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 printing, 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 mobile robots 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.

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.

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.

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.

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.

Engineers have invented a new kind of 3D printer that can print electronic tattoos directly on your skin. Here’s how we’ll use it.

WASP, the Italian manufacturer behind DeltaWASP 3D printers, has unveiled a new construction system which will be used to print sustainable houses in a village.

The Crane WASP, also referred to as the “the infinity 3D printer” is designed to accelerate the development of the technological village of Shamballa, a WASP project to develop 3D printed eco-friendly houses. The company states.

The German start-up company ELiSE creates the DNA of a technical part. Based on the DNA, automated design processes are used to find the best solution which considers all predefined constraints and which is produced by additive manufacturing. Meet ELiSE at ESA’s Start-ups Zone powered by ESA space solutions at IAC 2018.

Many congrats to @Enrico Dini 🔝🍾🎉🎉🎉🥇Enrico reached that outcome after an eclectic professional path: a graduate of Civil Engineering at Pisa University, Enrico has spent his entire career in automation and robotics. In 2004, Enrico envisioned the endless potential of the use of additive manufacturing techniques at architectural scale as a means to affordably reach architectural beauty. Since then, Enrico has dedicated his entire professional career in the pursuit of his passion to 3D print beautiful architecture.

At the Digital Concrete 2018 Conference, several awards will be presented. Award categories include: Best Proceedings Paper, Best Presentation, and Best Poster. Each category will have an award encompassing all entries, and one for students only. The awards will be given at the conference closing on Wednesday, 12 September, before lunch.

In addition, two Pioneering Achievement Awards will be given to two pioneers in the field of digital fabrication with concrete, Prof. Behrokh Khoshnevis and Enrico Dini. Information for the two awardees is seen below.
