The Vienna University of Technology and the Medical University of Vienna have jointly developed the world's first 3D printed "brain model." Using advanced two-photon polymerization (2PP) technology, these models are able to accurately reproduce the brain's microstructure, including nerve cell networ Read More

Since the 21st century, with the rapid development of high-speed trains and aerospace technology, high-strength aluminum alloy components have gradually developed in the direction of large-scale, integration and complexity. The traditional aluminum alloy preparation method has some problems, such as long processing cycle, high cost and easy defects. As a kind of additive manufacturing process, laser melting deposition technology has the advantages of short preparation period, low cost and high forming quality, and has become one of the important means for the preparation of high-strength aluminum alloy components. The traditional laser melting deposition technology uses laser beam to form a molten pool on the surface of the matrix, and the powder enters the molten pool and is heated to melt. However, in the process of ultra-high speed laser melting deposition, the powder melts above the molten pool under laser heating, and only a small amount of powder melts in the molten poo Read More

In April 2024, the 120-year-old car brand Renault (RNO) teamed up with the French Alternative Energy and Atomic Energy Commission (CEA) to develop a new type of 3D printing material. The goal of the collaboration is to create components with adaptive mechanical behavior and enhanced performance, whi Read More

Neural stem cells (NSCs) transplantation can reconstruct some neural circuits and functions, which is a promising treatment for spinal cord injury (SCI). However, the survival rate of NSCs directly transplanted to the lesion site is low, and the differentiation is easy to get out of control. 3D biop Read More

On April 28, 2024, according to Russia's Tomsk State University (TSU), cosmonaut Oleg Artemyev submitted more than a dozen leaf samples to the school. The samples were created on board the International Space Station (ISS) using Russia's first space 3D printer. TSU scientists were involved in the development of the printers and carried out mechanical tests on them. Read More
