Why are these parameters important?
Hardware $5000 + maintenance $500/year + 2000 hours lifespan → €2.75/hour depreciation. Small? No - for serial production it's €1000/month difference.
Real cost per operating hour - depreciation + maintenance + electricity
You bought a €1500 printer thinking every hour is 'free'? It isn't. Depreciation, maintenance, energy, consumables - they add up. This calculator computes the real cost per operating hour by technology (MEX, VAT, PBF, MJ, BJ, DED, LOM), machine price, maintenance, energy, and throughput. You also see break-even - how many hours the machine must run before it pays for itself. Covers 7 tech groups and 5 preset printers from Creality to Stratasys.
Available with the Pro plan (15 EUR per month). The printed book includes 3 months of Pro.



MEX (FDM/FGF), VAT (SLA/DLP/LCD), PBF (SLS/DMLS/SLM), MJ (PolyJet/NPJ), BJ (Binder Jetting), DED (WAAM/LENS), LOM (Sheet Lamination).
Creality Ender 3 Pro, Bambu Lab P1S, Prusa MK4S, Ultimaker S5, Stratasys F370 - 5 presets. Load one and the calculator configures itself.
Printer price, upgrades and accessories, annual maintenance, expected operating life.
Power (W), hours/year, electricity price, throughput (cm³/hour).
See exactly how many hours the printer must run before it pays for itself. For a Bambu A1 €420 at standard parameters - about 350-400 hours.
The calculator computes cost per printed cm³. Use this number directly in client pricing.
The calculator shows whether €1500 for a Bambu X1-Carbon makes sense for you.
Look at cost/hour for each machine. The lowest is your workhorse.
ROI of a new machine. Bambu A1 €420 → cost €0.20/hour → at €5/hour client rate → break-even at 90 hours.
What does a class printer cost for 100 students/year? The calculator computes exactly.
Hardware $5000 + maintenance $500/year + 2000 hours lifespan → €2.75/hour depreciation. Small? No - for serial production it's €1000/month difference.
