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:

TierPrice RangeExample PrintersBest For
Budget FDM£150-250Creality Ender-3 V3 SE, Anycubic Kobra 2 NeoBeginners, hobby prints
Mid-range FDM£250-500Bambu Lab A1, Creality K1CReliable daily printing
Premium FDM£500-1,200Bambu Lab P1S, Prusa MK4SMulti-material, high quality
Budget resin£150-250Elegoo Mars 5, Anycubic Photon MonoMiniatures, detailed models
Premium resin£300-600Elegoo Saturn 4 Ultra, Phrozen Sonic Mini 8KProfessional 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 TypePrice per kgCost per 100g PrintKey Properties
PLA£12-22£1.20-2.20Easy to print, biodegradable, good detail
PLA+£14-24£1.40-2.40Stronger PLA, slightly better heat resistance
PETG£16-26£1.60-2.60Durable, chemical resistant, food-safe options
ABS£14-24£1.40-2.40Heat resistant, impact tough, needs enclosure
TPU (flexible)£18-30£1.80-3.00Rubber-like flexibility, phone cases, gaskets
ASA£18-28£1.80-2.80UV resistant outdoor parts
Nylon (PA)£25-45£2.50-4.50Very strong, wear resistant, hygroscopic
Carbon fibre PLA£25-40£2.50-4.00Stiff, lightweight, wears brass nozzles
PAHT-CF (Nylon-CF)£40-70£4.00-7.00Engineering-grade strength

What prints actually cost in filament

These are real prints I’ve made, weighed on kitchen scales:

PrintWeightPLA CostTime
Cable clip5g8p15 min
Phone stand30g45p1.5 hrs
Small vase80g£1.304 hrs
Raspberry Pi case45g70p2.5 hrs
28mm miniature (FDM)8g13p45 min
Cosplay helmet350g£5.6020+ hrs
Full chess set500g£8.0030+ 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 TypePrice per LitreCost per 10ml Print
Standard (grey/white)£25-3525-35p
Water-washable£28-3828-38p
ABS-like£30-4230-42p
Tough/engineering£40-6040-60p
Dental/castable£60-12060p-£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

PhasePower DrawDurationCost
Heating up200-350W2-5 min0.8-2.9p
Printing (bed + nozzle + motors)80-150WVaries2.0-3.7p/hr
Idle/standby5-15W0.1-0.4p/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

PhasePower DrawCost per Hour
UV exposure + LCD30-80W0.7-2.0p
Lift motor10-20WIncluded above
Standby3-8W0.1-0.2p

Even cheaper than FDM. Resin printers sip electricity.

Annual electricity cost

Usage LevelFDM Annual CostResin 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

PartCostReplacement Interval
Brass nozzle (0.4mm)£1-3 eachEvery 200-500 hours
Hardened steel nozzle£8-15 eachEvery 1,000-2,000 hours
PEI/spring steel build plate£15-30Every 12-24 months
Bowden tube (PTFE)£3-8Every 6-12 months
Belts£5-10 per setEvery 12-24 months
Silicone sock (hotend)£2-5 for 3-packEvery 3-6 months
Part cooling fan£5-12Every 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

PartCostReplacement Interval
FEP/ACF film£5-15Every 30-80 prints
Resin vat£15-30Every 6-12 months
LCD screen£30-70Every 1,000-2,000 hours
Build plate resurfacingFree (sandpaper)Every 3-6 months
Carbon filter£5-10Every 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:

ItemCostPriority
Filament dryer£30-50High (essential for PETG/nylon)
Flush cutters£5-10High
Scraper/spatula£3-8High (often included with the printer)
Digital callipers£8-15Medium (from Hobbycraft or Amazon UK)
Isopropyl alcohol (resin)£15-20 per 5LHigh (resin only)
Nitrile gloves (resin)£8-12 per 100High (resin only)
Enclosure (ABS printing)£30-80 (DIY) / £100-200 (bought)Only if you’re printing ABS/ASA
Spare build plate£15-30Low (nice to have)
LED work light£10-20Low

First-year accessories typically cost £50-100 on top of the printer itself. After that, you’re just replacing consumables.

Total Cost of Ownership: Year 1

Right, let’s add it all up. Here’s what a realistic first year looks like:

Light hobby use (10 hours/week)

Printer (amortised over 3 years)£80-130
Filament (0.5-1 kg/month)£100-200
Electricity£10-19
Maintenance£20-40
Accessories (year 1)£50-80
Failed prints£15-30
Total£275-500

Cost per print hour: 53p-96p

Moderate use (30 hours/week)

CategoryAnnual Cost
Printer (amortised)£100-170
Filament (2-3 kg/month)£300-550
Electricity£31-58
Maintenance£50-100
Accessories£60-100
Failed prints£30-60
Total£571-1,038

Cost per print hour: 37-66p

Heavy/business use (60 hours/week)

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

  1. 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.
  2. 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.
  3. Optimise part orientation — Reducing supports saves material and print time. A five-minute think before hitting “print” can save hours.
  4. Maintain your printer — A tuned printer fails less, wasting less material. Ten minutes of maintenance a week saves pounds in failed prints.
  5. Dry your filament — Moisture causes stringing, poor adhesion, and failures that waste material. A £35 SUNLU dryer pays for itself in a month.
  6. 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.

FAQ

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.
