Rapid Sheet Metal Prototyping
Validate your designs with physical models before mass production.
Precision engineering, versatile materials, and seamless transition to manufacturing.
Why Choose Sheet Metal Prototyping?
A prototype is more than just a model; it's a critical tool for risk reduction. It allows designers to assess functionality, fit, and aesthetics in the real world. Unlike plastic 3D printing, sheet metal prototypes offer a seamless transition to the final product, using the actual materials intended for mass production.
- Attract Investors: Showcase durability and finish quality.
- Test Functionality: Validate structural integrity under real loads.
- Scale Efficiently: Smoother move from prototype to mass production.

Fabrication Processes & Scalability
Laser Cutting
Highly efficient for intricate designs. Uses a focused laser beam to cut precise shapes with minimal waste.
Scale to Production: 1-15 DaysCNC Punching
Computer-controlled press ideal for repetitive patterns, holes, and complex geometries with high consistency.
Scale to Production: 1-15 DaysBending
Using press brakes to achieve precise angles and specific dimensions. Crucial for structural components.
Scale to Production: 1-15 DaysStamping
Includes punching, blanking, drawing, and embossing using dies. Best for high repeatability.
Scale to Production: 1-15 DaysWelding
Joining metal pieces using heat/pressure for strong, durable connections in complex assemblies.
Scale to Production: 1-15 DaysAssembly & Kitting
Final assembly of components and kitting for organized manufacturing or distribution.
Scale to Production: 1-15 DaysDesigning for Manufacturability
Optimize your designs for rapid prototyping to ensure cost-efficiency and structural integrity. Following these best practices streamlines the process.
Need design advice? Contact EngineersConstant Thickness
Maintain uniform material thickness. While welding multiple sheets is possible, it adds cost. Ensure designs fall within standard gauge ranges.
Universal Tooling
Design parts to use standard tool configurations. If a part is too complex, consider splitting it into pieces to be riveted or welded.
Generous Tolerances
Sheet metal tolerances are looser than machining. Factor in material thickness and production steps when defining constraints.
Brake Limitations
Press brakes cannot create closed geometry. Ensure your design allows for tool access during the bending process.
Material Options
