Today, we will explore Additive Micromanufacturing, a fascinating advancement in MEMS fabrication. Can anyone tell me why we might want to use additive methods instead of traditional machining?
Additive methods allow for more complex designs, right?
Exactly! With traditional methods, like bulk micromachining, complexity can be limited. Additive methods let us build up structures. This leads us into our next point - design flexibility. Student_2, can you explain what design flexibility means?
I think it means we can create shapes and structures that can’t be easily made with other techniques?
Right on target! Design flexibility means we can achieve more intricate geometries with less restriction. Excellent. Let’s discuss some specific additive techniques.
