How Much Does It Cost to Run a 3D Printer Per Month? (2026)
Most people only think about the filament. The real monthly cost of running a 3D printer - electricity, depreciation, maintenance, and consumables - is 3-5x higher than the filament alone. Here's the full breakdown by printer type, with real numbers for hobbyists, Etsy sellers, and small print farms. Use our 3D print cost calculator to plug in your own figures.
Monthly Running Cost - Quick Estimates
Hobbyist (1 printer, light use): £15-£35/month
Part-time Etsy seller (1 printer, moderate use): £35-£80/month
Full-time seller (1-2 printers, high use): £80-£180/month
Small print farm (4-6 printers): £250-£600/month
These include electricity, filament, depreciation, and maintenance. Excludes labour. UK rates used throughout - US figures typically 10-20% lower.
The 5 Cost Categories
A complete monthly running cost has five layers. Most people only track one or two. Here's what each covers and how much it typically adds up to.
1. Filament
The most visible cost but often not the largest. A hobbyist printing casually uses 0.5-1kg/month. An active Etsy seller might use 3-6kg/month. At £18-£22/kg for PLA, that's £9-£132/month in filament alone.
2. Electricity
Often underestimated. A Bambu A1 Mini draws ~120W printing, ~10W on standby. At UK rates (£0.245/kWh), 8 hours/day printing costs ~£0.235/day - around £7/month for light use, £42/month for a machine running 6 hours/day. See the full breakdown in our electricity cost guide.
3. Machine Depreciation
Your printer doesn't last forever. Spreading the purchase price over its lifespan gives you a monthly ownership cost. A £350 Bambu A1 Mini over 3 years = £9.72/month. A £1,099 Bambu P1S over 4 years = £22.90/month. This cost exists whether you print or not.
4. Consumables
Nozzles (replace every 3-6 months, £3-£15 each), build plates (last 6-18 months, £15-£40 each), PTFE tubes, lubricant, bed adhesion products. Budget £3-£8/month for a single printer on moderate use.
5. Failed Prints & Waste
Realistically 5-15% of filament used is wasted in failed prints, supports, purge lines, and calibration. On 3kg/month filament use at £0.020/g, that's £3-£9/month of wasted material before you even account for the time lost.
Monthly Cost by Printer Model (2026)
Based on moderate use: 4 hours/day printing, 20 days/month. Filament not included (varies by use). UK electricity rate £0.245/kWh.
| Printer | Price | Electricity/mo | Depreciation/mo | Consumables/mo | Total (excl. filament) |
|---|---|---|---|---|---|
| Bambu A1 Mini | ~£299 | £5.88 | £8.31 | £3-5 | £17-20 |
| Bambu A1 | ~£399 | £6.86 | £11.08 | £4-6 | £22-24 |
| Bambu P1S | ~£999 | £11.76 | £20.81 | £5-8 | £38-41 |
| Bambu X1C | ~£1,199 | £12.74 | £24.98 | £5-8 | £43-46 |
| Prusa MK4S | ~£799 | £9.80 | £16.65 | £4-7 | £31-34 |
| Creality K1 | ~£299 | £8.82 | £6.23 | £3-5 | £18-20 |
| Creality Ender 3 V3 SE | ~£159 | £5.88 | £3.31 | £3-4 | £12-14 |
| Voron 2.4 (self-built) | ~£700 | £14.70 | £14.58 | £5-8 | £34-38 |
Depreciation calculated over 3 years for consumer printers, 4 years for enclosed/pro models. Electricity based on 80W average draw (varies by model). US rates typically 20-30% lower. Use the electricity calculator for your exact wattage.
Real Monthly Cost Scenarios
Here's how the numbers stack up in three common situations.
Scenario 1: Casual Hobbyist
Bambu A1 Mini, printing 2-3 hours/day, ~1kg filament/month.
| Cost Item | Monthly (£) |
|---|---|
| Filament (1kg PLA @ £20/kg) | £20.00 |
| Electricity (2.5hr/day × 20 days × 0.12kWh × £0.245) | £2.94 |
| Depreciation (£299 ÷ 36 months) | £8.31 |
| Consumables (nozzle wear, build plate) | £3.00 |
| Failed prints / waste (est. 8% filament) | £1.60 |
| Total | £35.85 |
Filament is 56% of total cost. Depreciation alone is 23% - often ignored entirely by hobbyists.
Scenario 2: Part-Time Etsy Seller
Bambu P1S, printing 6 hours/day, ~4kg filament/month. Selling primarily PLA items.
| Cost Item | Monthly (£) |
|---|---|
| Filament (4kg PLA @ £20/kg) | £80.00 |
| Electricity (6hr/day × 25 days × 0.24kWh × £0.245) | £8.82 |
| Depreciation (£999 ÷ 48 months) | £20.81 |
| Consumables (nozzle, build plate, grease) | £6.00 |
| Failed prints / waste (est. 10%) | £8.00 |
| Packaging & shipping materials | £12.00 |
| Total | £135.63 |
To profit at this cost base, you need to generate at least £400-500/month in revenue just to cover costs and a minimum hourly rate. Use the free calculator to check your pricing.
Scenario 3: Small Print Farm (4 Printers)
4× Bambu P1S, running 10 hours/day, ~20kg filament/month total.
| Cost Item | Monthly (£) |
|---|---|
| Filament (20kg PLA @ £19/kg bulk) | £380.00 |
| Electricity (4 × 0.24kWh × 10hr × 26 days × £0.245) | £61.15 |
| Depreciation (4 × £999 ÷ 48 months) | £83.25 |
| Consumables × 4 machines | £24.00 |
| Failed prints / waste (est. 8%) | £30.40 |
| Packaging materials | £35.00 |
| Software / subscriptions | £15.00 |
| Total | £628.80 |
At this scale, labour becomes the dominant cost not listed here. See our print farm profit breakdown for the full P&L model.
The depreciation trap: A £999 printer feels free once you've paid for it. But it isn't - it's costing you ~£20.81/month in machine wear whether you use it or not. Sellers who ignore depreciation consistently underprice their work, then wonder why they can't afford to replace their printer when it dies. The Pro Calculator tracks depreciation per print automatically.
How to Reduce Your Monthly Running Cost
1. Buy filament in bulk
Buying 5-10kg at a time from Polymaker, eSUN, or Sunlu typically saves £2-4/kg vs. single-spool prices. On 4kg/month usage, that's £8-16/month saved - enough to cover your consumables budget entirely.
2. Print off-peak
If you're on a time-of-use electricity tariff (Octopus Go, E.ON Next Drive, etc.), printing overnight at 7-8p/kWh vs. 24p/kWh peak saves around 65% on your electricity bill. On a P1S running 6hr/day, that's £6-7/month saved.
3. Reduce failure rate
Each percentage point of failure rate is real money. At 4kg/month filament, dropping from 12% to 6% failure rate saves ~240g/month = ~£4.80. Dry filament storage, first-layer calibration, and bed adhesion consistency are the main levers.
4. Maintain your nozzle properly
A clogged or worn nozzle causes stringing, underextrusion, and failed prints - all of which waste filament. Replacing a £3 brass nozzle every 2-3 months is far cheaper than the filament wasted by a degraded one.
5. Price your running cost into every sale
The only sustainable way to manage running costs is to recover them per print. Use the free calculator to add electricity and depreciation to every cost estimate - not just filament. Most sellers who feel like they're "not making money" are simply not pricing these in.
UK vs US Running Costs
UK electricity rates (currently ~£0.245/kWh on standard tariff) are roughly 20-30% higher than the US national average (~$0.13/kWh). This makes electricity a bigger proportion of monthly running costs for UK-based sellers.
| Item | UK (£) | US ($) |
|---|---|---|
| Electricity rate | £0.245/kWh | $0.13/kWh |
| P1S electricity (6hr/day, 25 days) | ~£8.82 | ~$4.68 |
| PLA filament (per kg) | £18-£22 | $18-$24 |
| Bambu P1S printer price | ~£999 | ~$999 |
| Monthly depreciation (P1S, 48mo) | £20.81 | $20.81 |
Printer prices are similar in both markets. The main difference is electricity - UK sellers should factor this in more carefully when pricing prints for profitability.
FAQ
How much does it cost to run a 3D printer per month for a hobbyist?
For casual use (2-3 hours/day, ~1kg filament/month), expect £30-45/month on a machine like a Bambu A1 Mini. This covers filament, electricity, depreciation, and basic consumables. The figure rises significantly if you print more or use an enclosed printer.
Is electricity a big cost for 3D printing?
Less than most people fear for hobbyist use - £3-9/month for light use. It becomes significant at print farm scale (6+ hours/day across multiple machines), especially in the UK where electricity rates are higher than the US.
Should I include depreciation when pricing my prints?
Yes - always. Ignoring depreciation means your printer will eventually need replacing and you won't have the funds to do it. Spread the purchase price over 3-4 years and include it as a per-print cost. The Pro Calculator does this automatically once you set up your printer profile.
How do I calculate my exact monthly running cost?
Enter your actual wattage, electricity rate, filament use, and printer price into the free calculator. For the most complete picture including depreciation and failure rate, the Pro Calculator handles all five cost layers automatically.
How much filament does a typical Etsy seller use per month?
A part-time Etsy seller doing 30-60 orders/month on small-medium PLA items typically uses 3-6kg of filament per month. A full-time seller or small farm might use 15-30kg/month.
