Our SLA platform

Printed on the Formlabs Form 4L in open mode

Every SLA part we ship is printed on the Formlabs Form 4L, washed on the Form Wash L and post-cured on the Form Cure L — print, wash, cure and finish all in-house. Wash time, cure and hand finishing are what take a part from as-printed to show-ready, and we control all three under one roof rather than sending work out.

We run the Form 4L in open mode, so we are not restricted to a single supplier’s resin range and can choose the right resin for your part rather than the one the machine came with. Build envelope is 353 × 196 × 350 mm.

The basics

What is SLA 3D printing?

Stereolithography (SLA) is a resin 3D printing (resin printing) process that laser-cures liquid photopolymer layer by micro-layer. Because the layers are so fine, SLA gives the smoothest surface and finest detail of any 3D printing process — isotropic, true to CAD, with no layer lines to sand and no fibre texture. That makes SLA the high-resolution route for rapid prototyping and for parts where surface and detail decide whether a part works: a master for casting, a crisp housing, a clear lens, a pattern that has to read perfectly — at large-format size.

How does SLA 3D printing work?

  1. Slice. Your CAD is sliced into micro-layers, with the resin chosen for the detail, stiffness, clarity or flame rating the part needs.
  2. Laser-cure. A laser cures the resin one micro-layer at a time, building fine features and text down to fractions of a millimetre.
  3. Support & build. Supports hold overhangs during the build on the large-format platform, then come off in finishing.
  4. Wash & cure. Parts are washed and post-cured to full properties.
  5. Finish. Cured, cleaned, sanded, primed and painted — clear parts polished to optical clarity.
  6. Inspect. Dimensional inspection before the parts ship, ready to present.

Comparison

SLA vs FDM & machining

When a part lives or dies on surface and detail. SLA gives a smooth, detailed, show-ready surface straight off the printer, so there are no FDM layer lines to sand for hours and no visible texture on show surfaces — and masters, patterns and tooling come in days, not the weeks a machined master or a cast pattern takes.

FDM still wins for big, load-bearing parts in engineering nylons, and machining wins where you need metal. For appearance, detail, clarity, ESD and flame-rated parts, SLA is the smoothest, truest-to-CAD route. Not sure which fits? Send the CAD and we’ll point you to SLA, FDM or SLS. No sales call, no obligation.

✗

The usual way

Sand and fill FDM layer lines for hours. Live with visible texture on show surfaces. Machine a master from billet. Wait weeks for a cast pattern.

✓

With RYSE 3D

Smooth, detailed surface straight off the printer. Features and text down to fractions of a millimetre. Isotropic parts, true to your CAD. Masters, patterns and tooling in days.

FAQ

SLA 3D printing FAQ

What is SLA 3D printing?
SLA (stereolithography) laser-cures liquid resin layer by micro-layer to produce the smoothest surface and finest detail of any 3D printing process, isotropic and true to CAD, with no layer lines to sand and no fibre texture. It is the go-to for appearance models, masters, patterns, clear and ESD-safe parts.
What is the largest part you can SLA 3D print?
Our large-format SLA envelope is 353 x 196 x 350 mm, big enough for full-size housings, masters and casting patterns in a single piece.
Which SLA resins do you offer?
Six engineering and specialty resins: high-temp ceramic-filled, black PU cast-like, UL94 V0 flame-retardant, ESD static-dissipative, optically clear, and flexible Shore 80A. Tell us the job and we will spec the resin free with your quote.
Can you 3D print clear or transparent parts?
Yes. Our optically clear resin is polishable for transparent parts, lenses, light-pipes and flow visualisation, finished in-house to a smooth show surface.
Do you offer ESD-safe and flame-retardant 3D printing?
Yes. We run a static-dissipative (static dissipative) ESD resin for electronics jigs, trays and housings, and a UL94 V0 flame-retardant (flame retardant) resin for enclosures and parts that need a flame rating.
How much does SLA 3D printing cost in the UK?
SLA pricing depends on part size, resin, finish and lead time. Upload a STEP or STL to our instant quote tool for GBP pricing, with no tooling and no minimum order, from a single prototype to low-volume batches.
What is the difference between SLA and FDM or SLS 3D printing?
SLA laser-cures resin for the smoothest surface and finest detail, ideal for masters, patterns, clear and appearance parts. FDM prints big, load-path parts in engineering nylons; SLS fuses nylon powder for functional parts with no supports. Send the CAD and we will tell you which fits.
Where can I find a resin or SLA 3D printing service near me in the UK?
RYSE 3D is a UK 3D printing service — a resin 3D printing service and SLA 3D printing service based in Shipston-on-Stour, Warwickshire. We’re central for the Midlands, Coventry, Birmingham, Oxford, London and the South East, and ship SLA resin parts UK-wide on next-day carriage. So whether you’re searching for an SLA 3D printing service near me, a resin 3D print service, SLA 3D print UK, or simply a 3D print near me, upload your CAD from anywhere in the UK and we’ll print, finish and ship to you — no local bureau needed.
Do you offer next-day and rapid SLA 3D printing?
Yes. Next day and express SLA turnaround is available on many parts, alongside standard lead times. Rapid resin 3D printing with instant online pricing, all cured, finished and inspected at our own UK facility.
What finishing is available for SLA parts?
Parts are cured, cleaned, sanded, primed and painted in-house, ready to present. Clear parts are polished for optical clarity. Printed, finished and inspected under one roof.
Can SLA be used for casting patterns and tooling?
Yes. SLA is ideal for masters and casting patterns, and for jigs, fixtures, tooling and moulds, thanks to fine detail and a smooth surface straight off the printer, with ceramic-filled resin for stiff, heat-resistant tooling.
Is SLA good for high-resolution, high-detail parts?
Yes — SLA is the highest-resolution process we run. It laser-cures resin in micro-layers for high-detail parts with fine features and text down to fractions of a millimetre and the smoothest surface of any 3D printing process, isotropic and true to CAD. It’s the go-to for rapid prototyping, appearance models and anything where detail decides the part.
Can SLA produce masters and patterns for investment casting?
Yes. SLA masters and casting patterns are widely used in foundry and investment casting workflows — the smooth surface and fine detail transfer cleanly, and we can print them in days rather than the weeks a machined or cast pattern takes.
Can you do batch and low-volume production with SLA?
Yes. Beyond one-off prototyping, SLA suits batch production and low-volume production of appearance models, ESD tooling, clear parts and flame-retardant enclosures, with unit price falling as quantity rises and part history held on your account for repeat orders.
Do you offer trade accounts for 3D printing?
Yes. Regular buyers get a trade account with a dedicated account manager, part history held on the account so repeat batches do not need re-quoting, and volume pricing that scales.
Where can I download SLA resin datasheets?
Our SLA capabilities brochure carries the full property tables for all six resins, the build envelope and finishing options. Request a copy and we’ll send it over.
