Maximum Volumetric Output for tool head add-ons
Closed, ResolvedPublic

Description

@anolen We need to determine the maximum volumetric output of the Standard v2 Aerostruder for Mini 2. Lets use PLA as the base material, if we want to get a second we can also do ABS.

We should be able to determine this by maximum extrusion speed at temperature before stripping out.

adding @tutley if you need a hand.

@karrad I found with the standard aerostruder v2 for mini 2 with a 0.5mm nozzle, the max extrusion feedrate for PLA at 205C is F130. Anything beyond that and the motor starts to skip a bit. So that's 130mm/min or 2.16mm/sec.

Then the volumetric output of the hotend is Pi*(2.85 mm/2)^2*2.1666666 mm/s = 13.82mm^3/s

This will change depending on the motor size, motor current, nozzle diameter, and temperature.

@tutley Awesome, thanks! Going to close this out, and cross post in T2540 for the spec sheet

Volumetric Output:

0.25mm max build speed 8.5mm^3/s (ACHEMON) with Polylite PLA at 205C
0.5mm max build speed 13.8mm^3/s (STANDARD) with Polylite PLA at 205C
0.8mm max build speed 40.38mm^3/s (BANDED) with Polylite PLA at 220C
1.2mm max build speed 45.69mm^3/s (DINGY) with Polylite PLA at 220C

For future spec sheets

Some more info on this:
0.25mm max build speed 8.5mm^3/s (ACHEMON) with Polylite PLA at 205C (F80)
0.5mm max build speed 13.8mm^3/s (STANDARD) with Polylite PLA at 205C (F130)
0.8mm max build speed 40.38mm^3/s (BANDED) with Polylite PLA at 220C (F380)
1.2mm max build speed 45.69mm^3/s (DINGY) with Polylite PLA at 220C (F430)
