Scientists at the Department of Energy Manufacturing Demonstration Facility at Oak Ridge National Laboratory have their eyes on the prize: the Transformational Challenge Reactor, or TCR, a microreactor built using 3D printing and other new approaches that will be up and running by 2023. But their en...

The construction industry is currently facing two major challenges: the demand for sustainable infrastructure and the need to repair deteriorating buildings, bridges, and roads. While concrete is the material of choice for many construction projects, it has a large carbon footprint, resulting in hig...

Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living ...

The process of building landing pads, habitats, and roads on the Moon will likely look different than the common construction site on Earth. Excavation robots, for one, will need to be lightweight yet capable of digging in reduced gravity. A large-scale construction system could be autonomous and eq...

Scientists have created synthetic soft surfaces with tongue-like textures for the first time using 3D printing, opening new possibilities for testing oral processing properties of food, nutritional technologies, pharmaceutics, and dry mouth therapies. UK scientists led by the University of Leeds in ...

As part of the Artemis program, NASA is returning astronauts to the Moon where we will prepare for human exploration of Mars. Additive manufacturing, or 3D printing, experts from NASA, industry, and academia are pioneering methods to print the rocket parts that could power those journeys. NASA’s Rap...

Forget glue, screws, heat or other traditional bonding methods. A Cornell-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed. This form of technology, known as “cold spray,” results in mechanicall...

Design is the first demonstration of a magnetic, multi-material pump 3D printed all in one piece. A new miniature pump — compact, valveless, and operated magnetically — demonstrates the broad capabilities of devices manufactured by 3D printing. Measuring only 1 centimeter in volume, the pump was fab...

These spur gears – seen in the image above with a euro cent coin for scale – have been produced in stainless steel to a space standard of quality using nothing more than an off-the-shelf desktop 3D printer. ESA-supported startup TIWARI Scientific Instruments in Germany has developed a technique allo...

Food engineers in Brazil and France developed gels based on modified starch for use as “ink” to make foods and novel materials by additive manufacturing. It is already possible to produce food with a 3D printer, potentially delivering products that suit consumer preferences regarding tas...

A team at UMD has created a shape-changing 3D printing nozzle that controls fiber orientation during printing, enabling advanced 4D printing with just one material.  Engineers at the University of Maryland (UMD) have created a new shape-changing or “morphing” 3D printing nozzle that...

Singapore researchers develop new method for ‘printing’ fresh vegetables, leading to tastier, more nutritious food for patients with swallowing difficulties. Researchers from Nanyang Technological University, Singapore (NTU Singapore), Singapore University of Technology and Design (SUTD)...

3D-bioprinting method enables advanced tissue fabrication by using a yield-stress support bath that holds bioinks in place until they are cured and works with a wide array of bioinks. Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and fun...

An X-ray telescope designed to search for supermassive black holes could be built using a novel 3D-printing technique called plasma metal deposition. The ESA space telescope – which would also be used to map hot gas structures and determine their physical properties – is due to be launched in 2033. ...

Professor Nicholas Fang’s startup Boston Micro Fabrication uses a novel light-focusing method to make ultraprecise printers. Whether it’s computer chips, smartphone components, or camera parts, the hardware in many products is constantly getting smaller. The trend is pushing companies to come up wit...

Imaging technique could enable new pathways for reducing concrete’s hefty carbon footprint, as well as for 3-D printing of concrete. The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scienti...

Focus on the reaction environment, not just the catalysts, offering a path to scalable, climate-relevant solutions. Lawrence Livermore National Laboratory (LLNL) scientists and their collaborators are leveraging the power of 3D printing to improve the performance of electrochemical reactors used to ...

JDRF funds creation of implant to automatically regulate blood glucose levels. Rice University bioengineers are using 3D printing and smart biomaterials to create an insulin-producing implant for Type 1 diabetics. The three-year project is a partnership between the laboratories of Omid Veiseh and Jo...

LLNL scientists improved metal 3D printing by replacing traditional Gaussian laser beams with Bessel beams, which distribute heat more evenly and reduce defects like porosity.  While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design...

Lawrence Livermore National Laboratory (LLNL) scientists have developed a new method for 3D printing living microbes in controlled patterns, expanding the potential for using engineered bacteria to recover rare-earth metals, clean wastewater, detect uranium, and more. Through a novel technique that ...

A new machine-learning system costs less, generates less waste, and can be more innovative than manual discovery methods. The growing popularity of 3D printing for manufacturing all sorts of items, from customized medical devices to affordable homes, has created more demand for new 3D printing mater...
