3D Print Cost Calculator
Estimate filament, electricity and optional machine wear from the weight and time in your slicer. This is a personal print estimate, not a model's solid volume or a selling price.
Start with your slicer.
Enter your print details and rates, then calculate to see the total and breakdown.
OPTIONAL STARTING POINTS
Try an example.
Illustrative inputs, not measured prints or standard model costs.
Examples fill only weight and time; your entered rates stay unchanged. Missing rates receive clearly labelled illustrative values.

01
Slice your model
Use the final filament weight and estimated print time from your slicer. Include generated supports and other printed material.
02
Add your own rates
Enter your spool price, net filament weight and electricity rate. Use measured average power where possible.
03
See what adds up
Review material and electricity separately. Add wear or a contingency allowance only if you want them included.
Reduce cost, without guessing.
Compare in the slicer
Try a different orientation or support strategy, re-slice, then compare the new weight and time.
Keep strength in mind
Lower infill may use less material. Check whether the part still suits its load and purpose.
Measure your printer
A plug-in energy meter can help replace a rough wattage estimate with your own observations.
A few useful answers.
How much does 3D printing cost?
It depends on material used, print time and your own rates. This personal FDM estimate adds filament and electricity, plus any machine wear or contingency you choose. It is not a commercial quote.
Why use slicer data instead of uploading an STL?
A solid model's volume does not describe FDM walls, infill, supports or toolpaths. This calculator uses manually entered slicer weight and time; it does not parse STL or G-code files.
What power value should I enter?
Use estimated or measured average power over the print, in watts. Rated maximum power is not the same as average draw. Electricity equals watts divided by 1,000, multiplied by hours and your price per kWh.
Is contingency the same as a failure rate?
No. It is an optional percentage added to filament, electricity and selected wear costs. It does not model the probability or cost of repeated failures.
Can I use this to set a customer price?
Not on its own. Labor, design work, shipping, tax, profit and commercial overhead are outside this personal estimate. The calculator uses USD throughout and does not convert currencies.
