Digital manufacturing services use electronic design files and order information to communicate manufacturing requirements. Digital file transfer can make collaboration easier, but it does not replace engineering review, revision control or a clear agreement about what the supplier will make.
Control the design source
Identify the part number, drawing revision and model version. State which file controls when a drawing and model differ. Share only approved files and identify who may authorize changes.
Link each file to a quote
Include material, quantity, finish, critical features and acceptance requirements with the request. Ask the supplier to confirm which revision and assumptions the quote covers and to raise open questions before an order is placed.
Keep a record of revisions
When a design changes, record the new version, effective date, affected order and approvals. Confirm whether material, price, inspection or schedule changes before the supplier proceeds.
Plan inspection and handoffs
Specify records that should accompany the part and who reviews them. If outside operations are used, identify who coordinates the work and verifies the handoff.

Keep the digital record usable
Save approved files, quotes, inspection results and changes together under the part number. Before repeat work, confirm that the digital package still matches the current design and order.
