3D-printed foam outperforms standard materials

Lawrence Livermore National Laboratory (LLNL) material scientists have found that 3D-printed foam works better than standard cellular materials in terms of durability and long-term mechanical performance.Foams, also known as cellular solids, are an important class of materials with applications ranging from thermal insulation and shock-absorbing support cushions to…

Tiny tubes move into the fast lane

For the first time, Lawrence Livermore National Laboratory (LLNL) researchers have shown that carbon nanotubes as small as eight-tenths of a nanometer in diameter can transport protons faster than bulk water, by an order of magnitude.The research validates a 200-year old mechanism of proton transport.A nanometer is one billionth of a meter. By comparison, the diameter of a…

Researchers outline physics of metal 3D printing

While the most common method of metal 3D printing is growing exponentially, moving forward from producing prototypes to manufacturing critical parts will be possible only by reaching a fundamental understanding of the complex physics behind the process, according to a new paper authored by Lawrence Livermore National Laboratory (LLNL) researchers. The powder bed fusion…

Researchers 3D-print with reactive materials

Reactive composite materials are everywhere, from the life-saving air bags in your car to the dazzling pyrotechnics in Fourth of July fireworks. But one of the main drawbacks to using these materials has been the unpredictability of their reactions.Historically, the way to alter the performance in reactive materials (i.e. thermites) has been to either change the…

Lawrence Livermore teams up with Autodesk to investigate design of next-generation materials

Researchers from Lawrence Livermore National Laboratory (LLNL) and a Bay Area company are joining forces to explore how design software can accelerate innovation for three-dimensional printing of advanced materials.Under an 18-month Cooperative Research and Development Agreement (CRADA), LLNL will use state-of-the-art software for generative design from San Rafael-based…

Researchers develop efficient method to measure residual stress in 3D printed parts

LIVERMORE, California – Lawrence Livermore National Laboratory researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing.This 3D printing process produces metal parts layer by layer using a high-energy laser beam to fuse metal powder particles. When each layer is complete, the build…

Livermore researchers create engineered energy absorbing material

Materials like solid gels and porous foams are used for padding and cushioning, but each has its own advantages and limitations. Gels are effective as padding but are relatively heavy; gel performance can also be affected by temperature, and possesses a limited range of compression due to a lack of porosity. Foams are lighter and more compressible, but their performance is…
