Need for selection criteria
Can functions or sub-parts be merged into one component?
Can the number of interfaces and/or joints be minimised? Can the product be reduced in size or volume while achieving the same function?
Can the assembly time be reduced?
Typical candidates are:
- single-function assemblies split in several parts due to manufacturing constraints;
- complex assemblies made of single-function parts, each manufactured separately to reduce design and fabrication complexity.
How many design variations are expected?
Can this product be separated/assembled in core and customisable add-ons?
How much variation between design versions?
What are typical batch sizes?
The standard parts are mass produced conventionally whereas the customized parts are manufactured in small lot sizes.
Typical candidates tend to be consumer products found at human/surroundings interfaces.
Weight and materials costs savings
Can weight-reduction improve performance of the components?
Can material volume be reduced to save money at equal or superior performance?
Can topology be optimised?
Typical candidates are complex load bearing parts found in mobile and dynamic applications.
How could the product operate more efficiently? How can losses be reduced during operation? How can performance be improved during operation?
How can mass or energy transport be maximised?
How can energy conversion be improved?
How can component servicing be made easier?
How can life expectancy of product be improved?
Can running costs be lowered?
Success requirements for AM-specific designs
- lowering manufacturing costs (simplifying the assembly, limiting investment in specific expensive tools)
- adding benefits during product operation (lower operating costs, higher productivity, unique performance)
- offering value for performance to customers
- What are typical batch sizes?
