“…Selective laser sintering (SLS) is one of the new rapid prototyping, tooling, and manufacturing technique with cost-efficient for a lot of applications such as automotive, aviation, mold, and machinery [1,2]. SLS has now been become an effective method for fabricating a number of various complex shapes, on not only metals but also polymers and even ceramics [3] compared to other sintering methods [4,5]. Additive manufacturing (AM) processes were initially proposed for producing prototypes, but in a few decades, their use changed and nowadays they are also employed for the fabrication of functional and structural parts for applying in industrial and medical fields.…”

Selective laser sintering (SLS) is a type of laminating sintering technique, using CO2laser with (metal, polymer, and ceramic) powders. In this result, the flake SUS 316L was used to achieve a high porous product, and compare to spherical type. After SLS, the porosity of flake-type sample with 34% was quite higher than that of the spherical-type one that had only 11%. The surface roughness of the flake SLS sample were also investigated in both inner and surface parts. The results show that the deviation of the roughness of the surface part is about 64.40μm, while that of the internal one was about 117.65μm, which presents the containing of high porosity in the uneven surfaces. With the process using spherical powder, the sample was quite dense, however, some initial particles still remained as a result of less energy received at the beneath of the processing layer.

Mechanical ball milling was used to coat SiO2 nanopowder on a Fe-Si-B amorphous powder in this study. The Fe-Si-B/SiO2 core–shell amorphous composite powder was obtained after 6h of ball milling. At 490 °C, the amorphous powder is thermally stable. Discharge plasma sintering was used to create a Fe-Si-B/SiO2 magnetic powder core (SPS). At a sintering temperature of 420 to 540 °C, the phase composition and magnetic characteristics of the magnetic particle core were investigated. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to examine the structural features of the magnetic particle core. A precision resistance tester and a vibrating sample magnetometer were used to assess the resistivity and magnetic characteristics of the magnetic particle core. The findings showed that Fe3Si and Fe2B are the phases generated during spark plasma sintering. High-frequency power loss increases as density rises. However, at the measured frequency, the magnetic permeability of the magnetic particle core changes slightly and has excellent frequency characteristics, making it appropriate for use in high-frequency components.
