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]
MakerBot Industries, LLC was an American desktop 3D printer manufacturer company headquartered in New York City.It was founded in January 2009 by Bre Pettis, Adam Mayer, and Zach "Hoeken" Smith to build on the early progress of the RepRap Project.
Josef Průša was a core developer of the RepRap project who had previously developed a PCB heated "print bed". He adapted and simplified the RepRap Mendel design, reducing the time to print 3D plastic parts from 20 to 10 hours, changing to the use of two Z-axis motors to simplify the frame, and including 3D printed bushings in place of regular bearings.
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 used in filament 3D printers is the direct-drive extruder, which sits closer to the extruder hot end.
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 ...
When Makerbot Industries removed firearms-related 3D Printable files at the public repository Thingiverse in December 2012, open-source software entrepreneurs Cody Wilson and Ashley Tyson launched DEFCAD as a companion site to publicly host the removed files.
TPU is one thermoplastic elastomer used in fused filament deposition (FFD) 3D printing. The absence of warping and lack of need for primer makes it an ideal filament for 3D printers when objects need to be flexible and elastic. Since TPU is a thermoplastic, it can be melted by the 3D printer's hotend, printed, then cooled into an elastic solid.
Because the fibers are contained in a filament, the printer is capable of freely orienting the fibers [29] within the print plane. The X7 (previously called Mark X) was released at the end of 2016 with accuracy improvements, a stiffer gantry, and larger build volume of 330mm x 270mm x 200mm, 2.5 times larger than that of the Mark Two.
