Student Guide (IB Design Technology)
Simple Explanation: 3D printing lets you make really complex shapes that use less plastic or metal and create less trash compared to old ways of making things.
Why This Matters: Understanding how to design for 3D printing helps you create products that are not only innovative but also better for the environment by using fewer resources.
Critical Thinking: While AM offers waste reduction benefits, consider the energy consumption and material sourcing implications of the printing process itself. How do these balance out the material waste savings?
IA-Ready Paragraph: This research highlights how additive manufacturing (AM) offers significant advantages in resource management by enabling the design of complex geometries that minimize material waste. By leveraging AM's flexibility, designers can create optimized structures, reduce the need for support materials, and consolidate parts, leading to more sustainable product development.
