Design for Additive Manufacturing: Implications for Sustainability

Speaker: Dr. David W. Rosen
Professor Emeritus, Georgia Institute of Technology, College of Engineering, George W. Woodruff School of Mechanical Engineering

Short biography:
David W. Rosen David Rosen is a Principal Research Scientist at the Institute for High Performance Computing and the Singapore Institute for Manufacturing Technology, both A*STAR institutes in Singapore. He was a Professor in the School of Mechanical Engineering at the Georgia Institute of Technology for many years. Additionally, he held faculty and research positions at the Singapore University of Technology & Design. He received his Ph.D. at the University of Massachusetts in mechanical engineering. His research interests include computer-aided design, additive manufacturing (AM), and design methodology, with a specific interest in design for additive manufacturing. He is a Fellow of ASME. Also, he is the recipient of the 2013 Solid Freeform Fabrication Symposium, International Freeform and Additive Manufacturing Excellence (FAME) Award and is a co-author of a leading textbook on AM. In the standards community, he chairs the ASTM F42 subcommittee on design for additive manufacturing and was awarded the ASTM Award of Merit and promoted to Fellow of ASTM.

Additive manufacturing (AM) is a key digital manufacturing technology leading to Industry 4.0 processes. Its digital input enables great flexibility and adaptability to changing markets, lot-size-of-1 and mass customization, and little if any lead-time since no hard tooling is needed. Its shape complexity capabilities enable part consolidation where several (or many) conventionally manufactured parts can be combined into one part with complex geometry. These characteristics can have major benefits for life-cycle costs and sustainability impacts of products containing AM parts. However, the AM processes themselves are not necessarily more efficient or environmentally friendly than conventional manufacturing (CM) processes. This talk explores opportunities for radically redesigning parts and products to take advantage of the unique capabilities of AM. After a consideration of the sustainability characteristics of AM processes, an analysis is offered of implications for product design. Results of life-cycle analyses (LCA) are highly dependent on the system extent being analyzed. Some alternative system extents are proposed to illustrate their effects. A design strategy is proposed for incorporating sustainability considerations into products and AM processes. Examples are used to illustrate the application of the design strategy. Throughout the talk, the emphasis is on exploring research issues rather than providing quantitative results.


Towards the Prevention of Rebound Effects by Design

Speaker: Dr. Daniela C. A. Pigosso
Associate Professor, Technical University of Denmark, Department of Civil and Mechanical Engineering, Design for Sustainability

Short biography:
Daniela C. A. Pigosso Daniela Pigosso is Associate Professor on Sustainable Design at the Technical University of Denmark (DTU) and a member of DTU’s Centre for Absolute Sustainability. She is the Principal Investigator of an ERC Consolidator project (REBOUNDLESS) which aims to prevent the occurrence of rebound effects by design, and co-leads the ready2LOOP project, which aims to enhance readiness of manufacturing value chains for the Circular Economy. Her research and innovation activities are demonstrated in 20+ national and international projects, carried out in close collaboration with industry, governmental and non-governmental organisations. Currently, Daniela serves as a Member of the Advisory Board of the Design Society and at the ASAP Service Management Forum. In addition to several high-impact publications and scientific contributions, Daniela has had an impressive industrial and societal impact throughout her career.

Never before has there been a stronger global focus on the development of sustainable solutions, but society’s most well-intended efforts to solve sustainability challenges have not yet achieved the expected positive sustainability benefits due to rebound effects. Rebound effects are negative unintended consequences of interventions that arise due to induced changes in system behaviour, which undermine ca. 40% of the potential sustainability gains of sustainable solutions. Despite the increased recognition that rebound effects are defined and can be addressed by design, there is still limited employment of design as a powerful leverage point at which to intervene in production and consumption systems. In this keynote presentation, Daniela will discuss the need for the further advancement of design science towards the design of reboundless solutions (i.e., products, product/service-systems and socio-technical systems that are resilient to rebound effects). In addition to enabling addressing societal needs within the planetary boundaries, the development of reboundless solutions will enable the transition to a new sustainable design paradigm targeted at the systemic level, enabling the design of sustainable production and consumption systems that are resilient to rebound effects.


AI in Product Development: A Perspective View

Speaker: Jon Hirschtick
Chief Evangelist at PTC, Cofounder of SolidWorks and Onshape

Short biography:
Jon Hirschtick A technology pioneer and leading entrepreneur in the computer-aided design (CAD) industry, Jon Hirschtick has spent his career building software products that companies use every day to design their hardware products. Founder and former CEO of several successful companies, including Onshape (acquired by PTC) and SolidWorks (acquired by Dassault Systems), Jon is now Chief Evangelist at PTC, where he helps usher in the next generation of major advancements in product design. When he is not working on CAD and PDM tools, Hirschtick entertains customers and peers with stories from his days on the famed MIT Blackjack team, featured in the movie "21" and the History Channel's "Breaking Vegas”. Hirschtick holds bachelor's and master's degrees from MIT, where he majored in mechanical engineering.

The recent fast advancements of Artificial Intelligence (AI) in many domains makes us all naturally curious abouts the potential for AI in product design. The current state of AI usage in product design tools is relatively limited. But it’s coming: product designers should be excited about what lies ahead. In this talk, Jon Hirschtick will delve into an overall view of AI in product development. Where is it being used already? What are some of the exciting research projects happening in AI and product design? What is the full range of potential applications? And, for those of us who build tools for product development, what are the things we need to be considering in this new world of AI?
