2. 3D printing filament - Wikipedia

   en.wikipedia.org/wiki/3D_printing_filament

   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] Filament consists of one ...

3. Extruder (3D printing) - Wikipedia

   en.wikipedia.org/wiki/Extruder_(3D_printing)

   A 3D printer extruder is a filament feeding mechanism used in many fused filament fabrication (FFF) 3D printers. There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely ...

   en.wikipedia.org/wiki/Material_extrusion-based...

   Printing: The process begins with printing the part using a filament containing metal powder bound in plastic. This filament, similar to that used in conventional FFF printers, is infused with metal. The printer deposits the metal-infused filament layer by layer, building up the shape of the part. These printed parts are referred to as "green ...

5. 3D printing processes - Wikipedia

   en.wikipedia.org/wiki/3D_printing_processes

   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 extruded onto a build table. More recently, fused pellet deposition (or fused particle deposition) has been developed, where particles or pellets of ...

6. Fused filament fabrication - Wikipedia

   en.wikipedia.org/wiki/Fused_filament_fabrication

   Hot extrusion of rods - In these types of 3d printing machines, the feedstock is in form of a rod instead of a filament. Since the rod is thicker than the filament, it can be pushed towards the hot end by means of a piston or rollers, applying a greater force and/or velocity compared to conventional FFF.

7. 3D printing - Wikipedia

   en.wikipedia.org/wiki/3D_printing

   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.
