Metal sintering 3D printer (SLM)

Metal sintering (SLM) is a 3D printing technology that uses metal powder to directly print metal parts. When printing, the scraper spreads a layer of metal powder on the base plate of the forming cylinder, and the laser beam will selectively melt the powder according to the cross-sectional profile of each layer of the part to process the current layer. After one layer of sintering is completed, the lifting system lowers the height of one cross-section layer. The powder spreading roller spreads another layer of metal powder on the formed cross-section layer and sinters the next layer. This is done layer by layer until the entire part is sintered. The entire molding process is carried out in a processing chamber that is evacuated or filled with protective gas to prevent the metal from reacting with other gases at high temperatures.

1. Molded parts have better surface quality without polishing.
2. The molded parts have high precision and are used to make precision prototypes.
3. Directly manufacture metal functional parts without intermediate processes, greatly simplifying the production process.
4. It has a metallurgical structure, high density (>99%), excellent mechanical properties, and can eliminate the need for post-processing.
5. Parts can be fabricated in minutes to hours, depending on the size and complexity of the part
Functional parts with complex geometric shapes (such as snap fits, and living hinges) can be directly manufactured.
6. The material has a wide range of applications, and its metal powder can be a variety of single materials or multi-component materials.
7. Particularly suitable for customized manufacturing of single or small-batch functional parts
