If you've ever tried to get a straight answer on 3D printing costs in the UK, you'll know how frustrating vague pricing can be. "It depends" is technically correct but not very useful when you need to budget a project. This guide breaks down exactly what drives the cost of 3D printing, what you can expect to pay for FDM, SLA, and SLS parts, and how to get an accurate price without picking up the phone.

What drives the cost of 3D printing?

Every quote for 3D printing comes down to three main variables: volume, material, and process. Understanding how each one affects price helps you design more cost-effective parts and choose the right technology for your budget.

Part volume

For most 3D printing technologies, cost scales roughly with the volume of material used. A larger, denser part uses more filament or resin, takes longer to print, and therefore costs more. This is why hollow or lattice-filled designs are often significantly cheaper than solid ones. Our InstaQuote tool calculates volume directly from your STL geometry to give you an instant price.

Material

Different materials have very different costs. Standard PLA filament for FDM is inexpensive; engineering-grade composite filaments (carbon fibre, Kevlar, Ultem) are considerably more. SLA resins cost more per litre than FDM filament, and SLS nylon powder is the most expensive of the three — reflecting the more complex equipment and post-processing involved.

Process

The technology you choose has the biggest impact on base cost:

FDM — lowest cost per cm³, suitable for most functional prototyping needs
SLA — mid-range cost, premium surface finish and accuracy
SLS — highest cost, but produces the strongest, most production-representative parts

FDM 3D printing costs

FDM is the most accessible 3D printing technology for good reason — it produces strong, functional parts at low cost in a wide range of thermoplastics.

Typical price range: £2–£30 for small to medium parts

What affects FDM pricing:

Infill density — 20% infill vs 100% solid can halve material usage and print time
Layer height — coarser layers (0.2–0.3 mm) are faster and cheaper; fine layers (0.1 mm) take longer
Support material — overhanging geometry requires support structures that increase material and post-processing time
Material grade — standard PLA is cheap; Nylon, Polycarbonate, and composite filaments cost more

FDM is the right choice when you need a physical part quickly and affordably, and precise surface finish is not critical.

SLA 3D printing costs

SLA delivers the finest surface finish and highest dimensional accuracy of any 3D printing process, which is reflected in slightly higher prices.

Typical price range: £5–£60 for small to medium parts

What affects SLA pricing:

Resin type — standard resin is cheapest; tough, flexible, castable, and biocompatible resins cost more
Wall thickness — thin-walled SLA parts use less resin than solid forms, keeping costs down
Post-processing — washing, UV curing, and finishing add labour cost
Surface treatment — painting, priming, or polishing adds to final cost

SLA is the right choice for visual prototypes, master patterns for moulding, dental models, and any application where surface quality matters more than mechanical toughness.

SLS 3D printing costs

SLS is the most capable but also the most expensive additive technology in common use. The powder-based process produces isotropic nylon parts without any support structures — enabling complex geometries that would be impossible in FDM.

Typical price range: £15–£150+ for small to medium parts

What affects SLS pricing:

Build packing density — SLS builds are most cost-efficient when multiple parts are nested into a single build. Standalone single parts carry the full machine cost
Material grade — standard Nylon 12 is cheapest; glass-filled and carbon-filled grades cost more
Post-processing — dyeing, bead-blasting, and painting add to cost
Part geometry — very dense, large parts cost more; intricate hollow geometries can be surprisingly affordable

SLS is the right choice for functional end-use parts, production-representative prototypes, and assemblies that require snap-fits, living hinges, or internal channels.

How to reduce your 3D printing costs

A few design decisions make a significant difference to price:

Reduce infill — for non-structural parts, 15–20% infill is usually sufficient
Shell the part — design hollow where possible rather than printing solid
Minimise supports — orient features to avoid overhangs above 45°
Right-size the part — printing slightly smaller (where tolerances allow) cuts material cost substantially
Choose the right technology — FDM for functional tests, SLA for aesthetics, SLS for mechanical performance
Batch your orders — combining multiple parts into one order reduces setup and shipping costs
