Scientists at The University of Manchester have found that small temperature changes during molten metal deposition can substantially alter the quality of 3D-printed aluminium parts, according to a study published in Materials & Design. The research focused on molten metal deposition, or MMD, a process that deposits pre-melted aluminium rather than melting it in place.

Engineers at the University of Illinois Urbana-Champaign have built the first physical device that can hide objects from heat in any direction, a development with potential uses ranging from protecting sensitive microchips to shielding people and equipment from infrared detection. The device works by guiding heat around an object rather than blocking it. To an infrared camera, the cloaked object appears to simply not exist.

Researchers at EPFL have found that a soft material built for 3D printing also solves one of materials science’s stubborn problems: making elastomers that resist both fracture and fatigue at the same time. The study, published July 13 in Science Advances, shows that double network granular elastomers (DNGEs) achieve fracture toughness values up to 15 times higher than comparable elastomers, and fatigue resistance values up to three times higher. Double network granular elastomers.

University of Utah engineers have built a holographic 3D printer that produces complete shapes in a single exposure rather than building them layer by layer, eliminating the structural seams that weaken conventionally printed parts. The process takes about 20 seconds, compared to the hours required by other laser-based printing methods.

When Vinmec switched on a nationwide robotic surgery network, the real advance was the connective tissue around it: preoperative 3D reconstruction, surgical simulation, and patient-specific manufacturing built into one coordinated system. Vinmec activated its nationwide network of High-Tech Robotic Surgery Centers.

An intelligent optical tracking, high-accuracy, marker-free wireless laser 3D scanner for metrology, reverse engineering, and quality inspection, with no reflective markers and no tethered cables. Optical and laser tracking scanners have long carried two constraints for professional users. Reflective markers have to be applied across a part before scanning, and the operator stays tethered to a wired connection. Revopoint built the Trackit SR to remove both.

Scientists in China have developed a 3D-printed tooth implant that restores the sense of chewing — a capability that conventional dental implants don’t offer — with 90% of trial patients reporting recovered masticatory perception after receiving the device. The implant, developed by researchers at Huazhong University of Science and Technology, uses piezoelectric materials to convert the mechanical forces of chewing into electrical signals, which are then sent to the brain via the tooth nerve.

Nikon SLM Solutions and Bosch Industry Consulting have produced a complete V8 engine block as a single printed part, using the NXG XII 600 laser powder bed fusion system at the Bosch Additive Solution Center in Nuremberg, Germany. The block was printed in AlSi10Mg aluminum, with no casting and no tooling required. Conventional cylinder block production requires tooling that takes weeks or months to develop before a single production part can be made.

Good coffee, a few robot arms, and two days of unusually open talks: inside the symposium bringing robotic large-format 3D printing together. By Robert Dehue · 3DPrinting.com Addidex Connect took place on the working floor of 3D Makers Zone in Haarlem, robot arms and all.

A transformer station in Beverwijk, Netherlands now has an 8-by-5-meter ceramic artwork on its facade, made up of 322 individually designed tiles that were robotically printed at Studio RAP’s workshop in Rotterdam. The client is TenneT, the Dutch grid operator that owns the station. Powerhouse Company designed the building itself; Studio RAP was brought in separately to create the installation.
