Usually,designers start with a concept or some general idea of what a product will look like.That isn't the case for the researchers at Lawrence Livermore.Instead,they are using Autodesk's Project Dreamcatcher software,which allows designers to input specific design objectives,including functional requirements,material type and so on,to serve up a design based on what the researchers need it to accomplish."In some ways this is a completely new way of thinking about design,"technical researcher Eric Duoss said.The idea involves taking the same elements that make up strong,flexible structures and making them smaller. Imagine the Eiffel Tower's lattice (design,but very small. The lab is currently testing a variety of materials to build its helmet constructed of nano-sized lattice.One of the more promising elements is 3-D printed silicon(),which could be used to replace the current foam pads that most helmets for sports use.Internal analysis has shown these silicon pads could absorb 50%more energy than a solid piece of foam.It was previously impossible to construct these formations,but an increase in 3-D printer resolution has started the design innovation. The 3-D printed microarchitecture technology is mostly being researched at the university level.The scientists at Lawrence Livermore are patenting various discoveries made along the way.The lab is also considering this same technology for other applications, like bicycle helmets."Beyond helmets,there are a lot of opportunities for 3-D printed microstructural design
