Wow, this one developed into a great topic. I find extrusion a very promising technology in many aspects and believe that it will find more and more usage in the future. Many lightweight, functional and strong products are being produced. Especially the usage in automotive is a gamechanger. Many aluminium car chassis have large amounts of extrusions. Than there are Lotus cars that are made of large sections of extrusions
. There are very nice examples posted on this topic, thanks to every contributer.
Does anybody know how fine/detailed a small extrusion can be? How complex can it be?
