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 FLSun Q5 Running Costs
How FDM affects the numbers
FDM machines draw power in bursts rather than continuously. The hotend and heated bed cycle on and off to hold temperature, so the average figure used here sits well below the peak nameplate rating — the bed is usually the single largest consumer, which is why enclosed and large-bed machines cost noticeably more per hour to run.
Motion system: Delta
A delta drives three vertical towers in concert, giving a tall round build area and very fast travel on light parts. Two things matter for costing: the usable area is a circle, so the rectangular footprint you plan around is smaller than the headline diameter suggests, and effector calibration drifts more noticeably than on a gantry machine — budget for periodic recalibration time as labor rather than assuming it away.
Power draw: 250 W
Drawing 250 W or more puts this machine in heated-chamber or large-bed territory, where electricity becomes a real cost. Long prints on high-temperature materials push consumption higher still, since the bed and chamber work hardest maintaining temperature against ambient losses. If you run a farm, this is the tier where circuit capacity starts to constrain how many machines share a breaker.
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
In the budget tier the purchase price is low enough that depreciation per hour is almost negligible. The economics tend to favor simply running the machine hard and replacing it, rather than investing heavily in repairs. Where budget machines cost you is in time: more tuning, more failed prints, more hands-on attention — none of which appears on the electricity bill but all of which belongs in a commercial quote.
Owning a FLSun machine
Mid-tier makers compete on reliability rather than headline price, and it shows in the running cost more than the purchase price. Parts remain easy to source, firmware and profiles are maintained, and the failure rate on validated profiles is low enough that the machine spends more of its life actually printing. Higher utilization is what makes the depreciation figure on this page work in your favor.
Build volume: 8,000 cm³
A standard desktop envelope handles the large majority of hobby and small-commercial work without splitting parts. For quoting purposes this is the most predictable size class: heat-up time, energy draw, and failure risk all scale roughly with print duration rather than part geometry.

Frequently Asked Questions
How much electricity does the FLSun Q5 use?
The FLSun Q5 runs at a typical draw of roughly 250 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 $0.040 per hour in power. A 10-hour print consumes ~2.50 kWh (about $0.40 in electricity).
What is the depreciation rate for the FLSun Q5?
At a researched street price of $259 and an assumed service life of 3,500 printing hours, the machine depreciation rate works out to roughly $0.074 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 FLSun Q5?
Combining estimated power consumption ($0.040/hr) and equipment depreciation ($0.074/hr), the baseline operating cost for the FLSun Q5 works out to roughly $0.11 per hour (excluding raw filament/resin and operator labor).
Is electricity or depreciation the bigger cost on the FLSun Q5?
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 FLSun Q5 (FDM) commercially?
Drawing 250 W or more puts this machine in heated-chamber or large-bed territory, where electricity becomes a real cost. Long prints on high-temperature materials push consumption higher still, since the bed and chamber work hardest maintaining temperature against ambient losses. If you run a farm, this is the tier where circuit capacity starts to constrain how many machines share a breaker.

Where budget machines cost you is in time: more tuning, more failed prints, more hands-on attention — none of which appears on the electricity bill but all of which belongs in a commercial quote.
How does the FLSun Q5's Delta motion system affect print cost?
A delta drives three vertical towers in concert, giving a tall round build area and very fast travel on light parts. Two things matter for costing: the usable area is a circle, so the rectangular footprint you plan around is smaller than the headline diameter suggests, and effector calibration drifts more noticeably than on a gantry machine — budget for periodic recalibration time as labor rather than assuming it away.
Can the FLSun Q5 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 FLSun Q5?
To calculate a profitable quote: (1) calculate filament or resin consumed, (2) add the machine operating cost (~$0.11/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%).
