Frequently Asked Questions

What is the difference between CNC machining and 3D printing?

CNC machining is subtractive — material is removed from a block to create the part. It offers high precision and strength, ideal for metals and mechanical parts. 3D printing is additive — layers are built up. It’s faster for complex shapes and low quantities, especially in plastics.

How fast can I get a prototype?

Most prototypes are delivered in 3–10 days depending on complexity and technology (CNC, SLA, SLS). We offer 24-hour online quoting to get you started fast.

Do you support small batch production?

Yes! We specialize in low-volume production from 1 to 1,000+ pieces using injection molding, CNC, or casting. No MOQ required.

What materials can you work with?

We support a wide range: metals (aluminum, steel, brass), engineering plastics (ABS, PC, PEEK, Nylon), silicones, and polyurethanes. Material selection depends on your application and volume.

Are you certified for automotive or medical projects?

Yes. We are TS16949 certified and PPAP compliant, serving automotive clients like Audi, Porsche, and VW. We also support medical device manufacturing with cleanroom capabilities and documentation.
