Description and video

Full compatibility with 3D printers

Renu 400 is designed for flexible integration into any additive manufacturing environment.

The device combines two steps in one. Connected to any standard industrial vacuum cleaner, it vacuums the powder from the printer and automatically sieves it, with a flow rate of up to 100 kg per hour. This reduces machine downtime and keeps operator contact with powder to an absolute minimum.

A large 400 mm sieve diameter and two independent vibration sources, mechanical and ultrasonic, provide excellent sifting efficiency and prevent the mesh from blinding with fine particles. Powder outlets can be adapted to standard and custom container connectors. Renu 400 is also available in an inert version for reactive metal powders.

Benefits

Do not waste time on manual sieving

  • Efficiency

    Up to 100 kg of powder per hour, an ideal solution for medium and large-scale additive manufacturing.

  • Automation

    The complete sieving cycle takes place without manual intervention, significantly shortening operating time and reducing workload.

  • Closed loop

    Sieving in a closed system minimizes operator contact with powder and reduces material loss.

  • Easy integration

    The compact design allows for easy integration into existing production lines or powder recycling systems.

  • Materials

    Compatible with a wide range of metal powders, e.g. stainless steel, titanium, Inconel and aluminium.

  • Mobility

    Wheel-based frame allows for easy movement.

Increase work time efficiency

Manual sieving is time-consuming and labor-intensive. Our system works autonomously, allowing for optimal use of human resources.

  • Error reduction: automation minimizes the risk of errors caused by improper manual handling, such as insufficient cleaning or excessive powder loss.
  • Repeatable quality: consistent operating parameters ensure uniform powder granulation, improving 3D printing process control and print quality.
  • Safety and ergonomics: the automatic sieving machine eliminates direct operator contact with fine, often toxic metal powder. This reduces dust exposure and meets higher occupational health and safety standards.

FAQ

Frequently asked questions about Renu 400

What metal powders can be sieved with Renu 400?

Renu 400 handles a wide range of powders used in 3D printing, including stainless steel, titanium, aluminium, Inconel, cobalt-chrome, and other materials used in LPBF and SLS technologies.

Is Renu 400 compatible with any 3D printer?

Yes. The device is designed for easy integration with various 3D printers, regardless of manufacturer. Thanks to modular construction and universal connectors, integration with existing production systems requires no hardware modifications.

Do the sieves inside the machine require replacement or periodic cleaning?

No. We have used one of our sievers daily for several months without any clogging of the sieves.

Can sieves with different mesh sizes be installed in the Renu 400?

Yes. If your application requires a different powder granulation, we can provide the appropriate type of sieves.

Can Renu 400 be used in small labs or startups?

Yes. Its compact and mobile design allows for easy implementation even in limited spaces without major infrastructure investments.
