Functional 3D printed prototypes: a practical guide for SMEs
Goals, materials, tolerances, testing and transition to short production runs.
From CAD to a real-world test
A functional prototype verifies assembly, clearances, ergonomics and behaviour before production. Clear goals and acceptance criteria make every iteration measurable.
Material, orientation and tolerances
Technology, material and orientation affect strength and accuracy. Critical dimensions, fits and operating conditions must guide part selection and inspection.
Test, correct, repeat
Documented assembly, measurement and testing turn the first print into useful data. The updated model becomes a reliable basis for pilot runs, spares or short production.
