How much does 3D printing cost in the UK? A workshop breakdown

A 3D print is not priced like a finished product on a shelf. You are paying for three real things: the plastic that goes into the part, the time the printer spends running, and a bit of handling to slice the file, load colours and pack it for post. Most workshops add a small minimum charge so a tiny keychain isn't a loss-making job.

That is the honest summary. The number you see at checkout is just those three inputs added up.

A rough range for small prints

For a part that fits in your palm — a bracket, a phone stand, a replacement knob, a small toy — you are usually somewhere between a few pounds and around twenty pounds in the UK. Bigger or more complex pieces (helmet shells, full vases, jigs that take half a day to print) climb from there.

Anyone giving you a flat "from £5" headline without seeing the file is either heavily rounding up or making a guess. The slicer needs the actual STL or 3MF to know how much plastic is in there and how long the printer will be running.

How a bureau actually works out the price

Every serious bureau in the UK does the same thing under the bonnet. You upload an STL or 3MF, software called a slicer chops it into layers and produces two numbers: filament grams and print time in hours and minutes. Those two numbers feed the quote.

For our own quoting we plug your file into the slicer set up for the chosen material, read the grams and the time off the result, and apply the per-gram and per-hour rates for that material. PLA, PETG, ABS, ASA, TPU and carbon-filled nylons all sit on slightly different multipliers because some are slower to print, harder on the hot end, or simply cost more per kilo. We don't guess weights from bounding boxes — that overcharges chunky parts and undercharges hollow ones.

If you want a feel for it before sending anything in: load your STL into a free slicer like OrcaSlicer or PrusaSlicer at 0.2 mm layer height and 15 percent infill. The grams and hours it spits out are roughly what a bureau will see.

What pushes the cost up

A few things move the dial more than people expect.

Infill is the biggest swing. Going from 15 percent to 80 percent infill on a hand-sized part can double the weight and the print time. Most decorative or display parts don't need it.

Walls and top layers matter almost as much. Bumping wall count from three to six on a chunky part adds a surprising amount of plastic.

Supports add real cost. If your model has overhangs steeper than around 45 degrees, the slicer prints throwaway scaffolding underneath that you snap off and bin. You paid for that plastic and that time, and you also paid for someone to pick it cleanly off the part.

Layer height is the lever in the other direction. A part at 0.28 mm will run roughly twice as fast as the same part at 0.12 mm. Coarser layers cost less but you can see them. For a structural bracket no one will care; for a tabletop miniature you probably will.

Material choice is the last big factor. PLA is the cheapest to run. PETG and ABS are usually a little dearer. Carbon-filled nylons and engineering blends can be several times the price per kilo, and they ask the printer to run harder.

DIY vs paying a workshop

If you already own a printer and you only want one of something, paying a bureau makes very little sense — you have already absorbed the cost of the hardware.

If you don't own one, the maths is trickier than it looks. A capable printer that can actually run PETG and ABS reliably is several hundred pounds before you add filament, an enclosure for the higher-temp materials, and the time you spend learning to slice properly. For a one-off bracket, that is wildly more expensive than just sending the file out.

The crossover is roughly this: under ten parts a year, sending it out is almost always cheaper. Over a few dozen a year, you start saving money owning a printer — but you are now also signing up for the maintenance.

Multi-colour prints cost more

If a model has two or more colours and you want them all printed (rather than painted on afterwards), the printer has to swap filament mid-print. On most multi-material systems that means purging the old colour through the nozzle until the new one is clean. That purge plastic is wasted, and it adds print time too.

We charge a small per-extra-slot fee on top of the base material price to cover that wasted plastic and the extra handling. A four-colour print is meaningfully dearer than a one-colour print of the same shape, and that is why.

If colour is decorative rather than functional, painting a single-colour print is sometimes the cheaper route. We can tell you which way round it sits when you upload the file.

Postage inside the UK

A small, light part — well under a hundred grams in a slim box — can usually go Royal Mail Letter Post or Large Letter Post. That is the cheapest tier, and we keep an eye on combined weight in your cart so you don't tip over the threshold by accident.

Larger or heavier parts move up to Tracked 48 or a small parcel service. Multiple items shipped together is almost always cheaper than ordering them in separate jobs. If postage looks high on something small, check whether the box dimensions or the combined cart weight are pushing it into the next tier.

How long does a print take?

Small parts often finish in a couple of hours of printer time. Hand-sized parts run a few hours to an afternoon. Larger or detailed jobs can run overnight. Multi-colour adds substantial time because of all the purges.

Print time is not the same as turnaround. Once your file is in the queue, we slice it, run it, let it cool properly, clean off supports, and pack it. We don't give a fixed promise on turnaround — anyone who does is bluffing — but most jobs ship within a few working days.

When to mail it in

Send us the STL or 3MF through the upload form and you will get a real quote based on the actual file, not a guess. We will tell you up-front if the model has a weakness that won't survive printing, if the colours you have picked will look odd in this material, or if a different infill and wall setup would give you a noticeably cheaper part without losing strength.

If you already have an idea of what you want but no model yet, drop us a message via /contact.html and we will talk you through the options before any printer touches plastic.
