3D Printing powder are metal powders that are reduced to fine particles. 3D printing metal powder are the the preliminary base materials for most 3D printing processes that produce metallic parts. 3D printing, also known as additive manufacturing (AM), is the manufacturing of parts and products in a layer-by-layer fashion. Both the characteristics of the metal powder and the type of the 3D printing process determine the properties of the end product. Powder characterization takes place depending on the way it is produced, which may result in different particle morphology and purity. How to select 3D printing powders? Different 3D printing equipment and forming processes require different particle size distributions. At present, the powder size range commonly used for metal 3D printing is 15-53 μm (fine powder), 53-105 μm (large particle size), and in some cases, it can be relaxed to 105-150 μm (larger particle size). The choice of powder 3d printing particle size for 3D printing is mainly based on metal printers with different energy sources. The printer using laser as the energy source is suitable for the use of powder of 15-53 μm as a consumable material because of its fine focusing spot, which is easy to melt fine powder, and the powder supply method is layer-by-layer powdering; The powder-printing printer with electron beam as the energy source has a slightly focused spot, which is more suitable for melting coarse powder, and is suitable for using coarse powder of 53-105 μm; For a coaxial powder feeding type printer, a powder having a particle size of 105 to 150 μm can be used as a consumable.

“Water reduction” mechanism of polycarboxylic ether based superplasticizers

Today’s concrete superplasticizers These are basically made from a combination of various materials like polycarboxylate water–reducing mother liquor and/or polycarboxylate shrink-preserving mother liquor. It is the most important role for water-reducing mothers in superplasticizer. Although it is possible that the quantity of the mother solution may change with the changes in concrete, I’ve never seen …
