Hello,

Help, please.
I want to calculate the weight of an object prior to printing.

I asked a couple of filament manufacturers but received no response.

I am trying to get my formulas right before hand.

density = mass/volume

volume = density * mass

The print area on printer is 300mm X 300mm X 420mm
Which gives a total volume of 37,800,000mm3 OR
3,780,000cm3.

The density of polycarbonate is 1.20g/cm3.

so, the weight of a full build would be:
3780000 * 1.20 = 4,536,000g

4,536,000g /453.592 = 10,000.17lbs (is that right??)

I don't think any of these hobby 3d printers could handle a 5ton print.
Where did I go wrong?

Thank You.
