What this calculation means
The value is derived from the uploaded mesh geometry. Interpreting the design unit correctly matters because volume changes with the cube of the selected unit.
How it works
Volume is calculated from the enclosed mesh surface after you choose the unit used by the model coordinates.
What the results mean
Volume is most reliable for a closed, consistently oriented mesh. Material weight is an estimate using the selected density and simplified infill assumptions.
FAQ
Why can volume be unreliable?
Holes, open surfaces and inconsistent triangle orientation can prevent a dependable enclosed-volume calculation.
Is material weight exact?
No. Slicer settings, shells, supports and infill pattern change actual use.
