AbstractDue to the width of the laser melt pool and the sintering effect on the surrounding powder, the experimental size of the selective laser melting (SLM) sample will be larger than the design size, which will greatly affect the dimensional accuracy and surface quality of the thin-walled sample. In order to obtain SLM thin-walled TC11 specimens with precise dimensions, an orthogonal experiment...
Recently, metal 3D printing manufacturer Meltio launched its latest metal 3D printer - M600. This M600 has shown significant progress in integrating into industrial manufacturing processes, no longer limited to niche applications. Like most of Meltio's product lines, the design of M600 was originally intended to address common manufacturing issues such as long delivery times, high inventory cost...
In 2017, the detection of gravitational waves generated by the merger of binary neutron stars marked a significant breakthrough in physics. These waves reveal important information about the universe, from the origin of short gamma ray bursts to the formation of heavy elements.However, capturing gravitational waves from the merged residue remains a challenge as these waves avoid the detection rang...
Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in evaluating the laser damage resistance and damage mechanism of 532nm thin film polarizers using different laser damage test protocols. The related achievements were published in Optical Materi...
Surface acoustic wave technology is renowned for its high precision and fast driving, which is crucial for microfluidics and affects a wide range of research fields. However, traditional manufacturing methods are time-consuming, complex, and require expensive cleanroom facilities.A new method overcomes these limitations by utilizing aerosol jet printing to create customized equipment with various ...
