Question 1

What does this 3D print cost calculator include?

Accepted Answer

The free calculator covers: filament cost (weight × price per gram), electricity (print hours × watts × kWh rate), shipping (Royal Mail, Evri, US, EU, AU presets), platform fees (Etsy, eBay, Amazon, Shopify), and profit margin. G-code import fills weight and time automatically.

Question 2

How accurate is the 3D printing electricity cost calculation?

Accepted Answer

The calculator uses your printer's wattage, print time, and your local electricity rate to calculate exact kWh cost. You can set your exact rate or use country presets (UK ~£0.24/kWh, US ~$0.16/kWh, EU ~€0.28/kWh). Heat-up phase power is accounted for separately in advanced mode.

Question 3

Does this work as a Bambu Lab cost calculator?

Accepted Answer

Yes. Enter your Bambu printer's wattage (typically 350–1000W for X1C, P1S, A1 series), print time, and filament cost. The Pro version includes Bambu-specific printer presets in the Printer Library with auto-filled depreciation values.

Question 4

Can I use this as a Prusa calculator alternative?

Accepted Answer

Yes. LayerMath supports all FDM printers including Prusa MK4S, MINI+, and XL. It goes beyond basic filament cost to include electricity, labour, platform fees, and profit margin — making it a more complete pricing tool than most single-purpose calculators.
