Design for Manufacturability is a product design ideology that focuses on creating a better design at a lower cost by optimising the selection of materials and manufacturing processes. Following these guidelines, the final product should be easier to manufacture and the production should take less time when compared to the original design.

DFM helps us analyse the different aspects of design and manufacturing processes in the light of many prudent principles. It provides new ideas and techniques to bring about a positive change in product design to benefit all the involved parties (designer, manufacturer and customer). Such an advanced manufacturing simulation was once a pipe dream due to the lack of available tools and manufacturing processes. This is no longer the case. Today, with advanced digital manufacturing simulation tools and low-cost fast manufacturing processes, such as additive manufacturing, it is easier to carry out extensive simulations and even create physical iterations
for specific products.

These tools enable deep DFM modeling and real-world testing at a fraction of the original cost. Thus, an increasing number of manufacturers are integrating DFM into their organizations to reap its many benefits.
