Student Guide (IB Design Technology)

Simple Explanation: Imagine you're designing a chair. Instead of just guessing where to put the material, you can use a computer program that figures out the strongest, lightest way to build it by only putting material where it's absolutely needed. This can lead to cool, unique shapes that are also very efficient.

Why This Matters: This technique allows for the creation of innovative and efficient designs that push the boundaries of what's possible in architecture and product design, often leading to more sustainable outcomes.

Critical Thinking: Consider the ethical implications of using computationally derived forms that may be difficult to interpret or repair using conventional methods.
