Mechanical parts in industrial machinery and structures that develop thinning or cracks need to be replaced with new ones. In recent years, attempts to repair them have been considered, in order to ...

Penn State and the US Army Research Laboratory (ARL) have introduced LAMAR, a large-format robotic Directed Energy Deposition (DED) platform aimed at faster metal additive research and process control ...

Laser ablation is a process that uses high-energy laser pulses to precisely remove or vaporize materials from a solid surface. When the laser beam focuses on the target material, it absorbs the laser ...

With glass substrates and arc torch, “Collar” hybrid process unites metal shielding gas welding and laser material deposition. Collar Hybrid AM process relies on a combination of arc and laser ...

The major factors affecting the performance of crystalline thin films are the presence of grain boundaries and inherent crystal structure. Post-deposition annealing is frequently employed to improve ...

A new laser-based fabrication method has significantly improved the quality of cesium lead bromide (CsPbBr 3) thin films. Published in Science and Technology of Advanced Materials, the study showcases ...
