Size and print time
Your part costs in two currencies: grams of filament and hours on the machine. On a small part the plastic is the low-cost bit; machine hours and hands-on time are the larger share.

Quick answer
TL;DR The short answer
There is no single price for a 3D-printed part, and any service that quotes one before seeing your file is guessing. Cost comes down to six things: part size and print time, material, infill and walls, quantity, finishing, and turnaround. Send your file and an engineer returns one fixed UK quote within 6 hours, no minimum order.
The cost breakdown
What shapes the price of a part
Six levers decide the number on your quote. Understanding them helps you design for cost without giving up on strength.
Material
Material is a spectrum. PLA is the most economical; PETG, ABS and ASA add toughness, heat and UV resistance; carbon-fibre nylons like PA12-CF cost more and print slower. We right-size it and say when a lower grade answers your question.
Infill and walls
Inside the walls is a lattice, and its density drives cost. But the walls, not the infill, carry most real-world load, so we tune walls to the load rather than defaulting to dense infill.
Quantity and packing
Review and setup are paid once, so the per-unit price falls as the run grows and parts pack onto shared build plates. Quoting 50 parts in one run beats five small orders.
Finishing
As-printed is the lowest-cost finish. Support removal, sanding, painting and threaded inserts are hands-on labour, itemised so you pay only for the steps the part needs.
Turnaround
Standard pace is the baseline price. A rush job jumps the queue and costs more. Give us the real date and we can often sequence to hit it at the standard rate.

Material guide
Cost and properties at a glance
A quick comparison of the FDM materials we run most often. Relative cost is a guide only; your quote reflects the actual part.
| Material | Relative cost | Strength | Max temp (guide) | Best for |
|---|---|---|---|---|
| PLA | Low | Moderate | ~60°C | Prototypes, display, fit checks |
| PETG | Medium | High | ~80°C | Functional and mechanical parts |
| ABS | Medium | High | ~100°C | Enclosures and housings |
| ASA | Med-high | High | ~95°C | Outdoor and UV-exposed parts |
| PA12 nylon | High | Very high | ~100°C+ | Living hinges, tough wear parts |
| PA12-CF | High | Very high, stiff | ~100°C+ | Load-bearing brackets, jigs, metal-replacement |

A note from our workshop
Nine times out of ten the best-value route is not the lowest infill, it is the right material. We would rather tell you PETG saves a reprint than sell you a part that fails on the bench.

Frequently asked questions
How much does 3D printing cost in the UK?
There's no single price, because the cost depends on six things: the part's size and print time, the material, the infill and wall strategy, the quantity, the finishing, and the turnaround. A small PLA part testing a shape is inexpensive; a large, load-bearing carbon-fibre-nylon part costs considerably more, and the same geometry can vary widely depending on those choices. An engineer reviews your file and returns one fixed UK quote within 6 hours.
What makes a 3D print expensive?
Mostly size and print time. Material volume and machine-hours are the biggest drivers, and on small parts the plastic itself is usually the low-cost bit. Material grade is next: carbon-fibre nylons cost several times what PLA does and need drying, hardened nozzles and slower running. Infill density, finishing steps and rush turnaround then push the number further. Most of those are choices you control, which is why an engineering review usually finds savings.
Is 3D printing cheaper than injection moulding?
At low volumes, usually yes. A mould tool is a four-to-five-figure upfront cost before the first part, while 3D printing has no tooling, so you pay only for the parts. Until your run is big enough to pay that tool back, 3D printing is typically the cheaper route for a plastic part; above that the moulding maths starts to win, geometry depending. We'll tell you when your volumes are near that point rather than keep printing past it.
Why don't you have an instant-quote calculator?
Because a calculator multiplies your file's volume by a rate and can't see that a wall is too thin to trust, that a better orientation would halve the support material, or that a cheaper material would test your design just as well. An engineer reads every file we quote and returns a fixed price within 6 hours. The review is free, and it routinely saves more than it costs.
Does ordering more parts make each one cheaper?
Yes. The engineering review and setup are paid once, so the per-unit price falls as the run grows, and parts pack onto shared build plates and run back-to-back. That's the core saving in small-batch production: quoting 50 parts in one run beats quoting a handful five separate times.
Which material is the most cost-effective for 3D printing?
PLA is the most economical and is ideal for checking a shape or fit. PETG, ABS and ASA cost more and add toughness or heat and UV resistance. The carbon-fibre nylons, PA12-CF and PA6-CF, are the most expensive because they replace metal, and they carry running costs too, like drying and hardened nozzles. The most cost-effective choice is the lowest rung that genuinely answers your question, and the engineer review helps you find it.
How do I get a 3D printing quote?
Send an STL or STEP file through our quote form and tell us what the part has to do. An engineer reviews it, checking printability, material fit and the cost drivers above, and returns a fixed UK price within 6 hours. There's no minimum order; one part is a normal order. If you only have a sketch, our CAD design service can build the model first.
Is 3D printing cost-effective?
Yes, whenever you would otherwise pay for tooling you don't need. From one part up to a few hundred, 3D printing is almost always cheaper because there's no mould to make, and a tool is typically a four-to-five-figure upfront cost before the first part. At higher volumes the two routes get close, and above that injection moulding usually wins as the tooling cost spreads across the run. It's most cost-effective before a run is large enough to pay back a mould tool, for design iteration, and for geometry a mould can't make.
Why is 3D printing sometimes expensive?
Usually it's size and print time rather than the plastic: a tall or bulky part means many layers and long machine-hours, and on small parts the filament is the low-cost bit. After that it's material grade (carbon-fibre nylons cost several times what PLA does and need drying, hardened nozzles and slower running), high infill, hands-on finishing, and rush turnaround. Most of those are choices you control, which is why an engineer review usually finds savings before the part is printed.
