Renishaw, a leading engineering technology company, has partnered with Cookson Industrial, a UK-based specialist in precious metal additive manufacturing (AM), to reduce the costs associated with 3D printing platinum-rhodium. This collaboration leverages Renishaw’s RenAM 500S Flex AM system, enabling Cookson Industrial to produce high-temperature corrosion-resistant components with improved material efficiency. The advancement is particularly significant for industries such as glass fibre manufacturing, where the viability of using platinum rhodium in additive manufacturing has been enhanced. Cookson Industrial, a division of Cooksongold and a subsidiary of HM Precious Metals, brings over three decades of expertise in designing and producing precious metal alloys. Faced with platinum rhodium prices averaging £80,000 per kilo, minimizing material waste was essential to make production economically feasible. To address this challenge, Cookson Industrial selected Renishaw’s RenAM 500S Flex, a laser powder bed fusion system designed for research and development in additive manufacturing.

Researchers from Ritsumeikan University and the University of Science and Technology Beijing, have developed an advanced edge-highlighting method aimed at enhancing the clarity of visualized 3D scanned objects. Led by Professor Satoshi Tanaka and involving key team members Ms. Yuri Yamada, Dr. Satoshi Takatori, and Prof. Liang Li, the group’s innovative approach addresses common visualization issues by separately emphasizing sharp and soft edges in complex point cloud data, overcoming limitations seen in traditional methods. Published in Remote Sensing, these findings promise clearer representations of intricate 3D objects, particularly useful for preserving and studying cultural artifacts. Explaining the research’s broader significance, Prof. Tanaka notes, “Our 3D edge extraction approach is not merely an improvement but rather an extended technique that captures areas not covered by traditional methods. For archaeologists and historians, this tool opens new possibilities for specialized visual analysis of cultural heritage objects. For the general public, it offers a… read more
A recent study from Queen’s University Belfast has employed 3D printing to create cacao-based formulations infused with raw Greek honey and vitamin D3 (VitD3). The researchers aimed to improve supplement delivery by addressing taste and bioavailability issues. Their approach involved blending organic cacao with varying concentrations of honey and introducing VitD3, using specialized 3D printing technology to form precise, stable “printlets.” Three honey types—Vitex Honey, Lavender Honey, and Jerusalem Sage Honey—were each melted at 37 °C and incorporated into 100% organic cacao liquor. The team prepared two concentrations, 5% and 10% (w/w), to identify how varying honey ratios affected the resulting mixtures. Physicochemical tests indicated that the chocolate-honey formulations stayed liquid-like under ambient conditions and remained stable up to around 38 °C. Rheological analyses revealed that adding honey increased viscosity, enhancing the structural stability of the 3D printed shapes. Graphical abstract. Image via Science Direct. Lavender Honey at 10% concentration emerged as… read more
Oak Ridge National Laboratory (ORNL) has successfully tested a 3D printed specimen capsule in its High Flux Isotope Reactor. The capsule, known in the industry as a rabbit capsule, was designed and manufactured using a laser powder bed printer with stainless steel materials. This marks the first time an additively manufactured component of this type has been qualified for reactor use. Image Credit: Oak Ridge National Laboratory The specimen capsule underwent nearly a month of testing inside the High Flux Isotope Reactor, where it demonstrated its ability to withstand the reactor’s high neutron flux environment. These capsules play an essential role in nuclear fuels and materials research by containing experiments during irradiation testing. “This is a significant step toward demonstrating that additive manufacturing can be used to develop and qualify specialized components that cannot be conventionally machined,” said Richard Howard, group lead for irradiation engineering at ORNL. The technology offers… read more
