Some may remember my Polar 3D printer – I have issues with drive motor to arm gear ratios and associated print nozzle travel resolution at the moment. I intend fitting a sub 3Arcsec gearbox between the motor and current drive train – my choices are 10:1 and 20:1 ratios ( the current train is 8.5:1, so end result is 85:1 or 170:1) . The 20:1 (170:1) is my choice for resolution, but that places limits on nozzle linear rate -servo max speed, etc.

However, I am not sure what sort or linear lay-down rates users are achieving with their printers , therefore not sure what to aim for. Obviously it is subject to many factors – filament type, print temperatures, nozzle size and filament feeder feedrate capability, etc.

Given a good, solid printer, with a good feed head and basic 'fast print' filament, with 'basic print quality' ( all good enough for rapid prototyping) what linear axis rates are being achieved?

(EDIT – I did not post a 3D print intro in the title, as I posted this in the 3D print forum section – thought it would add that for me!)

Thank you Moderator, for the 3D insert…!
