The cost per gram formula
Divide the spool price by 1000 to get cost per gram. Multiply that by the grams used by the print. This gives the material line, not the final quote.
3D Price3D printing cost per gram
Turn filament grams into a real 3D print price.
Cost per gram is the easiest place to start, but it is not a complete selling price. Use it for material cost, then add the printer and business costs that make the job worth taking.
Inputs

When grams are useful
Cost per gram works well for comparing materials and explaining raw material cost. It is less useful for jobs with long print times, lots of support cleanup or high failure risk.
Add the missing cost lines
3D Price keeps material visible while adding electricity, wear, labor, packaging, platform fees and margin so the final price does not depend on plastic alone.
