Student Guide (IB Design Technology)

Simple Explanation: Using 3D printing for making special materials (composites) is good because it uses less material, costs less, and makes less trash. We can add things to these materials to make them stronger or even able to break down naturally. It's important to check how well they break down in nature.

Why This Matters: This research is important for design projects because it shows how to make products more sustainably by reducing waste and using materials more efficiently through advanced manufacturing like 3D printing.

Critical Thinking: While 3D printing offers waste reduction, consider the energy consumption of the printing process and the lifecycle of the printing materials themselves. Are there trade-offs between material efficiency and energy usage?

IA-Ready Paragraph: The use of additive manufacturing, as highlighted by Anwajler and Witek‐Krowiak (2023), offers a significant advantage in resource management by minimizing material waste and labor costs. This approach is particularly relevant for the fabrication of multifunctional composites, where precise material deposition can lead to enhanced product performance and reduced environmental impact. Furthermore, the exploration of biomass-derived additives presents opportunities for developing more sustainable materials with potential biodegradability, aligning with principles of circular design.
