3D Printing Patterns, Moulds, Prototypes, Jigs & Fixtures

Henleycraft uses 3D printing as an integral part of the GRP manufacturing process. Our in-house additive manufacturing capability supports pattern making, tooling, jig and fixture production and prototype development, allowing us to move quickly from concept to finished component.



3D Printing Patterns

We use 3D printing to produce patterns for GRP moulding. This is particularly effective for complex shapes, curved surfaces and intricate detail that would be time-consuming to produce by hand. The HMS Warrior anchor shackle is a good example — the shackle pattern was 3D printed, prepared with primer and texture coat to replicate a cast iron finish, and used to produce the GRP mould.

3D Printed Moulds for Composite Parts

For low volume or prototype runs, moulds can be produced directly from 3D printed tooling. This reduces lead time and cost compared to traditional pattern and mould manufacture, making it a practical option for single components or small batches where a full production mould is not yet justified.

Jigs and Fixtures

3D printing allows us to produce bespoke jigs and fixtures in-house. These are used to ensure consistency and accuracy during assembly, trimming and fitting of GRP components.

Prototype and Concept Models

Scaled-down 3D printed models allow customers to review a design before committing to full-size pattern and mould manufacture. The motorcycle seat project is a good example, a scaled model was produced for customer approval before moving to a full-size 3D printed pattern and then production.
