Motiva ltd promotes energy and material efficiency in Finland. The recently published a report to aid small and medium enterprises (SME) to improve their material efficiency.The report includes a breadth of methods and examples of best practices for SMEs, such as industrial symbiosis, material efficiency audits in production sites and DfE guidelines.
Ruoyu Song received a student travel award to the Solid Freeform Fabrication symposium being held in Austin, TX in August 2016. The awards are funded by the National Science Foundation and were selected based upon candidates’ essays on the broader challenges facing additive manufacturing in their research areas, and how their work relates to and addresses these challenges.
Ruoyu’s work addresses the sustainability issues that may arise from mass-deployment of 3D printing technologies. Her work evaluates and reduces the uncertainty of environmental impacts of additive manufacturing and reveals new insights regarding design for sustainable usage behavior for fused deposition modeling in particular. The work is expected to advance usage context modeling for engineering systems in general.
This paper is a revised and updated version of Dr. Telenko’s previous work. The original publication is utilized in university classrooms around the world. The updated work is improved given feedback and formatted to aid utilization for design and education. It is available through the ASME Journal of Mechanical Design website or by request.
A Compilation of Design for Environment Guidelines
Telenko C, O’Rourke JM, Conner Seepersad C, Webber ME. A Compilation of Design for Environment Guidelines. ASME. J. Mech. Des. 2016;138(3):031102-031102-11. doi:10.1115/1.4032095.
Policymakers, consumers, and industry leaders are increasingly concerned about the environmental impacts of modern products. In response, product designers seek simple and effective methods for lowering the environmental footprints of their concepts. Design for environment (DfE) is a field of product design methodology that includes tools, methods, and principles to help designers reduce environmental impact. The most powerful and well-known tool for DfE is life cycle assessment (LCA). LCA requires a fully specified design, however, which makes it applicable primarily at the end of the design process. Because the decisions with the greatest environmental impact are made during early design stages when data for a comprehensive LCA are not yet available, it is important to develop DfE tools that can be implemented in the early conceptual and embodiment design stages. Based on a broad critical review of DfE literature and best practices, a set of 76 DfE guidelines are compiled and reconciled for use in early stage design of products with minimal environmental impact. Select guidelines are illustrated through examples, and several strategies for using the guidelines are introduced.

Abstract: Design and other fundamental topics in engineering are often isolated to dedicated courses. An opportunity exists to foster a culture of engineering design and multidisciplinary problem solving throughout the curriculum. Designettes, charettelike design challenges, are rapid and creative learning tools that enable educators to integrate design learning in a single class, across courses, across terms, and across disciplines. When two or more courses join together in a designette, a multidisciplinary learning activity occurs; multiple subjects are integrated and applied to open-ended problems and grand challenges. This practice helps foster a culture of design, and enables the introduction of multidisciplinary design challenges. Studies at the Singapore University of Technology and Design (SUTD) demonstrate learning of engineering subject matter in a bio-inspired robotics designette (MechAnimal), an interactive musical circuit designette, and an automated milk delivery (AutoMilk) designette. Each challenge combines problem clarification, concept generation, and prototyping with subject content such as circuits, biology, thermodynamics, differential equations, or software with controls. From pre- and postsurveys of students, designettes are found to increase students’ understanding of engineering concepts. From 321 third-semester students, designettes were found to increase students’ perceptions of their ability to solve multidisciplinary problems.
