Selective laser melting (SLM) is a popular metal additive manufacturing (AM) technique. It has attracted a lot of interests in many areas such as aerospace, automotive, biomedical, and so on [[1], [2], [3]]. In the SLM process, a high intensity laser is applied as the heat source to melt selective regions of powder material in a layer-by-layer way.Abstract: This study explores important chip-level bonding structures for heterogeneous integration in microelectronics, focusing on Cu-Cu and Cu/SiO 2 hybrid bonding. Structure I investigates Cu-Cu bonding, while structure II demonstrates Cu/SiO 2 hybrid bonding with area-selective metal passivation. The research highlights the significance of anti-oxidationġ . This study aims to improve the quality of titanium alloy structural components by introducing a remelting process into conventional selective laser melting (SLM) fabrication. The purpose of this paper is to study the implementation of a commercial piezoelectric printhead in the fabrication of high-resolution metal parts selective inhibition sintering (SIS-metal). SIS is a disruptive platform additive manufacturing (AM) process capable of printing parts from polymer, metal and ceramic base materials.
Selective laser melting (SLM) is one of the most concerning additive manufacturing (AM) technologies, which can directly fabricate parts by spreading and melting powder layer by layer [6].It allows the production of hollow, porous, lattice, heterogeneous materials, and functionally graded parts, which offer high design freedom, simple fabrication, and efficient .quality that is exact — a state that can be defined, verified, and reproduced again and again. . CONFORM TO QUALITY STANDARDS In metal parts manufacturing, as well as many other industries, ISO 9000 guidelines are used in establishing, documenting, and supporting quality control methods. In addition, there are ISO standards for areas such . As one of these promising additive manufacturing approaches, selective laser melting (SLM) technology uses high-intensity lasers as an energy source to melt and fuse selective regions layer by layer in a metal powder bed, which facilitates manufacturing bulk structures with novel and complex designs [8].
Selective laser melting (SLM) is a powder-bed-fusion AM process whereby a high-density-focused laser beam selectively scans a powder bed and those scanned and solidified layers are stacked upon each other to build a fully functional three-dimensional part, tool, or prototype [1].As shown in Fig. 3.1, SLM is very similar to the selective laser sintering (SLS) .

To achieve high-quality metal parts fabrication, you’ll need to follow a structured approach that guarantees precision and durability at each stage. It all starts with selecting the right materials, which lays the foundation for effective design planning. From there, you move on to precision cutting and forming techniques, which shape your components with accuracy. The pore defects are caused by metal evaporation. This phenomenon has also been reported in SLM with high energy density for the fabrication of NiTi or Ti-6Al-4 V [Citation 26, Citation 40–42]. At higher scanning speeds, the reduced interaction time as well as irregular laser tracks may not obtain complete powder melting and proper fusion in . To guarantee accurate fabrication of the template for cervical vertebra operation, the contact face was placed upwards to improve the joint quality between the template and the cervical vertebra. The joint surface of the printed template had a roughness of Ra = 13 ± 2 μm. After abrasive blasting, the surface roughness was Ra = 7 ± 0.5 μm.

The following quality documents are available for all our manufacturing . Successful production of metallic selective laser melting components requires a quality assurance process that can effectively and nondestructively assess internal defects. The results obtained indicated that the quality of the materials produced, which is a function of the finish requirement, depends on the print quality and the independent process parameters and .1. Introduction. Honeycomb films have attracted considerable interest due to their numerous potential applications in the fields of size-selective separations [], superhydrophobic surfaces [], catalysis sensors [], and so on.Although there are many methods for preparing porous films with different pore sizes, shapes, and morphologies, the breath figure (BF) method is a simple and .
As a Quality Engineer in a metal fabrication factory, you are tasked to evaluate samples of the fabricated metal parts from a new machine. You are using a single sampling plan of lot size of 1500 units, the sample size of 110 units, and the acceptance number of 3. i) Construct the operating characteristic curve using 7 points They define the permissible limits of variation in a physical dimension which is a very crucial quality metric in sheet metal fabrication drawings.

It outlines general tolerances for various aspects . A bespoke metal truncheon artefact with inclination angles varying from 0° to 180° was built by selective laser melting. Focus variation microscopy was used to measure the topography of inclined . What is sheet metal fabrication? Sheet metal fabrication is a complex process of turning flat sheets of metal into products via cutting, punching, folding and assembling. Metal is cut, bent or stretched into the desired shape using special tools; band saws, cutting torches, chop saws, press brakes, oxy-acetylene torches and welding equipment.
Like LPBF 3D printing, selective laser melting works by fusing materials across layers, creating three-dimensional metal parts that work for different functionalities.
