How Design-for-Assembly Helps Additive Manufacturing Succeed

(Read the full article. It discusses the issue in detail.)
For engineers and industries that embrace product simplification and part consolidation strategies, AM is a dream process—a breakthrough in the production economics and advanced design functionality that many have pursued for decades.
The main creativity issues in AM as essentially the same ones as in traditional product development: how to think about the efficiency of the whole, including system-wide engineering and inclusionary functionality around fewer, more complex geometries and across parts and related assemblies.
AM can benefit significantly, if we know how to drive all design facets and puzzle pieces toward simplicity and can see the purpose of the product as a whole, executed in as few parts, operations and suppliers as possible.
Economics of Part Number Reduction
Part number reduction provides direct benefits to inventory storing, planning and control, factory throughput (easy or no assembly required), quality (often improved when part interfaces are eliminated), reduction of overhead (part administration, bill of materials, ERP and more), and more rapid and improved supply chains with less number of suppliers. The financial impact of product simplification on downstream processes is well-documented. Now that AM technologies are producing end products at even lower costs, designers have to consider the capabilities of AM to design more complex parts that give part count reduction. It’s time to drive design and manufacturing toward AM-type advantages/benchmarks in cost, speed, performance and supply chain efficiency.
Research, experimentation and full-scale industry implementation have shown again and again that producibility guidelines and automation cannot match the surprising productivity gained from simplification of the product via reduction of the number of separate parts and their operations.
Nice Post.
