Design for Manufacturability (DFM) and Design For ease of Assembly (DFA) are often combined into one all-encompassing technique called Design for Manufacturability & Assembly (DFMA). Both are terms used to describe the practice of improving a products design in such a way that it improves the manufacturability or ease of assembly.
Design for Manufacturability (DFM) is the practice of designing a product in such a way that it is easy to manufacture.
When designing a product, it is important to understand how the product will be manufactured as certain manufacturing methods have limitations on what kinds of shapes, details, sizes or materials can be used.
Below is a list of some of the common manufacturing methods used today to manufacture most of the products we see around us.
Design for Assembly (DFA) is the practice of designing a product in such a way that it is easy to assemble. There are a number of guidelines used during the design process that will make the assembly of the product easier, faster, cheaper, and safer.
