Humanity is in crisis and a large part of this is due to the way we manufacture objects, which is wasteful, unelegant and boring. New digital manufacturing methods, especially industrial 3D printing are finally disrupting the stone-age paradigm. We can finally create objects that are as complex, functional and sustainable as nature. But with this shift in production comes a design and engineering challenge: How can we engineer machines that approach the complexity of living things? Lin Kayser explains how he is tackling the problem with his startup, Hyperganic, where he creates parts and entire machines using a combination of algorithms, AI and digital evolution.
