How to Calculate 3D Printing Cost?

Calculating the true cost of a 3D print involves more than just filament weight. Our calculator considers:

Filament Cost: Based on density (PLA 1.24g/cm³, PETG 1.27g/cm³) and price per kg.
Electricity: Printer power consumption (kW) multiplied by print time.
Depreciation: Machine wear and tear per hour of operation.

FAQs: Cost per gram / per hour

Cost per gram: Enter price/kg and weight; the calculator shows material cost (price/1000 × grams).
Cost per hour: Electricity + depreciation are time-based; set hours/minutes and watts to see hourly impact.
Time estimator: Upload G-code (Cura/Prusa/Bambu) to auto-parse hours/minutes from file header/tail.

Can you make money with 3D printing?

Yes—use the Etsy toggle to include listing, transaction, and payment fees. Enter sale price + shipping, and we’ll return net profit so you can price with margin.

Frequently Asked Questions

How to calculate 3D printing cost per hour or per gram?

Use this formula: (Filament Weight × Price/g) + (Print Time × Power × Electricity Rate) + Machine Depreciation. The calculator above automates it and parses your G-code to get exact time/weight.

Is this a 3D print time estimator?

Yes. Drag & drop your .gcode from Cura, PrusaSlicer, or Bambu Studio and we read the slicer-estimated time from the file header/tail.

Can you make money doing 3D prints?

Absolutely. Enable Etsy Profit Calculator mode to factor platform fees and shipping, and see your net margin before listing.

Can you 3D print metal? What is the cost difference?

Metal printing (SLS/DMLS or metal-filled filaments) is much pricier than PLA/PETG because of material and post-processing costs. For plastics, use our calculator for quick estimates.

Electricity Cost

Most 3D printers (Ender 3, Prusa) use about 0.12 - 0.3 kWh per hour. A 10-hour print usually costs less than $0.20 in electricity.
