[SOLVED] upgrading motor/heater for faster extrusion?

Heater definitely does not need to be upgraded, and should not be upgraded for safety reasons. A more powerful heater will result in thermal decomposition of the material - with certainly if the controller fails, and possibly even if not.

The beta motor is 50% faster and available in the store:

Because of the PID controller - it will turn the heater on for longer.

Just like when you're printing with your 3D printer at slow speeds versus fast speeds.

You would need to be extruding roughly 5 times faster than normal to need a larger heater.

Most of the heat goes to the air, not the plastic.

50-100% faster? No problem. You'll need a beta motor for 50% faster, and to overvolt it/add cooling for 100% faster.

500% faster? You'll need a much more powerful motor (expensive), possibly a new feedscrew/barrel (very expensive), and then you'll battle diameter tolerance problems from unstable viscoelastic flow. Industrial extruders get around the latter by either using very expensive laser mics, or complicated die-draw equipment.

I designed the Filastruder to be as inexpensive as possible but still extrude quality filament faster than 1-2 printers could use it up. Going much faster gets expensive quickly.

Running a polymer at a temperature that overloads the machine to the point that it would bend the barrel would definitely break gears in the gearbox, no real surprise there. I do have some spare gears, email me through the Filastruder contact form if you need some.
