Design for manufacturing, maintenance, repair and disposal4 objectives
- Manufacture, repair, maintenance and disposal.
- Students should be aware of, and able to explain, the need to modify designs to make them more efficient to manufacture, including: • reducing the number of manufacturing processes • how the choice of materials affects the use, care and disposal of products: • labelling of materials to aid separation for recycling • making products easy to disassemble or separate • application of the six Rs of sustainability: • reduce the quantity of materials, of toxic materials, of damaging materials and associated energy use • reuse components and parts • rethink by using eco friendly alternative materials • recycle materials and/or components into new products • maintenance: • temporary and integral fixings • use of standardised parts • allowing for service and repair/ replacement of parts • ability to upgrade with software downloads.
- Students should be aware of, and able to explain, the different ways in which a product can be designed to allow for more efficient manufacture, including: • ribs and webbing to reduce material thicknesses • snap fittings to remove the need for fixings/adhesives • internal moulded screw posts for use with self tapping screws • use of pre made components • use of standardised patterns and sizes • addition of texture in moulding to reduce number of manufacturing processes • self finishing. Disassembly.
- Students should be aware of, and able to explain, how a product can be designed and manufactured with disassembly in mind, including integral fixings and active disassembly using smart materials such as SMA and biodegradable parts.

Exam tips
- Read questions carefully: Take your time to understand what each question is asking before answering.
- Focus on material properties: When discussing materials, always relate their properties to their impact on manufacturing and disposal.
Common mistakes
- Ignoring user feedback in design: Incorporate user testing and feedback at various stages of the design process to ensure the product is user-friendly and effective.
- Confusing the six Rs: Memorize the six Rs and understand their definitions to avoid confusion.
