No minimum—we handle 1-piece prototypes to 10,000+ mass production. First prototypes get 15% off; small batches (under 50) include a nominal processing fee (waived for 3+ repeat orders).

Prototypes (1-5 pieces): 3-5 days
Small batches (5-100): 7-10 days
Mass production (100+): 15-20 days

Yes—every order includes traceable docs: raw material mill reports, 3D printing parameters, and post-processing test data (linked to each part’s serial number).
