+## 3D printing
+I chose to fully 3D print my drone due to it's complex shape and time constraints. I still had a lot of work from university to do. We got encouraged to do compositing but that is super hard with the current design. However it would have been better since it is often lighter and more durable while being a lot more eco friendly. For 3D printing I am planning on using PLA because it has a lower carbon footprint than ABS and it releases less toxic fumes.
