Design for Manufacturing (DFM) is the process of designing parts, components or products for ease of manufacturing with an end goal of making a better product at a lower cost. This is done by simplifying, optimizing and refining the product design.

The 5 Principles are examined during a DFM. They are:

  1. Process
  2. Design
  3. Material
  4. Environment
  5. Compliance / Testing

Ideally, DFM needs to occur early in the design process, well before tooling has begun. In addition, properly-executed DFM needs to include all the stakeholders — engineers, designers, contract manufacturer, mold builder and material supplier. The intent of this “cross-functional” DFM is to challenge the design — to look at the design at all levels: component, sub-system, system, and holistic levels — to ensure the design is optimized and does not have unnecessary cost embedded
