What it is
DFM (design for manufacture) is the practice of adjusting a product’s design so it can be made reliably, repeatedly, and at sensible cost with a chosen process. It covers geometry, materials, tolerances, finishes, and assembly.
How to use DFM feedback
Treat DFM comments as cost and risk signals, not as optional nitpicking. Ask which changes are required for the process versus which are cost optimisations you can defer.
The cheapest DFM changes happen before tooling or bulk material buys.
