Real 2026 numbers: cost per gram, practical part examples, current printer prices and how much to charge per print without losing money.

Quick answer: a small PLA part (up to 50 g) costs between $1 and $3 to produce in 2026, including filament, energy and machine wear. In resin, a 30 ml miniature runs $2 to $5. Below is the full math â and at the end you can calculate the exact cost of your part.
PLA filament averages $15â25 per kilo in 2026, i.e. $0.015â0.025 per gram of material. But the real production cost â adding electricity, printer depreciation and a failure reserve â lands around $0.04 to $0.07 per gram.

FDM is cheaper per part: PLA goes a long way and there are no extra consumables. Resin costs more ($30â50 per liter, plus alcohol and FEP film), but delivers detail FDM can't match â which is why resin miniatures sell at higher margins.
The maker-market rule: total cost à 1.5 to 2.0 (50â100% margin). Add your modeling/finishing time and shipping. Custom or urgent parts justify higher multipliers.
