MarineLab3D turns marine spare parts into parametric, on-demand 3D prints
The marketplace's initial catalogue of about 50 designs lets boat owners set thread size, diameter, and length before a model generates a print-ready STL
MarineLab3D, a new English-language marketplace developed in Italy, sells 3D printable marine parts as parametric designs rather than fixed STL files. A buyer sets dimensions such as diameter, thread size, and length, and in some listings, a name to be embossed directly in the browser; the platform then generates a JSCAD-based model on demand and runs a watertight check on the mesh before releasing the download, according to the company.
The storefront lists 52 products at the time of review, split across categories including engine and propulsion (17 designs), interior and cabin (22), plumbing and pumps (18), deck and rigging (16), and tools (14), with 15 of the total offered free. Materials span FDM plastics such as ASA, PETG, carbon-fiber-reinforced nylon, and TPU, as well as SLA and SLS resins and, for select parts, CNC-machined steel or aluminum.
Boat-specific spare parts
Boat hardware wears out in a market with little standardized supply: fittings, caps, and mounts are often specific to a hull or a discontinued product run, leaving owners with no manufacturer to call. MarineLab3D pitches its parametric approach as a way to bridge that gap with one design per part type rather than one file per boat, an approach the company describes as addressing a structural limitation of static marine file libraries.
The catalog includes threaded BSP fittings, through-hull components, tank caps, and device mounts mapped to specific hardware brands, including Garmin, B&G, Raymarine, Simrad, DeWalt, Makita, and Milwaukee. The company says each listing carries print guidance and explicit notes on which parts are not suitable for structural or safety-critical use.
Open to marine designers
Of the 52 listed designs, MarineLab3D publishes 49 under its house account and three under outside creator Gian Luca Pistoni. According to the platform’s public terms, outside creators set their prices with a €4.99 (about $5.69) minimum, retain ownership of their intellectual property, and earn a 50 percent or 70 percent revenue share, depending on the chosen license model.
MarineLab3D reviews submissions for print quality before publishing. Individual parametric designs on the marketplace are priced mostly between €4.99 and €9.50 (roughly $5.69 to $10.83), with free listings available in most categories. The company says creators who submit fixed, single-configuration STL files can have them converted into parametric models for the marketplace, and that listings carry no exclusivity requirement.
