3D printing company Micronics announced the launch of its new Micron desktop selective laser sintering (SLS) 3D printer.The company stated that Micron is priced at $2999 and aims to bring industrial grade 3D printing capabilities to desktops for professionals and hobbyists. One of the main features of Micron is its ability to print complex objects without the need for supporting structures. This i...
Recently, high-performance laser supplier Skylark Lasers announced that it has raised $5 million in investment to further advance its efforts in miniaturized laser technology.Skylark Lasers is established at the center of the Scottish Photonics Cluster, focusing on the design and production of compact diode pumped solid-state (C-DPSS) lasers with the purest spectral characteristics, providing high...
Researchers from the University of Witwatersrand in South Africa have reported a review of research on residual stresses in carbon steel welding: formation mechanisms, mitigation strategies, and advances in advanced post weld heat treatment technologies. The relevant paper titled "A comprehensive review of residual stresses in carbon steel welding: formation mechanisms, mitigation strategies, and ...
LiDAR sensors are crucial for implementing modern technologies such as autonomous driving, AR/VR, and advanced driving assistance systems. For example, more accurate shape detection in AR/VR devices and smartphones depends on the improved range resolution of medium and short range LiDAR. This requires a single photon detector with improved timing jitter performance.LiDAR calculates the distance an...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
