A few days ago, researchers at Lawrence Livermore National Laboratory (LLNL) and Autodesk signed an agreement to study how to use design software to accelerate innovation in advanced materials for 3D printing .
The 18-month Collaborative Research and Development Agreement (CRADA) means that LLNL's research team will use Autodesk's generation design software to study the microstructure of materials.
The project will leverage key technologies such as additive manufacturing , material modeling and architectural design, and organize materials at the micro and nano levels through computational design.
This project, jointly developed by LLNL and Autodesk, will examine how to improve design performance by studying the process of a new generation of protective helmets as a test paradigm. Researchers say the helmet research project was chosen because the helmet represents a type of object that requires lightweight construction, absorbs shocks, and can predictably dissipate energy. They said that using this project to research advanced additive manufacturing technology is ideal.
LLNL and Autodesk's research team will create a composite micro-mechanism that can consume energy more efficiently than current helmet liners that are supported by foam or backing.
“As an organization dedicated to driving the limits of generative design and high performance computing, Autodesk is our ideal partner for the next generation of manufacturing,†said Anantha Krishnan, deputy director of engineering at LLNL.
Mark Davis, senior director of design research at Autodesk, said that research on the helmet design process will help to reinforce a multi-objective design problem.
“We conclude by comparing the various design methods in history that many of the previously restrictive manufacturing constraints can be eliminated,†said Eric Duoss, LLNL co-chief researcher and materials engineer. “Additive manufacturing offers the opportunity to We have achieved unprecedented breakthroughs in the wide application of new structures and new material properties."
Currently, researchers have to design which type of helmet has not yet been finalized. Duoss believes that helmets used in rugby, baseball, cycling and skiing are all possible targets.
“One important thing is that we hope to understand what a great helmet design looks like through this collaborative R&D agreement and to manufacture and test the designed helmet parts,†he said.
In recent years, LLNL's additive manufacturing project team has used 3D printing technology to create new ultra-light and super-strong mechanical materials, mechanical energy absorbing materials and graphene aerogels.
About this project, LLNL team members include computing engineers Nathan Barton, Mark Messner and Todd Weisgraber; chemical engineer Tom Wilson; materials engineer Tim Ford; chemist Jeremy Lenhardt; applied physicist Willy Moss; and mechanical engineer Michael King .
