FABRICATION
Digital Fabrication Supplier Selection Guide
Select sheet-metal, CNC and rapid-fabrication suppliers using process capability, tolerances, materials, inspection, design feedback, delivery and repeatability.
What to compare
- Supported processes, materials, thicknesses, finishes and secondary operations.
- Tolerance capability and how exceptions are communicated before manufacture.
- Automated or engineering DFM feedback and drawing/GD&T interpretation.
- Inspection, certificates, traceability and first-article options.
- Prototype and repeat-order lead times plus capacity constraints.
- Quoting transparency, shipping, packaging and landed cost.
Questions for shortlisted suppliers
- Which dimensions or features need explicit engineering review?
- What inspection evidence can be supplied?
- How are drawing revisions and repeat orders controlled?
- Which finishing and secondary operations are subcontracted?
- How is a production nonconformance contained and corrected?
