Functional prototypes
Test fit, assembly, handling and basic real-world use before committing to a more expensive manufacturing route.
Prototyping
Make, test, change, repeat.
Fast physical iterations for fit, handling and presentation.
Appearance models
Check scale, proportions and presentation. Refined FDM settings can be used when visual quality matters more than speed.
Iteration support
If a test identifies a change, CAD support can be added for straightforward geometry updates and design-for-print improvements.
Small pilot batches
Once a prototype works, repeat it in a short run without jumping immediately to tooling or high-volume production.
