Additive Production for Marine

Parts that shrug off saltwater — where metal corrodes, nylon doesn’t. For the bespoke fitting, the refit one-off, and the composite plug you don’t want to machine. Printed, vapour-smoothed, finished and inspected in-house in the UK, with no tooling and no minimum order.

Overview

It usually starts with one awkward part

A bespoke fitting needs making for a one-off refit. A bracket has corroded again because it was metal in a place metal shouldn’t be. A composite layup needs a plug, and machining it is slow and costly. Different parts, same problem — it is bespoke, low-volume marine hardware in a damp, corrosive, UV-harsh environment. That is the call we take every day.

RYSE 3D is a UK polymer additive manufacturer — FDM, SLS, SLA, MJF — that makes the part, finishes it, inspects it and ships it: one roof, one team you can hold to account. Nylon shrugs off saltwater where metal corrodes — and from a garage in 2017 to a UK factory and two King’s Awards, we make the marine parts that fit, finish and last.

What we run for marine teams

The parts that fit, finish and last

These are the jobs we run for boat builders, yacht yards and marine OEMs every week — bespoke marine hardware on the processes that suit each one. Send us yours and we will spec it the same way.

Ducting & bespoke parts

SLS / MJF · consolidated · finished

Ducting, conduits and bespoke custom parts — consolidated geometry moulding can’t make, finished and ready to fit.

Marine is bespoke, low-volume and brutal on materials — damp, salt, UV and constant load. Nylon shrugs off the corrosion that eats metal, and additive makes the one-offs moulding can’t justify. We will confirm material against your service conditions — UV, load and immersion — so the part lasts. Tell us what is on the bench, and we will tell you the process and the lead time.

What you get

We’re not a print shop — we’re the production line for bespoke marine hardware

Fittings, housings, brackets, ducting and composite tooling. Two people usually sign this off, so here is what each of you walks away with.

For engineers

● Parts that survive saltwater — durable nylon, naturally corrosion-proof, vapour-smoothed for water resistance. Not hobby plastic.
● Tolerances you can sign off — ±0.3 mm up to 100 mm, then ±0.3 mm on the first 100 mm plus ±0.1% for every 100 mm beyond, inspected in-house.
● Bespoke geometry, no tooling — custom fittings and parts moulding can’t justify, made to fit the vessel.
● Composite plugs & tooling — layup plugs and tooling printed instead of machined, faster and lighter.
● A straight answer on process — we tell you what fits, and what doesn’t.

For buyers

● Parts on time, every time — 2.5m+ components in service, fit and finish ready for the build.
● One supplier, not five — print, finishing and inspection under one roof.
● A programme you can defend — PPAP 1–4, ISO 9001, Cyber Essentials, full traceability, NDA-compliant.
● No minimum order — one-offs for a refit or a repeatable run across a build, on the same process.

What we run

Tell us the part. We’ll tell you the process.

Nobody orders “an SLS part”. They order a part that has to do a job and perform. We run all four major processes, so your part goes on the one that performs, not the one machine we happen to own.

Where we fit

When we run your parts, here’s where they land

Additive earns its place when a part is bespoke, the environment corrodes metal, or a refit needs one-offs. For boat and yacht builders, equipment OEMs and refit yards, that is most of the awkward jobs.

●

Fittings & brackets

SLS / MJF PA12. Corrosion-proof fittings, brackets and mounts — durable nylon where metal would rust, finished and made to fit the vessel.

●

Housings & enclosures

MJF / SLS. Electrical and equipment housings, vapour-smoothed for water resistance — sealed against saltwater and finished to fit.

●

Ducting & custom parts

SLS / MJF. Ducting, conduits and bespoke parts — consolidated geometry moulding can’t make, finished and ready to fit.

●

Composite tooling & plugs

FDM / SLA. Layup plugs, patterns and composite tooling printed instead of machined — faster, lighter and easier to revise.

●

Prototypes & patterns

SLA / SLS. Hull models, fit-check prototypes and casting patterns — high detail for design work and low-run parts.

●

Low-volume builds

SLS / MJF. Repeatable bespoke components across a build or refit — no tooling spend, no minimum order.

Right part, right process

Additive isn’t the right answer for every part, and we’ll always tell you so

The value is putting your budget where additive genuinely beats moulding: lower cost at your volumes, real design freedom, and parts in days instead of tooling lead-times. Where that line sits depends on the part — small parts stay ahead to high volumes; bigger or more complex parts suit additive up to around 10,000 a year, after which moulding takes over. For marine work — bespoke fittings, refit one-offs, composite tooling — additive almost always wins, with no minimum order and no tooling.

Where additive wins for you

✓ Metal corroding where it shouldn’t be? Switch to nylon that shrugs off saltwater.
✓ No minimum order — bespoke fittings and one-offs without tooling up.
✓ Vapour-smoothed, water-resistant parts for the damp, salt and UV.
✓ Composite plugs and tooling printed, not machined — faster and lighter.
✓ Consolidated geometry — fewer parts, less weight, designed for the vessel.

Where we’ll tell you straight

● We will confirm material against your service conditions — UV, load and immersion — so the part lasts. Tell us where it goes on the vessel.
● Primary load-path or class-certified hull parts? We are polymer, and those sit outside what we do — we will point you the right way.
● Need a specific certification? We hold ISO 9001, Cyber Essentials and PPAP 1–4 — tell us your standard and we will be straight on what we can meet.
● Not sure where your part lands? Send us the CAD and we will tell you honestly — the right process, the real cost, and where we can save you money. No charge.

FAQ

Marine 3D printing FAQ

Will 3D printed nylon parts survive saltwater?

Nylon does not corrode the way metal does, which is exactly why it suits marine fittings, brackets and mounts that sit in damp, salty air. For added water resistance we vapour smooth parts, which seals the surface and reduces the porosity that would otherwise take on moisture and dirt. We confirm the material against your service conditions — UV exposure, load and immersion — before we print.

Can you make bespoke one-off fittings for a refit?

Yes, and that is where additive is strongest in marine. There is no tooling and no minimum order, so a single custom fitting for one vessel costs what it costs — no mould to amortise. Send the CAD, or send us the part and we will 3D-scan and reverse-engineer it.

Can you print composite layup plugs and tooling?

Yes — layup plugs, patterns and composite tooling printed rather than machined, which is faster, lighter and far easier to revise when the shape changes. We run these on FDM for larger plugs and SLA where fine surface detail leads.

What is the largest marine part you can print?

Up to 500 × 500 × 900 mm in one piece on industrial FDM. Beyond that, larger parts and plugs are printed in sections then bonded and finished in-house, so size is rarely the limiting factor — tell us the dimensions at quote and we will plan the split.

How fast can you turn a marine part around?

Express lead time is 1–3 days on SLS, FDM and SLA, with 5–7 days standard. MJF runs 5–7 working days, standard only — there is no express tier on that process. When a refit is waiting on one bespoke fitting, tell us and we will put it on whichever process makes the date.

Do you work with boat builders and refit yards directly?

Yes — boat and yacht builders, marine equipment OEMs, naval architects, chandlery, refit yards, and both leisure and commercial operators. Work ranges from a single bespoke fitting to repeatable low-volume components across a build.

Can you make hull or load-bearing structural parts?

No. We are a polymer manufacturer, so primary load-path and class-certified hull components sit outside what we do — we will say so and point you the right way. Our marine work is fittings, housings, brackets, ducting, tooling and bespoke hardware.

Which finishes suit marine parts?

Vapour smoothing is the most useful, because it seals the surface against moisture and dirt. Beyond that we offer shot blast polishing, dyeing, vibro polishing and painting up to A-class, plus threaded inserts and bonded fixings so parts bolt to the vessel properly.

How do I get a marine part quoted?

Upload your CAD to our instant quote tool for pricing from a single part up to 100,000, or contact us to talk it through — including sending us a physical part to scan. You can also request material samples to see and feel the finishes before you commit.
