How are 3D printing powders sieved?

3D printing powders are sieved with vibrating screens to separate out-of-specification particles and achieve a uniform particle size. This process ensures better print quality and greater material stability.

Why is particle size important for additive manufacturing powders?

A controlled particle size of additive manufacturing powders ensures uniform material deposition and proper melting during the process. Non-uniform powders can compromise the quality of the finished part.

How to recover and reuse powders in 3D printing?

Unmelted powders can be recovered and sieved to remove contaminants and oversized particles, allowing the material to be reused in the 3D printing production cycle.

How to remove contaminations in 3D printing powders?

The use of vibrating screens allows impurities and agglomerates to be removed, maintaining the high quality standards required in additive manufacturing processes.

What machines are used for 3D powder treatment?

For 3D powder treatment, control and classification vibrating screens are used, possibly combined with ultrasonic systems, to ensure precise separation and consistent material quality.

Additive Industry \ 3D

In the field of additive industry and 3D printing, powder management is a crucial step in ensuring the quality of the finished product and the efficiency of the entire production process. Powders, whether metallic or polymeric, must be treated with extreme precision to ensure an optimal particle size distribution, which is essential to obtain repeatable results and comply with the standards required by the most advanced additive technologies.

Vibrowest, with its long experience in the design of sieving and separation systems, has developed specific solutions to meet the needs of this constantly evolving sector. Our plants allow us to treat both virgin dust, eliminating impurities and agglomerates, and those already used, separating out-of-specification particles that can be recovered, requalified and re-introduced into the production cycle with the same functional characteristics of the new material.

Thanks to the use of technologies such as the ultrasonic vibration of our Vibrowest Ultrasonic 3.0 system, we avoid clogging of the meshes during sieving, improving yield and reducing downtime. In addition, integration with controlled environments, even in an inert atmosphere or ATEX certified, allows to operate in total safety, even with sensitive or reactive materials.

Each Vibrowest solution is designed to adapt to the specific needs of the customer, both in the field of research and development and in high-productivity industrial contexts. The goal is always the same: to ensure strict control of the material, reduce waste and ensure the highest quality of feedstock for 3D printing.
