3D Printing Costs Breakdown: Electricity, Filament & Maintenance (2026)
What 3D Printing Actually Costs (No Sugarcoating)
“But how much does it really cost to run?” — I get asked this constantly. My brother-in-law asked before he bought his first printer. My colleague at work asked. Bloke down the pub asked (after I showed him a print I’d made of his dog — long story).
Buying the printer is just the start. Filament, electricity, replacement bits, failed prints, and all the accessories you didn’t know you needed — it adds up. But here’s the good news: it adds up to a lot less than most people think. I’ve tracked every penny of my printing costs for the past two years, and I’ll give you the honest numbers.
1. The Printer Itself
Your upfront investment sets the baseline. Here’s what each tier gets you in 2026:
| Tier | Price Range | Example Printers | Best For |
|---|---|---|---|
| Budget FDM | £150-250 | Creality Ender-3 V3 SE, Anycubic Kobra 2 Neo | Beginners, hobby prints |
| Mid-range FDM | £250-500 | Bambu Lab A1, Creality K1C | Reliable daily printing |
| Premium FDM | £500-1,200 | Bambu Lab P1S, Prusa MK4S | Multi-material, high quality |
| Budget resin | £150-250 | Elegoo Mars 5, Anycubic Photon Mono | Miniatures, detailed models |
| Premium resin | £300-600 | Elegoo Saturn 4 Ultra, Phrozen Sonic Mini 8K | Professional detail work |
If you’re just getting started, our guides to the best printers under £200, under £500, and under £1,000 can help you choose.
Here’s how I think about it: A £300 printer that runs for 3 years averages about £8.30/month or 27p/day. Less than a coffee from Pret. And most printers last well beyond 3 years with basic maintenance — my original Ender 3 is still going strong after four years.
2. Filament Costs (FDM Printing)
Filament is your largest ongoing expense, and I won’t pretend otherwise. Here’s what each type costs on Amazon UK right now:
| Filament Type | Price per kg | Cost per 100g Print | Key Properties |
|---|---|---|---|
| PLA | £12-22 | £1.20-2.20 | Easy to print, biodegradable, good detail |
| PLA+ | £14-24 | £1.40-2.40 | Stronger PLA, slightly better heat resistance |
| PETG | £16-26 | £1.60-2.60 | Durable, chemical resistant, food-safe options |
| ABS | £14-24 | £1.40-2.40 | Heat resistant, impact tough, needs enclosure |
| TPU (flexible) | £18-30 | £1.80-3.00 | Rubber-like flexibility, phone cases, gaskets |
| ASA | £18-28 | £1.80-2.80 | UV resistant outdoor parts |
| Nylon (PA) | £25-45 | £2.50-4.50 | Very strong, wear resistant, hygroscopic |
| Carbon fibre PLA | £25-40 | £2.50-4.00 | Stiff, lightweight, wears brass nozzles |
| PAHT-CF (Nylon-CF) | £40-70 | £4.00-7.00 | Engineering-grade strength |

What prints actually cost in filament
These are real prints I’ve made, weighed on kitchen scales:
| Weight | PLA Cost | Time | |
|---|---|---|---|
| Cable clip | 5g | 8p | 15 min |
| Phone stand | 30g | 45p | 1.5 hrs |
| Small vase | 80g | £1.30 | 4 hrs |
| Raspberry Pi case | 45g | 70p | 2.5 hrs |
| 28mm miniature (FDM) | 8g | 13p | 45 min |
| Cosplay helmet | 350g | £5.60 | 20+ hrs |
| Full chess set | 500g | £8.00 | 30+ hrs |
At typical hobby usage (1-2 kg per month), you’re looking at £15-40/month on filament. That’s a couple of takeaways.
3. Resin Costs
If you’re printing miniatures, dental models, or jewellery patterns, resin is your consumable:
| Resin Type | Price per Litre | Cost per 10ml Print |
|---|---|---|
| Standard (grey/white) | £25-35 | 25-35p |
| Water-washable | £28-38 | 28-38p |
| ABS-like | £30-42 | 30-42p |
| Tough/engineering | £40-60 | 40-60p |
| Dental/castable | £60-120 | 60p-£1.20 |
But resin printing has hidden consumable costs that people forget about:
- IPA (isopropyl alcohol) for washing: ~£15-20 for 5 litres from Amazon UK, lasts 2-3 months of regular use
- Water-washable resin avoids IPA costs but is slightly more expensive per litre
- FEP/ACF film replacement: £5-15 every 30-80 prints (and you’ll know when it needs replacing — cloudy film = rubbish prints)
- Resin vat replacement: £15-30 every 6-12 months depending on how hard you push it
4. Electricity Costs
Right, let’s kill this myth. Electricity is the cost everyone worries about and nobody should. We have a detailed guide on 3D printer electricity usage, but here’s the short version:
UK electricity rate: 24.5p per kWh (Ofgem price cap, Q1 2026)
FDM printer power consumption
| Phase | Power Draw | Duration | Cost |
|---|---|---|---|
| Heating up | 200-350W | 2-5 min | 0.8-2.9p |
| Printing (bed + nozzle + motors) | 80-150W | Varies | 2.0-3.7p/hr |
| Idle/standby | 5-15W | — | 0.1-0.4p/hr |
What that actually means:
- 2-hour print: 4-7p electricity
- 8-hour print: 16-30p electricity
- 24-hour print: 47-88p electricity
I ran my printer for an eight-hour overnight print last week. It cost me about 20p in electricity. Twenty pence. I spend more than that on a Freddo.
Resin printer power consumption
| Phase | Power Draw | Cost per Hour |
|---|---|---|
| UV exposure + LCD | 30-80W | 0.7-2.0p |
| Lift motor | 10-20W | Included above |
| Standby | 3-8W | 0.1-0.2p |
Even cheaper than FDM. Resin printers sip electricity.
Annual electricity cost
| Usage Level | FDM Annual Cost | Resin Annual Cost |
|---|---|---|
| Light (10 hrs/week) | £10-19 | £4-10 |
| Moderate (30 hrs/week) | £31-58 | £11-31 |
| Heavy (60 hrs/week) | £63-115 | £22-63 |
Even heavy users spend less than £10/month on power. Stop worrying about electricity. It’s nothing.
5. Maintenance and Replacement Parts
Printers are mechanical devices with wear parts. Nothing lasts forever. But the costs are modest:
FDM maintenance costs
| Part | Cost | Replacement Interval |
|---|---|---|
| Brass nozzle (0.4mm) | £1-3 each | Every 200-500 hours |
| Hardened steel nozzle | £8-15 each | Every 1,000-2,000 hours |
| PEI/spring steel build plate | £15-30 | Every 12-24 months |
| Bowden tube (PTFE) | £3-8 | Every 6-12 months |
| Belts | £5-10 per set | Every 12-24 months |
| Silicone sock (hotend) | £2-5 for 3-pack | Every 3-6 months |
| Part cooling fan | £5-12 | Every 12-24 months (if needed) |
Annual maintenance budget: £20-60 for light use, £50-120 for heavy use. I’ve spent about £45 this year so far on maintenance parts, and I print a lot.
Resin maintenance costs
| Part | Cost | Replacement Interval |
|---|---|---|
| FEP/ACF film | £5-15 | Every 30-80 prints |
| Resin vat | £15-30 | Every 6-12 months |
| LCD screen | £30-70 | Every 1,000-2,000 hours |
| Build plate resurfacing | Free (sandpaper) | Every 3-6 months |
| Carbon filter | £5-10 | Every 2-3 months |
Annual maintenance budget: £40-100 for light use, £100-250 for heavy use.
6. Failed Prints (The One Nobody Mentions)
We need to talk about failures. Because they happen. To everyone.
Typical failure rates:
- Beginners: 20-30% of prints fail (don’t panic — this is normal)
- Intermediate users: 5-15% failure rate
- Experienced users: 2-5% failure rate
On a £5 print (materials + electricity), a 15% failure rate adds roughly 75p to your average cost per successful print. Over a year of moderate printing, failed prints might waste £20-60 in materials. Not devastating, but annoying.
I once had a 16-hour cosplay helmet fail at hour 14 because my filament had absorbed moisture overnight. That was about £4 in wasted PLA and an entire day lost. Lesson learned — I bought a filament dryer the next morning.
How to reduce failures:
- Calibrate your printer properly (one-time investment of patience)
- Use quality filament from known brands — avoid the ultra-cheap no-name stuff on Amazon, it’ll cost you more in failures than you save
- Dry filament before use (especially PETG, nylon, TPU)
- Clean and level the bed regularly
- Use appropriate slicer settings for each material
7. Accessories and Upgrades
You’ll accumulate tools. It’s inevitable. Here’s what you’ll actually need:
| Item | Cost | Priority |
|---|---|---|
| Filament dryer | £30-50 | High (essential for PETG/nylon) |
| Flush cutters | £5-10 | High |
| Scraper/spatula | £3-8 | High (often included with the printer) |
| Digital callipers | £8-15 | Medium (from Hobbycraft or Amazon UK) |
| Isopropyl alcohol (resin) | £15-20 per 5L | High (resin only) |
| Nitrile gloves (resin) | £8-12 per 100 | High (resin only) |
| Enclosure (ABS printing) | £30-80 (DIY) / £100-200 (bought) | Only if you’re printing ABS/ASA |
| Spare build plate | £15-30 | Low (nice to have) |
| LED work light | £10-20 | Low |
First-year accessories typically cost £50-100 on top of the printer itself. After that, you’re just replacing consumables.

| Total | £1,173-2,485 |
Cost per print hour: 38-80p
Can You Make Money With This?
At these costs? Yes, absolutely — if you’re selling the right things. Custom parts, miniatures, replacement components, and prototyping services all have healthy margins when your material costs are measured in pence.
Our guide on making money with a 3D printer covers the most viable business models and realistic income expectations.
How I Keep My Costs Down
- Buy filament in bulk — Multi-pack deals on Amazon UK drop the per-kg cost by 15-25%. I buy eSUN PLA+ in 3-packs and save about £5 per kilogram.
- Use appropriate infill — 15-20% infill is fine for most non-structural prints. Don’t default to 100% unless you’re making something load-bearing.
- Optimise part orientation — Reducing supports saves material and print time. A five-minute think before hitting “print” can save hours.
- Maintain your printer — A tuned printer fails less, wasting less material. Ten minutes of maintenance a week saves pounds in failed prints.
- Dry your filament — Moisture causes stringing, poor adhesion, and failures that waste material. A £35 SUNLU dryer pays for itself in a month.
- Print at the right resolution — Draft quality (0.28mm layers) is fine for functional parts. Don’t print everything at 0.12mm — you’ll use three times the electricity and twice the patience.
So What’s the Verdict?
3D printing is remarkably affordable once you’ve bought the printer. Electricity is nothing. Filament costs pennies per small print. Even maintenance is modest. The biggest hidden cost is failed prints — which you reduce by learning good practices and keeping your filament dry.
For most hobbyists, expect to spend £20-50 per month on consumables and maintenance after the initial investment. That’s less than a gym membership, less than a Netflix and Spotify subscription combined, and you end up with actual useful objects sitting on your desk. Not bad at all.
Frequently Asked Questions
How much does it cost to run a 3D printer per hour?
A typical FDM printer uses 50-150 watts, costing 1.2-3.7p per hour at UK electricity rates (24.5p/kWh as of early 2026). A resin printer uses 30-80 watts, costing about 0.7-2.0p per hour.
Is 3D printing cheaper than buying products?
For simple mass-produced items, buying is usually cheaper. But for custom parts, replacement components, miniatures, and prototypes, 3D printing saves significant money — especially at volume.
How much filament does a 3D print use?
A typical small print (phone stand, cable clip) uses 15-40g of filament, costing 25-70p. A larger print like a vase or helmet might use 200-500g, costing £3-10 in materials.
How often do I need to replace the nozzle?
Standard brass nozzles last 200-500+ print hours with PLA. Abrasive filaments (carbon fibre, glow-in-the-dark, wood-fill) wear nozzles much faster — consider a hardened steel nozzle (£8-15) if you use these regularly.
What's the cheapest filament that still gives good results?
eSUN PLA+ and Sunlu PLA are reliable budget options at £12-16 per kg. Avoid unbranded filament below £10/kg — inconsistent diameter causes jams and failed prints that waste more money than you save.
