3D3DStart a part →Marine 3D printing
Boat parts, built by people who sail offshore.
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. Discontinued fittings recreated to fit.
What we print
If the geometry suits FDM, we can print it.
Autopilot gears and drive levers, winch jaws, spreader boots, hatch hinges, vent cowls, instrument covers, transducer mounts, antenna brackets, rope guide liners and deck fittings. 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.

Materials
Matched to the environment, not the cheapest option.
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. The choice is explained in every quote. Every new fitting earns its place on Mr Jumpa — our 1977 Farr 38 on the Saint John River, sponsored by High End Welding — before it's 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.
