Marine 3D printing

The fitting the chandlery stopped stocking.

Autopilot gears, winch jaws, spreader boots, rope guide liners: FDM-printed in ASA or PETG-CF from a photo and a measurement, shipped from New Brunswick.

Marine 3D printing

Marine 3D printing fills the gap when the chandlery stopped stocking the part. FDM in ASA or PETG-CF reproduces discontinued fittings from a phone photo and a tape measure, quoted within 24 hours. Autohelm drive lever $65, Lewmar winch jaw $95, spreader boot $35. Printed in New Brunswick, shipped across Canada.

Masthead systems

The junction box, remade.

A masthead junction box printed in ASA-GF with heated threaded inserts and a gasket seat — a discontinued fitting rebuilt to take salt, sun, and vibration at the top of the rig.

Rigging

Deadeyes, printed in batch.

Three-hole rigging blocks reproduced from a single sample — matched hole spacing and a consistent load path, done in one print run instead of a six-week special order.

Discontinued fittings

The fitting nobody stocks anymore.

Interior light bezels the chandlery quietly dropped — rebuilt in FORMA from a photo and a measurement, so a working fixture never gets scrapped over one cracked ring.

Rope range

Deck hardware that takes the load.

Cleats, winch jaws, line guides, and rope-range fittings in carbon-reinforced PETG-CF — stiff under sheet load and matched to the original when the maker moved on.

From the crew

Built by people who sail offshore.

Every part earns its place on the water before it reaches a customer. That's a new Olympic-class mainsail we helped bend on the night before the centenary Fastnet.

How a job runs

How does a marine parts order actually work?

  1. 01

    Send a photo and a dimension

    A phone photo of the broken or missing fitting and one key measurement. If the part is completely gone, describe where it lived on the boat. That is enough to start a quote.

  2. 02

    Fixed quote in 24 hours

    A fixed price, the material matched to the environment, and a ship date. The quote explains the material choice in plain language — no jargon, no upsell.

  3. 03

    FDM-printed in marine-grade material

    Geometry is built in FORMA, our own CAD engine, from your exact dimensions. Printed by FDM in ASA, PETG-CF, or TPU as the job demands.

  4. 04

    Shipped from New Brunswick

    Parts ship across Canada within days of approval. For the right project — a refit, a race prep, a breakdown — the printer and the people travel to the boat.

Marine materials

Which material survives salt, sun, and rope work?

Material is matched to the environment the part lives in — not to the cheapest option. The choice is explained in every quote.

MaterialBest for on a boat
ASAUV and salt exposure — spreader boots, deck fittings, rope guide liners, vent cowls
PETG-CFStiffness and load — winch jaws, cleats, brackets, autopilot levers, hatch mechanisms
TPUFlexible seals, gaskets, and rope guide inserts

Process is always FDM — Fused Deposition Modelling — in our New Brunswick shop. Never resin, never SLA. ASA and PETG-CF handle the majority of marine work. TPU is specified where the job demands flex or sealing.

Proof

Where are parts tested before they reach your boat?

On Mr Jumpa — our 1977 Farr 38 on the Saint John River, sponsored by High End Welding — before they are offered to anyone else.

Straight answers

What marine parts can you 3D print?
Any FDM-printable fitting: autopilot gears and drive levers, winch jaws, spreader boots, hatch hinges, vent cowls, instrument covers, transducer mounts, antenna brackets, rope guide liners and rope range deck fittings. If the geometry suits FDM and the environment suits ASA, PETG-CF, or TPU, we can print it.
Can you build a part without drawings or a CAD file?
Yes. A phone photo of the broken part and one key measurement are enough to start. We rebuild the geometry in FORMA, our own CAD engine, and return a fixed quote within 24 hours.
Do FDM-printed parts actually hold up offshore?
ASA and PETG-CF are engineering plastics, not hobby filament. ASA is UV-stable and salt-resistant for deck fittings and spreader boots. PETG-CF is stiff under load for winch hardware. Every new fitting earns its place on Mr Jumpa — our 1977 Farr 38 — before we offer it to other boats.
How long does a part take to arrive?
Quoting takes 24 hours or less from your first message. Once you approve, most parts ship from New Brunswick within three to five business days. Emergency turnarounds are possible — ask when you send the photo.
Is this only for sailboats?
No. We print for workboats, RIBs, outboard tenders, and powerboats. The material choices shift based on the environment; the approach is the same. Send a photo of whatever is broken or discontinued.
How does marine fit into what 3D3D does overall?
Marine is one of several verticals we serve — alongside software, web design, private AI, and field services. The 3D printing capability is the same across all of them. Marine is where we have the deepest offshore experience and the most tested parts.
