How to Calculate: Formula & Steps

Combines raw material cost per gram, electricity power draw, and machine depreciation wear per print hour, applying a safety margin for print failures.

Formula Used:

Total Cost = [Filament Weight (g) × (Spool $/1000)] + [(Power Watts / 1000) × Hours × $/kWh] + [(Machine $/Lifespan Hrs) × Hours]

Step-by-Step Calculation Example

A 150g PLA print taking 5 hours on a 150W printer using $20/kg filament and $0.15/kWh electricity costs $3.00 (filament) + $0.11 (power) + $0.83 (depreciation) = $3.94 total cost ($4.33 with 10% failure buffer).

Common Mistakes to Avoid

Forgetting to include electricity and machine wear depreciation.
Ignoring failed prints (misprints) in final cost buffers.

Practical Use Cases

Expert Tips

Factor in a 10% to 15% failure rate buffer to account for nozzle clogs and bed adhesion failures.

Frequently Asked Questions About 3D Printing Cost Calculator

How do I calculate 3D print cost per gram?

Divide your filament spool cost by the total spool weight in grams. For example, a 1,000g (1kg) spool of PLA costing $20 equals $0.02 per gram ($20 / 1,000g). Multiplied by a 150g print model, the material cost is $3.00.

How much electricity does a 3D printer use?

Most desktop FDM printers (Bambu Lab, Creality, Prusa) average between 100W and 250W during printing (higher during bed heating, lower during steady extrusion). Running a 150W printer for 10 hours at $0.15/kWh costs approximately $0.23 in electricity.

What profit margin should I charge for custom 3D printing services?

Commercial 3D print sellers on Etsy and local services typically charge a 100% to 300% markup on direct material and machine costs, plus an hourly labor rate ($20–$35/hr) for CAD design or post-processing.
