3D-Printed Brain Tissue a Success

A 3D-printed layered structure that incorporates neural cells to mimic the structure of brain tissue has been created by researchers at the ARC Centre of Excellence for Electromaterials Science (ACES) in Australia, and it could have major consequences in studying and treating conditions such as schizophrenia and Alzheimer’s. The three-dimensional structure will allow scientists to better understand the complex nature of the brain and its 86 billion nerve cells. We look at the benefits and risks of this scientific breakthrough on the Lip News with Jose Marcelino Ortiz and Jo Ankier.

New Hyproline System Capable of High-Speed Mass Customization of Metal 3D Printed Parts

At the end of last year, Davide Sher predicted that 2016 would see metal 3D printing move from a technology capable of producing small batches to a fully-automated method for serial manufacturing. Davide cited a number of machines in development that herald the age of serial metal 3D printing, but he may have left one system out: the Hyproline platform.

TNO Hyproline PrintValley metal 3D printer

The Hyproline is the result of an EU additive manufacturing initiative began in 2012 to create a high-performance production line for small series metal parts. After several years, the group of industry partners involved, including researcher organization TNO and Swedish metal printer manufacturer Höganäs, have finalized the Hyproline system. The machine uses a similar platform as TNO’s PrintValley, which involves a conveyor belt mechanism to pass multiple build plates beneath a print head. The result is an automated assembly line that can produce a variety of custom parts at high speed.

A practical solution to mass-producing low-cost nanoparticles

USC researchers have created an automated method of manufacturing nanoparticles that may transform the process from an expensive, painstaking, batch-by-batch process by a technician in a chemistry lab, mixing up a batch of chemicals by hand in traditional lab flasks and beakers.

Consider, for example, gold nanoparticles. Their ability to slip through the cell’s membrane makes them ideal delivery devices for medications to healthy cells, or fatal doses of radiation to cancer cells. But the price of gold nanoparticles at $80,000 per gram, compared to about $50 for pure raw gold goes.
