Purdue has recently partnered with VELO3D to 3D print a fuel injector that can replicate hypersonic conditions in their lab. This is a large step forward for hypersonic research and will allow the group to iterate hypersonic designs faster than ever before. Purdue has been leader in hypersonic research space for awhile and recently invested heavily ($18 million dollars to be exact) to establish The University’s Hypersonics Advanced Manufacturing Technology Center (HAMTC) with the help of Lockheed Martin, GE Additive, Dynetics, Aerojet Rocketdyne, GE Edison Works, Boeing and others on the technology to get the facility off the ground. Associate Professor Carson Slabaugh at Purdue’s HAMTC (Image credit: Purdue University) Over the few months since the initial funding, it sounds like the facility has made massive strides. However, they were still hampered by a large issue; testing parts at an above Mach 5 level. They found this region hard to…    read more 

Researchers from Hyderabad in India have successfully transplanted a 3D printed cornea onto a rabbit, which will pave the way for transplants onto human patients. Read on to learn more about this world first. The researchers from Indian Institute of Technology (IIT) ,LV Prasad Eye Institute (LVPEI), and the Center for Cellular and Molecular Biology (CCMB), all located in Hyderabad, produced the cornea using natural, animal-free components. It was printed with a biomimetic ink made from human donor tissue. The researchers decellularized a human cornea tissue matrix and added some stem cells. The old cornea has lived on as the basis of a new cornea and may contribute towards treating scratched/damaged corneas, which can lead to blindness. The cornea in question (Image credit: LVPEI) “It is the first 3D printed human cornea that is optically and physically suitable for transplantation,” read a statement from researchers at LVPEI. “The bio-ink used…    read more 

Researchers from German institutes are planning to send a robotic mobile selective laser melting (SLM) printer to the Moon, to demonstrate in-situ additive manufacturing using lunar regolith as a feedstock. The project is carried out by engineers from the Hannover Laser Center (LZH) and the Berlin Technical University (TU Berlin), and the technology has already been demonstrated successfully on Earth, using simulated lunar conditions. You can see a render of the robot in the image below. Printing with moondust (Image credit: LZH) Moonrise The three-year long “Moonrise” project has received funding from the German Federal Ministry of Economics and Climate Action to the tune of 4.75 million euros ($4.82 million). It is intended to pave the way for technologies for lunar construction by using in-situ resource utilization, in this case, the resource being the silicate regolith of the Moon’s surface. Why utilize local materials? Because sending stuff to the Moon…    read more 

3D printed solid-state battery manufacturer Sakuu has opened up an innovation hub in Silicon Valley aimed at accelerating their battery printing initiatives. The company, who have developed the world’s first solid state battery, intends for the new site to serve as a blueprint for battery printing gigafactories around the world. The new 79,000 square ft facility will house battery, engineering, material science, R&D and 3D printing departments, and will oversee employee training and client product demos. 115 employees are expected to be working at the factory by early 2023, in time for the product rollout later in the year. New Sakuu gigafactory (Image credit: Sakuu) Sakuu has developed two key products that will be showcased at the new factory. The first is the company’s Kavian platform which is the world’s first large scale 3D printing platform for the additive manufacturing of custom ultra-high energy density solid-state batteries for a variety…    read more
