Formlabs Form 4 Hardware Specifications
Build volume is taken from published slicer profiles. Power draw is a class-based estimate for this size and category of machine, not a manufacturer rating. Service life is a class-based assumption for this size and category of machine, not a manufacturer rating. The price shown is a hand-checked typical street price rather than an official MSRP.
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.
Motion system: Cartesian
A bedslinger moves the plate back and forth on the Y axis, which puts a practical ceiling on acceleration: past a certain speed the part itself becomes the thing being thrown around. For quoting that means print times scale fairly predictably with part height and layer count, but tall, narrow parts are the risk case — the taller the part, the more the moving bed works against it, and a toppled print late in a long job is the classic cause of an unbudgeted reprint.
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.
No heated chamber: what it can print
This machine has no actively heated chamber, so the bed is the only meaningful heater and the energy line on a typical job stays low. That is a materials constraint before it is a cost one: PLA, PETG and TPU are comfortable, while ABS, ASA and polycarbonate are warp-prone on large parts. If the machine is enclosed, passive heat retained from the bed helps considerably and many people run ABS successfully; on an open frame the failure rate on big parts in those materials is high enough that the usual 8–10% buffer understates the real risk.
What dominates the hourly rate
At this page’s default rate of $0.16/kWh, 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.
Owning a Formlabs machine
Budget-tier machines earn their price by leaving the tuning to you. Spare parts are cheap and widely available, which keeps repair costs down, but stock profiles are conservative and the first few weeks usually involve real setup time. If this is a production machine rather than a hobby one, count that setup as a one-off cost and keep an eye on the failure rate you actually observe — it is the number most likely to differ from the default assumed here.
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 runs at a typical draw of roughly 180 watts during active printing. Power draw is a class-based estimate for this size and category of machine, not a manufacturer rating. 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?
At a researched street price of $2625 and an assumed service life of 5,000 printing hours, the machine depreciation rate works out to roughly $0.525 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 estimated power consumption ($0.029/hr) and equipment depreciation ($0.525/hr), the baseline operating cost for the Formlabs Form 4 works out to roughly $0.55 per hour (excluding raw filament/resin and operator labor).
Is electricity or depreciation the bigger cost on the Formlabs Form 4?
At this page’s default rate of $0.16/kWh, 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?

How does the Formlabs Form 4's Cartesian motion system affect print cost?

For quoting that means print times scale fairly predictably with part height and layer count, but tall, narrow parts are the risk case — the taller the part, the more the moving bed works against it, and a toppled print late in a long job is the classic cause of an unbudgeted reprint.
Can the Formlabs Form 4 print ABS or polycarbonate without a heated chamber?
This machine has no actively heated chamber, so the bed is the only meaningful heater and the energy line on a typical job stays low. That is a materials constraint before it is a cost one: PLA, PETG and TPU are comfortable, while ABS, ASA and polycarbonate are warp-prone on large parts. If the machine is enclosed, passive heat retained from the bed helps considerably and many people run ABS successfully; on an open frame the failure rate on big parts in those materials is high enough that the usual 8–10% buffer understates the real risk.
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 the machine operating cost (~$0.55/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%).
