Powder Sieve - Automatic Sieve Shaker

The fact that a high percentage (between 50% and 100%) of the material used in 3D SLS printing is reused, implies that the condition in which it is found becomes a critical factor.

The powder must have a high homogeneity, without aggregates or impurities. Also, the mix between reused material and refreshment material should be as uniform as possible. In this way it is achieved not only that the print quality is optimal, but also the mechanical properties of the printed part.

Achieving the highest degree of homogeneity in the material, as well as correct screening, can be difficult to achieve with manual means, in addition to being a waste of time and human resources.

This is where SinteritPowderSieve comes in, a system that uniformly sifts and mixes reused material and soft drink material. In addition, the ready-to-print powder is poured directly into a suitable container for storage, which minimizes the exposure of the material to air, something of great importance due to the high hygroscopicity of some materials such as polyamide.

The entire process takes place indoors, helping to keep the workspace clean while minimizing operator exposure to suspended dust.

For all this SinteritPowderSieve becomes an essential accessory for any SLS printer, especially Lisa and Lisa Pro.
