Researchers 3D Print Ceramics Without Time-Consuming and Complex Sintering Phase

In a paper entitled “3D printing dielectric ceramic without a sintering stage,” a group of researchers describes how they created dielectric ceramic parts through 3D printing, while circumventing the usually necessary sintering phase. Conventional sintering is both time- and energy-consuming, they explain. Normally, the ceramic powder is packed with organic additives under compression, followed by... Read More »

Researchers Create Bionic Mushroom with Graphene and 3D Printed Cyanobacteria

Using 3D printing, researchers at Stevens Institute of Technology have created a bionic mushroom. Why? For good reason, actually. The researchers are working to better understand the biological machinery of cells and how they can be used to create new technologies for defense, healthcare and the environment. The mushroom – an ordinary white one from a... Read More »

Researchers Use 3D Printing and Basic Electronic Components to Make Neuroscience More Accessible

While I was worse in math, science was also not one of my strong suits in school. So anything that makes it easier for students to better understand these complex subjects is a good idea, in my humble opinion. Tom Baden, a professor of neuroscience at the University of Sussex, has been collaborating with his... Read More »

Researchers Test Two Configurations of Biowaste 3D Printed Microbial Fuel Cells

Researchers and scientists are constantly working to develop solutions that can save our future world, from solving problems like increasing pollution and climate change to producing clean energy. A group of researchers from the University of Naples Parthenope recently published a paper, titled “Development and Performance analysis of Biowaste based Microbial Fuel Cells fabricated employing Additive...

Scientists 3D Print an Effective Terahertz Waveguide

(a) Segments of the hollow waveguide; (b) experimental results of the loss coefficient; (c) mechanical spliced 90 cm hollow waveguide. The terahertz (THz) wave is the electromagnetic radiation at frequencies from 0.1 to 10 THz, which is located between the millimeter wave and the far infrared wave. It has not been fully studied because of... Read More »

UPenn Researchers Using Jammed Microgels as 3D Bioprinting Inks

Diversity in microgel compositions for ink fabrication. A trio of researchers from the University of Pennsylvania have published a paper, titled “Jammed Microgel Inks for 3D Printing Applications,” on their use of jammed microgels as inks for bioprinting, in order to address the various limitations of 3D bioprinting with hydrogels. Researchers and scientists use 3D bioprinting... Read More »

University of Twente Researchers 3D Print Gold Microstructures Using LIFT Technique

Researchers at the University of Twente have developed a new laser printing technique that allows for the 3D printing of gold nanostructures, including complex overhanging structures. By pointing a very short laser pulse onto a nanometer-thin metal film, a tiny droplet of liquid metal is ejected onto the substrate, where it solidifies. The technique is called... Read More »

Researchers Use Aerosol Jet 3D Printing to Develop Neuronal Interface with More Anti-Inflammatory Ability

a) Schematic illustration of the mechanism for formation of nanogel-based membrane based on the self-assembly of OPC-incorporated amphiphilic polydimethylsiloxane-modified N, O-carboxylic chitosan (OPMSC), followed by hydrogel-bonding interaction of OPC. The TEM images display the network structure of b) PMSC and c) OPMSC spherical nanogels. 3D printing has been used in the past to help treat... Read More »

3D Printed PLA and PCL Composite Biodegradable Stents Show Promise

PCL (white) and PLA (black) stents Biodegradable stents have shown great potential in reducing complications in patients, but they require further study, according to the authors of a paper entitled “3D-Printed PCL/PLA Composite Stents: Towards a New Solution to Cardiovascular Problems.” The researchers outline five main requirements that a biodegradable stent must meet: Their manufacturing...

3D Printed Graphene Aerogel May Lead to Powerful Supercapacitors

Supercapacitors are energy storage devices that charge very rapidly and can retain their storage capacity through tens of thousands of charge cycles. Their applications include regenerative braking systems in electric vehicles. They hold less energy in the same amount of space as batteries, and they don’t hold a charge for quite as long – but...
