2. 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 ...

3. Prusa i3 - Wikipedia

   en.wikipedia.org/wiki/Prusa_i3

   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.

4. Fused filament fabrication - Wikipedia

   en.wikipedia.org/wiki/Fused_filament_fabrication

   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.

5. Ultimaker - Wikipedia

   Ultimaker is a 3D printer-manufacturing company based in the Netherlands, with offices and assembly lines in the US. [1] They make fused filament fabrication 3D printers, develop 3D printing software, and sell branded 3D printing materials. [2]

6. Comparison of 3D printers - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_3D_printers

   Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.

7. Hotend - Wikipedia

   en.wikipedia.org/wiki/Hotend

   The nozzle is an interchangeable tip attached to the hotend with a small diameter hole through which the melted filament is extruded. In desktop fused filament deposition printers, different sized nozzle holes can be used to balance between printing speed and precision. Common large sized ones (1.0mm) extrude more material per travel length ...
