What is Design for Manufacturing or DFM?

October 25, 2016 by Jennifer Catalan

Design for Manufacturing (DFM) is the method of design for ease of manufacturing of the assortment of parts that will form the product after assembly. DFM is primarily concerned with reducing overall part production cost and minimizing the complexity of manufacturing operations.


Design for Manufacturing is the process of designing or engineering a product so that it is easy to manufacture at the lowest possible price. The process should include review of the raw material selection, secondary processes (finishing, plating), dimensional requirements and even final packaging. It’s the technical version of the “What if” and “Why did you choose…” game!

Two great Design for Manufacturing questions: What needs to be added? What needs to be removed?

Design for Manufacturing Aims to:

  1. Reduce material, overhead and labor cost
  2. Shorten the product development cycle
  3. Focus on standards to reduce cost

Key Principles in the DFM Process:

  • Minimize part count
  • Standardize parts and materials
  • Create modular assemblies
  • Design for efficient joining
  • Minimize re-orientation of parts during assembly and/or machining
  • Simplify and reduce the number of manufacturing operations
  • Specify ‘acceptable’ surface finishes for functionality
