Scientists develop smart technology for synchronized 3D printing of concrete

Posted by in categories: 3D printing, robotics/AI, space

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a technology whereby two robots can work in unison to 3D-print a concrete structure. This method of concurrent 3D printing, known as swarm printing, paves the way for a team of mobile robots to print even bigger structures in the future. Developed by Assistant Professor Pham Quang Cuong and his team at NTU’s Singapore Centre for 3D Printing, this new multi-robot technology is reported in Automation in Construction. The NTU scientist was also behind the Ikea Bot project earlier this year, in which two robots assembled an Ikea chair in about nine minutes.

Using a specially formulated cement mix suitable for 3D , this new development will allow for unique concrete designs currently impossible with conventional casting. Structures can also be produced on demand and in a much shorter period.

Currently, 3D-printing of large concrete structures requires huge printers that are larger in size than the printed objects, which is unfeasible since most construction sites have space constraints. Using multiple that can 3D print in sync means large structures and specially designed facades can be printed anywhere, as long as there is enough space for the robots to move around the work site.

A solid industrial perspective in the Geo-Lunar space

Posted by in categories: 3D printing, habitats, satellites

Some industrial activities can give a ROI in a reasonable times. Recovery and reuse of space debris and wreckages, at least in its recovery part, is very much needed, for orbital safety. With proper orbital infrastructures, to capture debris, the logical next step will be to re-process them, getting powders for 3D printing, a platform for orbital ISRU, very first bricks of orbital factories. Assembly of satellites and vehicles in orbit is a large industrial perspective, that will decrease the cost of design, construction and launch: a first step towards a self sustaining space industrial development. There’s a number of in-orbit operations: transport and maintenance of satellites in orbit, refuelling stations, repair shops, orbital sites, orbital yards, spaceports, habitats. All the activities tied to space tourism, such as hotels and lodging facilities, passengers transportation systems (Earth-Orbit, inter-orbit, Earth-Moon). Products from zero gravity, asteroid and lunar mining are other very promising industrial activities, on which several startups were already born.

Priority to enabling technologies.

Researchers find inspiration in nature to improve ceramic armor

Posted by in categories: 3D printing, cybercrime/malcode, engineering, military

ABERDEEN PROVING GROUND, Md. — Future American Soldiers will be better protected in combat by stronger and lighter body armor thanks to innovative work at the U.S. Army Research Laboratory. Materials science engineers are using nature as the inspiration for breakthroughs in additive manufacturing.

“My project is to design a system that can 3D print armor ceramics that will allow production of parts with graded structures similar to an abalone structure in nature that will improve the ceramic armor’s toughness and survivability with lower weight,” said Joshua Pelz, a materials science and engineering doctoral candidate at the University of California San Diego. He spent this summer working with Army scientists at ARL’s Rodman Materials Science Laboratory at APG to design and build a unique 3D printer.

3D bioPen: A hydrogel injection to regenerate cartilage

Posted by in categories: 3D printing, bioengineering, biotech/medical, neuroscience

Highly specialized cartilage is characteristically avascular and non-neural in composition with low cell numbers in an aliphatic environment. Despite its apparent simplicity, bioengineering regenerative hyaline cartilage in a form effective for implantation remains challenging in musculoskeletal tissue engineering. Existing surgical techniques including autologous chondrocyte implantation (ACI) and matrix-induced autologous chondrocyte implantation (MACI) are considered superior to self-repair induction techniques. However, both MACI and ACI are complex, multistage procedures that require a double operation; first for surgical excision of native cartilage, followed by expansion of adult chondrocytes in vitro prior to implantation by a second operation.

Regenerating robust articular hyaline-like cartilage is a key priority in musculoskeletal tissue engineering to prevent cost-intensive degenerative osteoarthritis that limits the quality of life in global healthcare. Integrating mesenchymal stem cells and 3D printing technologies has shown significant promise in bone tissue engineering– although the key challenge remains in transferring the bench-based technology to the operating room for real-time applications. To tackle this, a team of Australian orthopedic surgeons and bioengineers collaboratively proposed an in situ additive manufacturing technique for effective cartilage regeneration. The handheld engineered extrusion device known as the BioPen offers an advanced, co-axial extrusion strategy to deposit cells embedded in a hydrogel material within a surgical setting.

Canadian Researchers Used 3D Printing to Save a Dachshund Named Patches

Posted by in category: 3D printing

Using a mix of techniques in 3D printing and rapid prototyping, a team of researchers in Canada have successfully replaced about 70 percent of a dachshund name Patches’ skull that had to be removed while excising a tumor. It’s a technique that could some day save human lives as well.

HP’s Metal Jet could be a huge leap for commercial 3D printing

Posted by in category: 3D printing

Just a few years after launching its Multi Jet Fusion 3D printer, HP is ready to get into the world of 3D metal printing with Metal Jet, a new commercial platform. (Did you expect it to be called anything else?) While the consumer buzz around 3D printing seems to be cooling off, it’s still a useful technology for large scale manufacturing — especially when it comes to metallic components. The usual benefits of 3D printing still apply: It can be both significantly faster and cheaper than traditional methods.
