Choosing a 3D printing service in the UK: process, material and what to send
To choose a 3D printing service in the UK, pick the process from size, detail and strength, then the material from heat, wear and flex, then the supplier from what they check and who you talk to. HenleyPrint3D offers FDM, SLA, SLS and PolyJet from Devon, with lead times from 1 calendar day.

Key takeaways
- Size usually decides: FDM to 1000 mm, SLA to 350 x 250 x 250 mm, SLS to 165 x 165 x 300 mm.
- Detail points to SLA or PolyJet; uniform strength and complex geometry point to SLS.
- Lead time starts at 1 calendar day (SLS from 2). Finishing, quantity and transit add time.
- Send STEP, quantity, material, finish and deadline. A drawing marks critical dimensions.
- Compare suppliers on inspection, records and contact, not only headline price.

Worth knowing
This is a decision guide. The linked pages carry the specifications.
Process comparison: size, tolerance and lead time
| Process | Build volume | Tolerance | Lead time from | Best for |
|---|---|---|---|---|
| FDM | 1000 × 1000 × 1000 mm | ±0.5% (min ±0.3 mm) | 1 calendar day | Large, tough functional parts, jigs and fixtures |
| SLA | 350 x 250 x 250 mm | ±0.5% (min ±0.1 mm) | 1 calendar day | Fine detail and smooth surfaces; 10 micron |
| SLS | 165 x 165 x 300 mm | ±0.3% (min ±0.3 mm) | 2 calendar days | Supportless PA12 nylon and complex geometry |
| PolyJet | See service page | 16 to 30 micron layers | See service page | Multi-material, multi-colour, fine detail |
The services are on one page each: FDM, SLA, SLS and PolyJet. For a head-to-head comparison, read FDM vs SLA vs SLS vs PolyJet and how to choose a 3D printing process.
Worked scenarios
| Your part | Reasoning | Likely route |
|---|---|---|
| Outdoor bracket, 80 mm, 20 pieces, needs to take knocks | Small, repeated, tough, UV exposure | SLS PA12, or FDM ASA if the part needs UV stability |
| Duct 1.2 m long | Longer than every build volume, including FDM at 1000 mm; split once and bond | FDM in sections |
| Detailed 40 mm display or master model | Fine detail and smooth surface matter more than toughness | SLA |
| Assembly jig 600 x 400 mm | Large, no tooling, edited often | FDM PETG, with inserts at fixings |
| Multi-colour or multi-material prototype | Needs several materials in one part | PolyJet; see the service page for specification |
| Flexible seal or grip | Rubber-like behaviour | TPU in FDM, or a flexible photopolymer |
Rule of thumb: size sets which processes are possible, detail decides between FDM and SLA/PolyJet, and load and heat decide the material. If more than one process fits, the choice usually comes down to surface finish, lead time and quantity.
Material selection by requirement
| You need | Material | Process |
|---|---|---|
| Quick form-fit model | PLA | FDM |
| General functional part | PETG (default) | FDM |
| Outdoor use, around 100 °C | ASA | FDM |
| Wear or moving parts | Nylon PA12 | FDM or SLS |
| Stiff, light structure | Carbon-fibre PETG | FDM |
| Flexible, rubber-like | TPU | FDM |
| Flame rating, high heat | ULTEM 9085 or 1010, on request | Industrial FDM |
| Finest detail | SLA resins | SLA |
Start from the failure mode: heat, wear, impact, UV or flex. The 3D printing materials guide covers this in more detail, and the materials explorer lists every grade we print.
Lead times
FDM and SLA start from 1 calendar day and SLS from 2. Queue and finishing take most of the time, and the build is usually the shortest stage; see how a 3D printing lead time breaks down. International orders include shipping in the quote, and expedited air freight is available for time-critical orders. Check whether any quote counts calendar or working days.
Types of supplier: marketplace, bureau and engineering partner
"3D printing service" covers three business models, and each needs different questions.
| Type | Typical strength | Typical limit |
|---|---|---|
| Online marketplace or aggregator | Instant prices, wide choice of machines | The supplier making your part may change; limited engineering conversation |
| Print bureau | Consistent machines and fast turnaround | May not review design or advise on material |
| Engineering partner | Reviews each file, advises on process and design, supports repeat and low-volume production | Quotes are per file rather than a catalogue price |
HenleyPrint3D works as an engineering partner: every order is reviewed by an engineer, and repeat orders are built from the same recorded settings. For a longer comparison, see online 3D printing platforms vs a UK engineering partner, or, for named services, how Protolabs, Hubs and Craftcloud compare.
Red flags when choosing a supplier
- No named person or direct contact for questions.
- Lead time quoted with no statement of what it includes.
- A certificate claimed without a certificate number or scope you can verify.
- No answer to how a repeat order is matched to the first batch.
- Promises of every material and process with no limits stated. Every service has limits; look for a supplier that names them.
- No confidentiality route for sensitive designs.
Certification and confidentiality
Ask what quality system a supplier has and whether it is certified or working towards a standard. HenleyPrint3D is working towards ISO 9001 certification. We do not hold AS9100, ITAR registration, security clearance or MOD approval, and we do not print metal. NDAs are available on request. If your project needs any of those approvals, say so at the start so you can rule us in or out quickly.
What to send for a quote
- A STEP or STL file, up to 100 MB each. Without CAD, email a drawing, sketch or photo with quantity and material to order@henleyprint3d.com.
- Quantity and the date you need parts.
- Material or the duty: load, temperature, environment.
- Finish: sanding, painting, coating, threaded inserts or none.
- Critical dimensions marked on a drawing.
- Whether you need an NDA first. Email before sending ITAR or EAR controlled designs.
A complete, clean file avoids delays; see the STEP export checklist for manufacture.
What to ask any 3D printing supplier
Our answers: an engineer reviews every order, process parameters and material lot are recorded per part, and parts are inspected against the drawing before dispatch (see quality control). The full supplier checklist is in how to choose an additive manufacturing supplier, and the quote comparison checklist shows how to compare quotes like for like.
Preparing a file that quotes quickly
- Export STEP for geometry you may change, and STL only for organic shapes.
- Model at real size in millimetres; check units.
- Remove hidden internal solids and duplicate bodies.
- Name the critical faces in a drawing or notes.
- Check wall thickness against the process: thin features fail first.
- Send everything in one email or upload, with the deadline.
A complete model avoids a round of questions, which often saves a day or more of lead time.

Frequently asked questions
What 3D printing services are available in the UK?
Common services are FDM, SLA, SLS and PolyJet printing, plus finishing, design and scanning. HenleyPrint3D offers all of these from Devon.
How do I choose a 3D printing service?
Choose the process from part size and detail, the material from heat, wear and flex, and the supplier from engineering review, inspection records and direct contact.
How fast can a UK 3D printing service deliver?
FDM and SLA start at 1 calendar day and SLS at 2, with finishing, quantity and transit adding time.
Can I order a single prototype or a production run?
Both. Orders range from single prototypes to production runs, and for higher volumes the process, material and inspection plan are agreed before the first build.
What is the best 3D printing service in the UK?
There is no single best. Choose by what you need: process and size for your part, an engineer who reviews the file, inspection against your drawing, and clear lead time. Compare suppliers on the same material, finish, quantity and date.
Is a UK 3D printing service better than an overseas one?
Not always, but a UK supplier can mean faster delivery, no customs and direct conversation with the engineers, which helps when parts need design advice or repeat batches.
Do you offer 3D printing in metal?
No. HenleyPrint3D prints in plastics and resins using FDM, SLA, SLS and PolyJet.
Can I get my design kept confidential?
Yes. NDAs are available on request. Ask before you send files so the NDA is in place first.
