Globalization of manufacturing supply chains brings forth opportunities that normally rely on economic, political and climate stability. When stability is challenged, we see massive economic disruptions. At the same time, we observe opportunities leveraged by entrepreneurial thinking. In the 2022 SME Digital Manufacturing Challenge, we want to empower students to envision supply chain opportunities that can be leveraged using digital manufacturing, including additive manufacturing (AM). Such examples span a wide range of domains, technical competencies and sectors; however, your solution must describe how digital manufacturing and AM/3D printing supports a break in the supply chain.
Using a finished product as subject matter, imagine a significant component or subassembly is unavailable due to supply chain disruption. Show how your design team will utilize AM to substitute for the unavailable component or subassembly.
Choose a significant component or subassembly, unavailable due to supply chain disruption. Consider military/medical/agriculture/transportation supply as well.
Redesign the part(s) for AM.
Decide how it will be produced, defining material and process (machine). Show rationale and comparison to the original design and other AM options.
Define how it is equivalent to the original part(s), citing cost concerns and warrantee issues, such as part life and performance. How does the cost of AM compare to the cost of the disruption?
Will it be a permanent or temporary component?
Can the part(s) deviate from the original? If so, what are the impacts of deviations.
Digital Manufacturing includes additive and subtractive processes embracing a considerable variety of materials and processes suitable for creating a wide range of 3D models, prototypes, mock-ups, tooling, end-use parts, assemblies and systems/subsystems. Leveraging digital manufacturing tools while employing Design for Manufacturing (DFM) and Design for Additive Manufacturing (DFAM) enable the optimization of form, fit, and feature/function integration like never before. Therefore, student designers and engineers are challenged to go beyond the classroom or laboratory and showcase their technical and commercial talents by demonstrating new and creative ways digital manufacturing can add value.
Entries are welcome from both college/university students and high school students. The two categories will be judged separately according to the following weighted criteria:
Functionality and durability including health and safety, and quality considerations
– Provide a description and analysis of features and functions 15%
– Justify reason(s) for using AM 10%
Utilization of DDM material(s)
– Justify the material(s) selected 10%
Utilization of DDM process(es)
– Justify the AM process(es) used considering scalability 10%
Design integration and innovation
– Showcase AM capabilities integrated with traditional methods to add value 15%
Digital and physical infrastructure: Systems integration, utilization, value chain leverage, agility, lean and continuous improvement
– Discuss dissemination of designs, manufacturing coordination across and among large corporations and hobbyist makers 20%
Marketing and logistics/distribution
– Justify market appeal, market share forecast, and just in time delivery 10%
Social, environmental, health, safety, and regulatory compliance
– Forecast, explain, and justify the affects anticipated 5%
Judges’ discretion 5%
