This article forms part of 3D printing metamaterials. Researchers are currently trying to find out ways to modify microscopic properties by printing micro-objects.
Lawrence Livermore National Laboratory created a new plan to explore all these possibilities. Using a projection micrography technique (PSL), a plan can hold 10,000 times its own weight. Like most metamaterials we looked at in this series, this power is based on the structure’s geometry.
The LLNL team employed a system to project UV light from the LED onto a micromirror. After reflecting the light through a series ocular elements, it reduced the size of its beam and projected it to photopolymerization. Researchers tested different lattice shapes and found that they have a bearing on the stability and strength.
Polymer resin is their main material. But the research team also has the capability to build metal and ceramic microlattices using ceramic materials and metal added to gum. This creates a more sturdy object while remaining lightweight.
LLNL developed this technology based off of the results. LLNL employs this technology in order to examine how metamaterials, 3D printing and other technologies can help optimize helmet design. 3D printed thin layers of 3D foam were used to compare traditional elastomer elastomers with 3D printed metamaterials. While the elastomers are slower, 3D printed materials age better than 3D printed ones. Studies have also been done on copper-polymer mixtures which shrink when heated.
Cheng Zhu, an Lawrence Livermore National Laboratory researcher, and Wen Chen who was previously a postdoctoral fellow, developed ink from silver and gold particle inks. After the printing process, 3D parts are heated to condense silver particles and create a gold-silver alloy. For porous, gold-colored parts, the 3D parts go into a chemical bath.
Yet, these nanoscale systems could be made more efficient. Max Planck Institute of Light Sciences, Germany has invented a method that could be called a prelude or precursor to atomic printing. This technology couples light and a single electron or nanoparticle within a parabolic reflection to create light wave clipping.
In this way, both the spacetime distribution of light and either the polarization or oscillation directions of the electrical field can be focused onto the object on a smaller scale then the wavelength. It has been proven that this laser beam can trap an atom and create nanostructures.
This powder can be used to create nano-and microscale 3D printed objects, although most of it is being applied later at the macroscopic scale. Scientists are currently working in teams to make these small-scale objects that can then be deployed outdoors. Virginia Tech is studying the effect of seven order of magnitude magnified on structured materials. Researchers at Virginia Tech have created metal parts tens or centimeters wide made from nanoscale hollow tubes. These tube-shaped components are more elastic than other similar products, and their strength is up to 400%.
LLNL’s own commitment to combining nanoscale and stereolithography has led to large-area projection microscopic Stereolithography. This will increase the size of nanoimprinting. Bryan Moran is the creator of LAPSL. Each tile has many details. Together they make a movie. “This tool allows you to make large parts faster, which is very useful.
