Characteristics of Powder for Multi-Laser Printing

The characteristics of metal powders are just as critical as their compositions. These characteristics impact the printing process, the mechanical properties of the printed parts, and the overall success of the multi-laser printing operation.

特徴説明
粒度分布Uniform particle size distribution ensures consistent flowability and packing density, crucial for layer-by-layer printing.
球形度Spherical particles promote better flowability and packing, reducing the likelihood of defects in the printed part.
純度High purity minimizes contamination, which can lead to defects or reduced performance in the final part.
見かけ密度Higher apparent density can improve the mechanical properties of the final part, as it leads to fewer voids and defects.
流動性Good flowability is essential for consistent powder distribution during the printing process, affecting build quality and reliability.
Moisture ContentLow moisture content is critical to prevent oxidation or other reactions that could compromise the powder’s performance.
酸素含有量Control of oxygen levels is vital, especially in reactive materials like titanium, where high oxygen can lead to embrittlement.
Chemical HomogeneityEnsures uniform mechanical properties throughout the printed part, preventing weak spots or inconsistencies.
Surface TextureSmooth surface texture reduces friction between particles, enhancing flowability and layer cohesion during printing.

Understanding these characteristics is key to selecting the right powder for your specific application, ensuring optimal performance and quality.
