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 ...
With a direct-drive extruder, the motor pushing the filament is installed by the hotend and pushes the filament directly into the nozzle. Direct-drive designs have several advantages, and typically give better extrusion, faster retraction, are able to print more types of filaments, and can use a smaller and lighter motor due to the short ...
A print head similar to the one found in a 2D inkjet printer then applies the binder to the layer to solidify and bind it to the previous one. [2] Although binder jetting does not allow for multi-material support, there exist printers, which feature a second print head to apply pigment to the layer after the binder to allow for full color ...
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 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 ...
A key aspect of FDM printing is the use of specialized file formats that contain the data necessary to guide the printing process. These formats encode information about the 3D model, including its geometry, print settings and tool paths, [3] ensuring that the printer accurately recreates the digital design in physical form. Understanding the ...
