According to the comments and Thomas Sanladerer I am using some part to write my post so, we can learn more about the 3D printing and vocabulary,”
If you start with the plastic beads, then 3D printing can be viewed as a double-extrusion process: Once to make the thick filament, then again to make the thin lines used to form the printed part.
The extruder is the system/assembly from the feeder or driver to the hot end all encompassed. the feeder is a component of the extruder at the hot end is a component of the extruder.
V-slot bearings as an alternative to linear bearings.
Bridges are unsupported horizontal structures.
The “extruder” is a mechanism which gives a form to a material, pushing it through the hot hole. 3D printers, the “extruder” should include and the stepper motor with gears, and the hot end, and the Bowden’s tube, if any.
But I often see the term “extruder” is applied only to the motor, and do not include the hot end”.:)
The Felfil Evo filament extruder arrived and I was excited. I have a collection of failed prints and support material I am hoping to grind down and recycle into filament. Make ultra-smooth 3D prints filament at Home.”:)
