Actual weight and cura weight for um3 print is different.

[ynagersheth 0]

Hi I have noticed that the weight of my printed part in cura and the actual weights are different. my part in cura is 267 grams and in actual it turns out to be 185-190 gms.

this is happening on the um3

I also print components on um2+ where the part weights are similar in cura and actual.

I am confused on how this is happening.

I use a 0.8mm nozzle on um2+ and a 0.4mm print core on the um3

I used UM nylon in both cases, plus pva on the UM3

Please help.

Thanks,

Yash.

Did you weight with the PVA?

Strange, i never tried to weight the prints and compare them but it should be pretty close

Yes.. but the PVA is just 7-8 grams of the total weight.

I use a 0.8 nozzle on my um2+ in which the weight in Cura and actual weight are pretty close.

But when I print a part in the um3 with a 0.4mm nozzle there is a large difference in cura and the actual weight. ( printing ultimaker nylon)

After submerging the part in a water tank with a pump (to remove pva faster) my nylon part became soft( squishy)....i can literally press the bottom of the part

Does Ultimaker nylon become soft due to water exposure?

Thanks!
