Design for Manufacturability (DFM)

Design for Manufacture is an approach during design aimed at reducing the cost of manufacture and making this process easier to complete.

DFM aspects include:

• Making molded parts easy to remove from molds.
• Use a larger radius on angles to ease material flow.
• Reduce the need for machining.
• Reduce the need for multiple operations.
• Using standard parts wherever possible.
• Using single materials rather than composites.
• Do not over-specify tolerances.
• Dimension from a single datum to reduce tolerance errors.
