Print Cost Calculator

Estimate the real cost of a single 3D print — material, electricity, and a buffer for failed prints. Adjust every input to match your setup.

Material

Material cost ($/kg): $22

Printer (optional — sets power draw)

Object weight: 50g

Get this from your slicer, or estimate. A phone case is ~30g, a figurine ~50-100g.

Print time: 4h

Printer power draw: 300W

Electricity rate: $0.16/kWh

Failed print buffer: 10%

Beginners: 20%. Experienced: 5-10%.

Assumptions

Material weight from slicer (not including supports — add ~10-20% if your print needs them)
Electricity based on printer running at typical load, not peak
Failure buffer accounts for occasional failed prints and waste
