Every hardware startup eventually hears the sentence: "We can build this, but not as drawn." That sentence means redesign, new tooling, new boards and lost months. DFM exists to make sure you never hear it.

The short answer
DFM — Design for Manufacturing — means designing a product so it can be built repeatably, at target cost and quality, with real factory processes. To Be Named Labs applies DFM from the first sketch, because most of a product's manufacturing cost gets locked in during design, long before anyone talks to a factory.

Large companies have manufacturing engineers in the room from day one. Startups usually don't. They design for the prototype — whatever a 3D printer or a hand-soldered board can produce — then discover that production processes have different rules.
Late changes get expensive fast:
| When you find the problem | What it costs to fix |
|---|---|
| During concept | A sketch revision |
| During CAD and layout | Hours to days of design work |
| After prototypes | New prototype batch, weeks of delay |
| After tooling | Tool modification or new tool, often weeks and lakhs |
| After launch | Recalls, returns, reputation |
DFM moves discovery to the cheap rows of that table.
The circuit can be perfect and still fail at the assembly line.
Enclosures and mechanical parts follow the rules of their process — injection moulding, sheet metal, machining, die casting.
DFA, DFM's close cousin, asks how people or machines put the product together.
Every unit needs testing at the end of the line. Design for it.
DFM doesn't mean bureaucracy. It means asking the right questions at the right moment.
Our hydroponics system lives in a humid, wet environment and gets serviced by venue staff, not technicians. That shaped DFM decisions from the start: sealing, material choice, serviceable modules, connectors that can't go in wrong. None of that is decoration. It's how the product survives contact with real use.
DFM decisions depend on how many units you'll build.
| Volume | Typical enclosure process | DFM focus |
|---|---|---|
| 1–50 | 3D printing, CNC | Speed, iteration |
| 50–500 | Vacuum casting, soft or aluminium tooling, sheet metal | Bridge to production geometry |
| 500+ | Steel injection moulding | Full moulding rules, cycle time, part count |
Design your prototype with the production process in mind even if you print it. Then the jump to tooling becomes a step, not a redesign.
Design for Manufacturing — designing products so they can be produced reliably and economically with real manufacturing processes.
DFM focuses on whether each part can be made efficiently. DFA focuses on how easily those parts can be assembled into the product.
At the concept stage. Most manufacturing cost is decided by early design choices, so DFM thinking should start before the first prototype.
Slightly, upfront. It usually saves far more by avoiding tooling changes, board respins and production delays.
