Researchers at Queen’s University Belfast have built a 3D printed flow battery cell that costs around £75 to make, against the £2,000–£3,000 a commercial lab-grade equivalent typically runs, and are giving the design away for free to labs worldwide. Dr…

Small temperature shifts, big quality gains: Manchester maps the defect physics of molten metal deposition
A few degrees at the nozzle can decide whether a 3D printed aluminum part comes out sound or riddled with pores. That is the central finding of a new study from The University of Manchester, published in Materials & Design,…
Italian researchers use field-driven lattice design to cut prosthetic socket weight by 25%
Researchers from four Italian universities have developed a digital workflow for producing patient-specific upper-limb prosthetic sockets with spatially graded lattice structures. Combining 3D scanning, finite element analysis, elastic-plastic homogenization and Field-Driven Design, the method adjusts lattice strut diameter according to…
Purdue’s 3D Printed Groundwater Sensor brings low cost scientific instruments to USGS
Purdue University researchers have built a 3D printed, open-source alternative to the specialized groundwater-flow sensors that the U.S. Geological Survey (USGS) owns in only small numbers, and they can assemble each unit for a few hundred dollars, a fraction of…
EPFL’s 3D Printed Elastomer Resists Both Fracture and Fatigue
A new study in Science Advances finds that a rubbery material first engineered for 3D printing may resolve a problem that has long dogged materials science: producing printable elastomers that are simultaneously tough and durable. Researchers at EPFL’s Soft Materials…
From Chip-Making to 3D: Utah’s Single-Exposure Printing Method
Engineers at the University of Utah have shown off a 3D printing approach that sidesteps one of the format’s persistent weaknesses: the leaky seams left behind when an object is built up slice by slice. Rather than stacking layers, the…
From Laser Control to Microstructure Design in Metal AM
By Michele Pavan, Research Engineering Manager, Materialise A KU Leuven research team has demonstrated something the metal AM industry has been pursuing for years: the ability to locally influence microstructure within a single printed part during the build itself, without…
NSF Backs Automated 3D Printing of Lab-on-a-Chip Devices
George Mason University and North Carolina company Phase Inc. have been awarded a National Science Foundation STTR grant to develop a new class of 3D printed microfluidic devices. The goal is to carry the technology out of the research lab…
SDU Explores Cutting Chemical Use in Metal Recycling for Additive Manufacturing
Associate Professor Mohammad Malekan of the Institute of Mechanical and Electrical Engineering at the University of Southern Denmark (SDU) has secured a Sapere Aude Research Leader grant from Independent Research Fund Denmark to explore whether contaminated metal by-products from industry…
Auburn University and NASA Demonstrate Inkless Electronics Printing in Microgravity
Researchers from Auburn University and NASA Marshall Space Flight Center have demonstrated that conductive metal structures can be printed in microgravity without liquid inks, using a compact, self-contained system that generates, deposits, and sinters metal nanoparticles on demand. The work,…
