Engineering Prototypes FAQ
What are engineering prototypes?
Engineering prototypes are functional prototype parts manufactured to exacting specifications. They are used for detailed engineering validation, performance testing, and demonstrating technical feasibility. Engineering prototypes typically require tight tolerances, complex geometry, and precision surface finishes.
What tolerance levels can engineering prototypes achieve?
Engineering prototypes are manufactured to tight tolerances. Standard: ±0.05mm. High-precision: ±0.01mm. Ultra-precision: ±0.005mm with CMM inspection. Specify tolerance requirements on your CAD drawing — we advise on achievability.
Can engineering prototypes include complex geometry?
Yes. 5-axis CNC machining enables complex 3D geometry, undercuts, intricate features, and compound curves. Engineering prototypes are designed for complexity — no limits on geometry as long as the design is manufacturable.
How long do engineering prototypes take to manufacture?
Engineering prototypes are manufactured in 3–10 business days from quote approval. Quotes are provided in 2 business days. More complex parts take longer, but the process prioritizes precision over speed.
Do engineering prototypes include CMM inspection?
Yes. Engineering prototypes include CMM (Coordinate Measuring Machine) inspection of critical features to verify tolerances and dimensional accuracy. Material certs and full traceability are provided.
What materials are suitable for engineering prototypes?
Engineering prototypes are manufactured in all engineering materials: aluminium, steel, stainless steel, titanium, brass, copper, and engineering plastics (PEEK, ULTEM). Choose materials that match your production requirements for accurate performance validation.
