Despite the fact that today's supply chains have become modern marvels of optimal logistics and efficiency, as we've seen with the COVID-19 pandemic, it only takes one link in the chain to disrupt it entirely. 3D printing offers a unique opportunity to solve for this by allowing for greater flexibility and reducing the links in the chain.
I've mentioned a topic like this before in a previous post: 54-3d-printing-localized-manufacturing. I can get rather passionate about it, so I refrain myself from speaking about it too much!
This article does a great job of explaining the benefits of 3D printing in the typical supply chain. Check it out: https://3dprinting.com/news/bolstering-the-stability-of-supply-chains-with-3d-printing/.
