Understanding Formlabs Form 4 Running Costs
How SLA affects the numbers
Resin printers are unusual in that power draw barely moves with print size. The LCD panel and UV array run at an essentially fixed load whether the plate holds one part or fifty, so filling the build plate is close to free in energy terms. The consumable that actually matters is the LCD itself, which is a wear item measured in hundreds of hours.
Power draw: 180 W
A draw in the 100–250 W band is typical of open-frame desktop machines. Power is a genuine but secondary line item: worth including for accurate quoting, not worth optimizing. A standard 15 A household circuit will run several of these simultaneously without trouble.
What dominates the hourly rate
Depreciation is the larger share of this machine’s hourly rate, so the assumed lifespan drives your cost more than your electricity tariff does. If you service the machine well and expect to exceed the default hours, raise the lifespan figure in the calculator — it will lower your quoted cost more than any energy saving could.
Quoting at this price point
Industrial equipment recovers its cost only through utilization, and the depreciation figure here will overwhelm every other modeled input. Real-world ownership adds items this calculator does not cover: service contracts, calibration, trained operators, facility requirements, and consumables. Treat the output as a floor for machine time and layer your actual overhead on top.
Build volume: 5,250 cm³
The compact build envelope favors small, detailed parts and makes this machine well suited to batching many little components in a single job. Because the heated area is small, warm-up is quick and per-hour energy cost stays low — but larger parts will need splitting and joining, and that assembly time belongs in your labor estimate.

Frequently Asked Questions
How much electricity does the Formlabs Form 4 use?
The Formlabs Form 4 draws an average of 180 watts during active printing. At the standard residential electricity rate of $0.16 per kWh, running this printer costs approximately $0.029 per hour in power. A 10-hour print consumes ~1.80 kWh (about $0.29 in electricity).
What is the depreciation rate for the Formlabs Form 4?
With a retail MSRP of $4500 and an expected operational lifespan of 5,000 printing hours, the machine depreciation rate is $0.900 per operating hour. Including this in your print quotes ensures hardware replacement and maintenance costs are recovered.
What is the combined machine running cost per hour for the Formlabs Form 4?
Combining power consumption ($0.029/hr) and equipment depreciation ($0.900/hr), the total baseline operating cost for the Formlabs Form 4 is approximately $0.93 per hour (excluding raw filament/resin and operator labor).
Is electricity or depreciation the bigger cost on the Formlabs Form 4?
Depreciation is the larger share of this machine’s hourly rate, so the assumed lifespan drives your cost more than your electricity tariff does. If you service the machine well and expect to exceed the default hours, raise the lifespan figure in the calculator — it will lower your quoted cost more than any energy saving could.
What should I know about running the Formlabs Form 4 (SLA) commercially?
A draw in the 100–250 W band is typical of open-frame desktop machines. Power is a genuine but secondary line item: worth including for accurate quoting, not worth optimizing. A standard 15 A household circuit will run several of these simultaneously without trouble. Industrial equipment recovers its cost only through utilization, and the depreciation figure here will overwhelm every other modeled input. Real-world ownership adds items this calculator does not cover: service contracts, calibration, trained operators, facility requirements, and consumables. Treat the output as a floor for machine time and layer your actual overhead on top.
How do I calculate commercial quotes for 3D prints on a Formlabs Form 4?
To calculate a profitable quote: (1) calculate filament or resin consumed, (2) add machine operating cost ($0.93/hr × print time), (3) add labor preparation time, (4) apply an 8%–10% risk buffer for print failures, and (5) apply your target retail profit margin (typically 40%–60%).
Calculate maximum melt zone limits (mm³/s) to prevent underextrusion on high-speed prints.
