The two methodologies that frame the work of Design for Manufacture and Assembly (DFMA) focus on design for ease of manufacturing and ease of assembly (Boothroyd & Dewhurst, 2011). For example, where traditional manufacturing limitations would require a complex assembly, AM could allow for a single, pre-assembled build [13,14]. design-for-assembly (DFA): Design process focused on ease of assembly, fewer parts, parts that are easier to grasp, move, orient and insert them with end goal of low-cost assembly. Lesson 1 James Dyson Foundation A cyclical assembly is an assembly that repeats the same cycle each time the assembly is completed.
