiration of the patent on this technology, [8] people could use this type of printing without paying Stratasys for the right to do so, opening up commercial, DIY, and open-source 3D printer applications.
In fused deposition modeling, the model or part is produced by extruding small beads or streams of material which harden immediately to form layers. A filament of thermoplastic or other low melting point material or mixture is fed into an extrusion nozzle head ( 3D printer extruder ), where the filament is heated to its melting temperature and ...
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter often being confused with the less common 3 mm. [3]
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.
Fused deposition modeling, also known as fused filament fabrication, uses a 3-axis robotic system that extrudes material, typically a thermoplastic, one thin layer at a time and progressively builds up a shape. Examples of machines that use this method are the Dimension 768 and the Ultimaker.
In addition to volumetric color by use of multiple print heads and colored binder, the 3D printing process is generally faster than other additive manufacturing technologies such as fused deposition modeling material jetting which require 100% of build and support material to be deposited at the desired resolution. In 3D printing, the bulk of ...
Fused Filament Fabrication (also known as Fused Deposition Modeling - FDM) describes the process of continuously extruding a line of thermoplastic material to form a three dimensional model. [1] The FFF process supports a variety of materials reaching from bio degradable ones like PLA to PETG, ABS and engineering grade materials like PEEK.
