Check out #IJEM's latest animated cover on "Seeing the Invisible: How X-rays Unveil Keyhole and Spatter Dynamics in 3D Printing"! Spatter formation in 3D printing can lead to defects impacting surface quality and fatigue performance of components, while traditional methods often struggle to capture ultra-fast spatter phenomena due to resolution limitations. In IJEM's No. 5 Vol. 6 edition, Prof. Chu Lun Alex Leung, Prof. Peter Lee, and their team demonstrate in situ observation of spatter and keyhole behavior in 3D printing using high-speed synchrotron X-ray imaging. By unveiling the correlation between spatter dynamics and keyhole/depression morphology under industry conditions, they suggest a printing strategy for minimising defects and improving the surface quality of 3D-printed parts.

The latest research in #IJEM shows how tailoring thermal history in additive manufacturing (AM) can unlock customizable material properties without changing alloy compositions or adding post-heat treatments. Using a specially developed Fe–Ni–Ti–Al maraging steel processed by laser-directed energy deposition (LDED), a wide range of strength and ductility was achieved: 💡 Interlayer paused deposition: ~1.54 GPa tensile strength, ~8.1% elongation. 💡 Substrate heating deposition: 1.24 GPa tensile strength, 19.3% elongation. These results surpass the property range of most commercial materials and highlight AM's potential for advanced material performance tuning through strategic process control. 🔓 Let's explore new levels of customization and performance in manufacturing at https://lnkd.in/gd_63Kq7 #AdditiveManufacturing #3DPrinting #AdvancedMaterials #LaserDeposition #Manufacturing #Innovation #MaterialScience #Engineering #Steel #MechanicalProperties #ProcessControl #AMResearch #SmartManufacturing #ExtremeManufacturing

📢 📢 The integration of composite micro-nano structures with diverse characteristics has posed a significant challenge in advanced manufacturing. However, recent research in #IJEM offers a promising solution! Prof. Jianrong Qiu and his team have successfully generated, visualized and manipulated focal volume light fields induced during the ultrafast laser-matter interaction, enabling highly efficient, single-step composite structuring using a single-beam ultrafast laser. What also makes this work stand out is its high universality and applicability across a range of transparent dielectrics. The potential impact? Transformative strides in nanophotonic applications, including encryption, nonlinear diffractive elements, and multi-functional optical modulation!

Please take a look on our most recent article "Fabrication and development of mechanical meta materials via additive manufacturing for biomedical applications: a review" accepted for publication by International Journal of Extreme Manufacturing. This paper provides a comprehensive overview of additive manufacturing (AM) technologies and design possibilities in manufacturing metamaterials for various applications in the biomedical field, of which many are inspired by nature itself. It describes how new AM technologies (e.g., continuous liquid interface production and multiphoton polymerization, etc.) and recent developments in more mature AM technologies (e.g., powder bed fusion, stereolithography, and extrusion-based bioprinting, etc.) lead to more precise, efficient, and personalized biomedical components. Extrusion-based bioprinting is a revolutionary topic creating intricate models with remarkable mechanical compatibility of metamaterials, for instance, stress elimination for tissue engineering and regenerative medicine, negative or zero Poisson’s ratio. By exploiting the designs of porous structures (e.g., truss, triply periodic minimal surface, plant/animal-inspired, and functionally graded lattices, etc.), AM-made bioactive bone implants, artificial tissues, and organs are made for tissue replacement. International Journal of Extreme Manufacturing has an Impact Factor of 16.1 ranked first in the Engineering, Manufacturing category. #3dprinting; #additivemanufacturing; #biomedical; #metamaterials

Synthetic vascular grafts suitable for small-diameter arteries (<6 mm) are in great need. However, there are still no commercially available small-diameter vascular grafts (SDVGs) in clinical practice due to thrombosis and stenosis after in vivo implantation. A new study in #IJEM introduced a high-resolution 3D printing method to create a novel bilayer SDVG with structures and mechanical properties mimicking natural arteries. 📣 📣 The results of the study revealed promising outcomes: One month after implantation, the regenerated arteries had good pulsation and three-layer structures similar to natural arteries, and their compliance (8.9%) was close to that of natural arteries (11.36%). This innovative approach holds promise for the future development of small-diameter vascular grafts, offering new possibilities for patients in need of such interventions. 📖 📖 Learn more: https://lnkd.in/gC2bhfpQ #Manufacturing #ExtremeManufacturing #3DPrinting #VascularSurgery #MedicalDevices #Biomaterials #TissueEngineering #HealthcareInnovation #RegenerativeMedicine #ClinicalResearch #EngineeringSolutions #BiomedicalEngineering #FutureOfHealthcare #3DPrintingInMedicine #PatientCare #HealthcareTechnology #InnovationInMedicine

Design and manufacturing play crucial roles in developing high-end equipment. However, there is often a disconnect between the two, leading to inefficiencies in workflows. In a recent article published in #IJEM, Prof. Dongming Guo from Dalian University of Technology introduces High-Performance Manufacturing (#HPM) as a solution to bridge this gap. The HPM focuses on material-regularized coupling design and innovative approaches to manufacturing inverse problems, ensuring optimal performance at every stage. Prof. Guo also points out that despite its advancements, HPM's theoretical and technical frameworks are still evolving. To fully realize its potential, research should concentrate on practical applications, technical advantages, and innovative methodologies. By integrating design and manufacturing, systematic solutions for process and equipment development can be achieved!

Curious about the recent advancements in designing and manufacturing high-performance micro/nano-robots (#MNRs)? In #IJEM, researchers comprehensively reviewed the material-interface-structure-function/performance coupled design methods and the additive/formative/subtractive composite manufacturing (AFS-CM) methods to design and manufacture high-performance MNRs with multi-materials and complex structures under multi-factor coupling. Looking ahead, they suggest that future MNR development should integrate artificial intelligence (#AI) design, multi-process composite manufacturing equipment, in-situ precision detection tools, and function/performance evaluation systems. "Future design and manufacturing should leverage artificial intelligence to autonomously allocate #materials, #structures, and processes based on functional requirements, while enabling real-time #data transfer with manufacturing equipment to achieve comprehensive information fusion and intelligent optimization throughout the process.” Learn more: https://lnkd.in/gvt3mDSJ #Robots #Manufacturing #ArtificialIntelligence #ExtremeManufacturing #AdditiveManufacturing #Robotics #Design
