calculation of E

Recommended Posts

Posted · calculation of E

just checking my math here -

if I print a 10x10x5mm 100% solid fill object, with 2 perimeter lines,

would I not expect the volume of PLA extruded to be 500mm^3 ?

because Cura tells me I extruded 83mm of filament, at 2.85mm diameter and pi*(2.85/2)^2 * 83 = 529mm^3

so does that mean I'm overextruding, or do I not expect the numbers to match up?

If it does, presumably I can adjust E very slightly accordingly.. ?

Cura does some overextrusion because of corners and infill-perimeter overlap, that could explain the extra 30mm3

that's true I forgot about that 15% overlap. so doesn't that mean there should be even more material here than I expect - where did it all go then? when I measure the part it's 10.01x10.04x4.87mm?

'product shrinkage' ??
