How do you know how much material a print is going to consume?

[t-squareddesign 2]

When you open Cura, and put your CAD file on the building tray, is there any way to know how much material will be consumed after the print is complete?

I ask because I have a client I'm designing and 3d printing parts for, who is asking me to make random prints of various objects. And I would like to know how much to charge him.

When you slice the file, it will tell you how much length is being used.

Depending on the filament you use, that will vary in weight. Metal filled will weigh more and you actually get less in length because of this. 1.75 mm will be a different weight from 3.00 mm.

There are people here that have this down to a science, so be patient. Also, consider your competition and what else you may be providing as a service, model repair/creation, finishing, etc.

And, these are just the things that have been pointed out to me as I am new to this aspect myself.
