EBM also tends produce metal parts with a lower level of accuracy when compared to SLM and DMLS. This is because the layer thickness in the SLM process is typically thinner (between 20 and 100 microns) than in the EBM (between 50 and 200 …
Sintering or frittage is the process of compacting and forming a solid mass of material by pressure or heat without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the … Zobacz więcej Sintering is generally considered successful when the process reduces porosity and enhances properties such as strength, electrical conductivity, translucency and thermal conductivity. In some special … Zobacz więcej Most, if not all, metals can be sintered. This applies especially to pure metals produced in vacuum which suffer no surface contamination. Sintering under atmospheric … Zobacz więcej For materials that are difficult to sinter, a process called liquid phase sintering is commonly used.
