Study Notes
Sustainability In Additive Manufacturing
- A design refinement procedure is needed to modify product designs due to coarse or irregular boundaries
- Material is eliminated in the design refinement procedure where the relative density is below the threshold
- Energy and material consumption analysis
- Life cycle inventory/Life cycle impact analysis compilation
- LCIA provides information related to the environmental significance of natural resource use and environmental releases
- Use the advantages of RM processes
- Do not build the same parts designed for conventional manufacturing processes
- Do not consider traditional mechanical design principles
- Reduce the number of parts in assembly by intelligent integration of functions
- The four stages of the product life cycle
- Product and process design
- Material input processing
- Make-to-order component and product manufacturing
- Closing the loop
- CT scans are quicker and cheaper compared to MRI and ultrasonography scans
- CT scans are less affected by motion artifacts compared to MRI scans
- CT scans are time-consuming and expensive for routine clinical use
- Operators are exposed to higher radiation with CT scans
- There is a risk of ionizing radiation and iodinated contrast agents with CT scans
- Porosity and defect analysis can be done
- Surface roughness or topography of an AM part can be analysed
- X-ray computed tomography provided advancements in industrial design
- Limitations of visual testing can be improved
- The scope and utilities of Radiographic testing can be increased
- Ultrasonographic testing has been revolutionary in the field of metal additive manufacturing
- The domain of eddy current testing can be broadened
- Constraints of on-surface testing can be removed in penetrant testing
- The costs of thermographic testing can be brought down
- Acoustic testing is difficult to use due to extreme sensitivity requirements
- Trials of testing in magnetic testing can be reduced
Sustainable Impact Evaluation
- Material and energy savings in production of high value products
- Improved product functionality and efficiency in use
- Lower energy intensity and waste avoidance in the manufacturing process
Challenges
- Educating manufacturers about possible uses and benefits of AM
- Implementation of distributed maintenance system
- Certification of new components
- Capturing and replicating learning in future applications
- Limited and uncertain performance due to AM technology's low maturity
- Requirement for standards and regulations
Material Input Processing
- Process reactants are non-toxic and can be recycled locally
- Localised material recycling
- Input recycled materials are from larger-scale recycling systems, potentially more efficient than local recycling systems
- Diversion of by-product from waste stream
- Material and process standardization
- Process scale-up for new materials
- Possibility of material contamination
- Limited material options
- Limited recyclability of product at its end-of-life due to mixed materials
Manufacturing
- Increased access to digital designs for spare parts
- More localized manufacturing
- Less high value waste generated
- Raised awareness of manufacturing process and its impacts
- Improved access to equipment
- Increased equipment utilization
- More localized production through proximity of producer to customer
Challenges At Manufacturing Stage
- Limited availability of digital designs
- Cost of acquiring new digital designs
- Limited functionality and utility
- Reliability and quality of 3D printing process
- Encourages materialistic society and consumerism
- Services are currently fragmented and unevenly distributed
- Majority of services are lower-end consumer 3D printers
End-of-Life Strategies
- Small and simple equipment, quick and easy to use as mobile or small-scale recycling station
- In-situ recycling of common waste from everyday products and packaging
- Improved product utilization
- Reduced material consumption
- Designed for longevity
- Automated processes, all process steps integrated into one
- Remanufacturing and repair of high value components at low cost
Challenges
- Limits on recyclability of material due to quality loss
- Educating consumers about recycling 3D printed material
- Replication of business model to other sectors
- Limited integration of AM with other techniques in design and production
- Required mindset shift for designers and engineers
