Nanoscribe's customer achievements have been listed in the NATURE MATERIALS journal

In recent years, with the development of technology, especially the rapid advancement of aerospace technology, ultra light and ultra hard materials have become a hot topic in the fields of materials science and solid mechanics in the industry. How to achieve excellent properties such as ultra lightweight, high strength, large deformation, impact resistance, and defect insensitivity in materials is a huge challenge in modern material design and manufacturing.

For the challenge of this problem, scientists have chosen a basic structure where the mechanical properties of a tetrahedral structure are dominated by bending behavior. Composite nanodot matrix metamaterials with this structure can absorb a large amount of energy upon impact without being prone to catastrophic fracture.

This year, MIT, Caltech, and ETH Zurich collaborated to address high impact factorsScientific journals Nature MaterialsPublished on“Supersonic impact resilience of nanoarchitected carbon”The research paper.In the paper, the researchers utilizedGermanyNanoscribeThe company's two-photon technology3DPrinting systemPhotonic Professional GTDeveloped a technology that can withstand supersonic particles“Bullet”Mechanical metamaterials of impact. This material, which is thinner than the diameter of a human hair, is composed of carefully designed and processed carbon fiber micro nano dots. If it is mass-produced in industry, it is expected to greatly enhance aircraft, lightweight armor, and protective coatingsAnd the overall performance of other ultra light and ultra hard impact resistant equipment.

Nanoscribe, founded at Karlsruhe University of Technology, known as the "European Massachusetts Institute of Technology", is a manufacturer of high-precision 3D printing equipment for balls. It has been dedicated to promoting research in innovative fields such as mechanical metamaterials, micro/nano robots, microelectromechanical engineering, biomedical engineering, and micro/nano optics, while also providing various optimized process solutions for the university's research community.

After scientists determined the geometric structure of the material, the authors of this article usedNanoscribe two-photon lithography technologyPerform printing. Simply put, two-photon lithography is a high-precision laser 3D printing technology based on nonlinear optical principles. The resolution of ordinary single photon based 3D laser printing technology is easily affected by optical resolution and interlayer displacement mechanical errors, resulting in low accuracy. However, two-photon lithography technology uses high-energy femtosecond laser pulses to cure photosensitive resin in a very small spatial range, thereby improving the printing resolution to an incredible hundred nanometer level accuracy.

After printing is completed, the material is placed in a high-temperature vacuum furnace for pyrolysis, and the resulting polymer is carbonized to produce ultra light carbon nanodot matrix materials.Although carbon materials are usually fragile, the mechanical behavior of the tetrahedral lattice structure designed in the paper is dominated by bending rather than fracture, giving this material * elasticity and impact resistance. This material can bend like rubber when impacted.
