SV3DPrinter and our friends together we are learning about 3D printing since 2014. 3D printing started long before SV3DPrinter. Now it’s time to take a brief test about the 3D printer and their anatomy.
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,”
An “extruder” is the thing that converts feed material to usable output, the entire machine at the highest level, or just the part that does the final output at the lowest level. So, in minimal terms, only the “hot-end” does any “extrusion”, specifically the nozzle.
The thing that pushes the filament should more properly be called a “feeder” or just “the feed”, and includes the entire path between the spool (material source) and the hot-end (conversion to output).
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.
Two different kinds of feeder are needed (generally a screw for beads vs. a hobbed gear for filament), but the hot-ends are remarkably similar. 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”.:)
