I've recently switched to PETG , and I'm using Cura as slicer and Ender 3 as printer.
I'm printing a model which Cura declares to be 35 g, but if I weigh the printed model it weighs 23 g.
I'm printing with just 1 line of skirt, so its weight is negligible on total weight. I've replaced the stock plastic extruder with a double gears metal extruder (3Dman 11 Dual Gear Extruder ).
I've also replaced the stock springs with metals ones.
I'm not having a quality problem, just I want to understand if this difference is caused by a bad configuration that could be improved.
Which are the corrections/checks that I need to do in my setup (both printer and Cura) for fixing this difference?
