Conch may be responsible for preventing head injuries in the future—as well as others—if researchers from MIT have any say. Currently, they are developing and testing 3D printed materials modeled after conch. The super-strong material is extremely resistant to cracking, and in a helmet it would be more protective as there would be comprehensive coverage rather than just a liner. The researchers have just published the results from their study in Advanced Materials. Read more at 3DPrint.com: http://3dprint.com/176277/mit-3d-print-conch-inspired/
