Students develop novel multi-metal 3D printing process
Students at ETH Zurich have developed a laser powder bed fusion machine that follows a circular tool path to print round components, which allows the processing of multiple metals at once. The system significantly reduces manufacturing time and opens up new possibilities for aerospace and industry. ETH has filed a patent application for the machine, and the results are published in the CIRP Annals.

'Self-fixturing' friction stir technique removes barriers for US manufacturing
A spinning tool plunges into two pieces of metal, rotating at a high rate of speed. As the tool begins to move, it softens and mixes the metal, creating a powerful weld—one that can securely join similar and dissimilar materials (particularly metals and alloys) without rivets, fasteners, or adhesive. This advanced manufacturing technique—called friction stir welding—requires only a fraction of the energy required by conventional techniques, but it isn't used on many assembly lines today.

Looks like Zelensky is preparing his people for the possible loss of the USA as a direct ally and supplier, at least in the short term. Though I would be very surprised if the USA stopped allowing NATO, EU or other partners to buy US made weapons for Ukraine.
The EU and NATO need to get their heads out of their butts, including Canada, and start working to replace US defense manufacturing capacity.
How about Canada re-tooling those closed US car plants with weapons for Ukraine. I am sure that the workers there would be willing, and proud, to do it!

On design, analysis, and hybrid manufacturing of microstructured blade-like geometries
With the evolution of new manufacturing technologies such as multi-material 3D printing, one can think of new type of objects that consist of considerably less, yet heterogeneous, material, consequently being porous, lighter and cheaper, while having the very same functionality as the original object when manufactured from one single solid material. We aim at questioning five decades of traditional paradigms in geometric CAD and focus at new generation of CAD objects that are not solid, but con…

Simple casting and heat treatment yields alloy with both strength and ductility
In the world of metals, it has long been considered common knowledge that achieving both strength and ductility (the ability to stretch without breaking) at the same time is nearly impossible. When a metal is made stronger, it typically becomes brittle, and when it is made more ductile, it usually loses strength—like a seesaw, where one property increases as the other decreases.

Portable printer developed for fabrication of origami devices
In the present times, origami-inspired three-dimensional (3D) devices are being developed, where a single sheet of material is folded into small devices. These devices are being developed for medical applications like stents or surgical tools; agricultural devices like soil-sensors; and efficient spacecraft radiators or solar arrays that are used in space technology. Along with innovation, it is also important to focus on sustainable technology that can fulfill human needs and is adaptable to e…

Unlocking ceramic 3D printing for next-generation chemical reactors
Scientists at the U.S. Department of Energy's Oak Ridge National Laboratory have integrated binder jet additive manufacturing with an advanced post-processing method to fabricate leak‐tight ceramic components, overcoming a key challenge of ceramic additive manufacturing.

Machine embroidery encodes skin-like tension lines in textiles, enabling mass-customizable wearables
A zigzag stitch enables fabric to stretch until the thread is straight. University of Tartu researchers report in Advanced Materials that thread packing can encode fabric stretchability, leading the way to tailoring wearables at an industrial scale.
