Frequently Asked Questions

How do I calculate 3D printing filament cost and selling price?
Filament cost is calculated by dividing spool price by total spool weight and multiplying by model weight in grams. The selling price adds electricity cost, machine depreciation, labor time, packaging, and desired profit markup.
How does STL Volume and Model Weight estimation work?
The STL Volume Calculator parses binary and ASCII STL mesh files in your browser using signed tetrahedron volumes to calculate exact displacement in cubic centimeters (cm³) and grams based on material density.
What is volumetric flow rate and why does it cap print speed?
Volumetric flow rate (mm³/s) defines how fast a hotend can melt plastic. Max print speed is capped by: Max Speed = Max Volumetric Flow / (Layer Height × Line Width).
How do Bambu Lab AMS tools reduce purge waste?
Our Bambu Lab flush volume and purge calculators compute exact purge tower waste and optimize dark-to-light filament transition volumes to eliminate color bleed while saving up to 50% waste plastic.
