How to Reuse Metal Powder in 3D Printing?

Metal 3D printing uses fine metal powders to manufacture complex components. However, after printing, the remaining powder may contain agglomerates, oversized particles, or particles that do not meet the required size specifications. Reusing this powder without proper screening can affect powder quality and consistency in subsequent production cycles.

Ultrasonic powder sieving helps recover usable metal powder by improving particle separation and reducing screen blockage.

The Challenge: Screening Remaining Metal Powder

Conventional sieving methods can face difficulties when handling fine metal powders. Small particles may clog the mesh, reducing throughput and making it harder to achieve consistent particle-size separation.

This can lead to slower powder recovery, increased manual intervention, and unnecessary material waste.

The Solution: RTUL Ultrasonic Powder Sieving

RTUL’s ULTRASCREEN ultrasonic sieving technology applies high-frequency mechanical oscillations to the sieve mesh. These oscillations help reduce mesh blockage and improve the screening of fine powders.

When integrated with a suitable screening machine, the technology can help separate reusable metal powder from oversized particles and agglomerates, subject to the powder specifications and process requirements.

Key Benefits

  • Reduced mesh blockage: Helps maintain consistent powder flow.
  • Improved screening efficiency: Supports effective separation of fine particles.
  • Higher powder recovery: Helps reduce losses during screening.
  • Consistent particle separation: Supports better control of powder quality.
  • Easy integration: Can be retrofitted to compatible existing vibratory screening machines.
  • Reduced maintenance: Minimizes the need for frequent mechanical mesh-cleaning interventions.

Where Can This Technology Be Used?

Ultrasonic powder sieving can be used for suitable metal powders in additive manufacturing, as well as ceramic powders, powder coatings, pharmaceutical materials, and food additives.

Before reuse, recovered metal powder should be checked against the required particle-size distribution, material condition, and process specifications. Sieving alone does not guarantee that the powder is suitable for another printing cycle.

Why are concrete testing machines the backbone for infrastructure companies?

Image
Concrete is a ubiquitous material used for different infrastructure projects. Its strength and longevity depend heavily on its quality. This is where a concrete testing machine comes in. In the construction industry it plays a vital role in ensuring the structural integrity of concrete: be it in its fresh state (before hardening), molded cylinders, or precast beams. Subjecting concrete samples to controlled stress and strain by these machines is essential. It can determine key properties like compressive strength, flexural strength, and elasticity. This data helps assess the concrete’s ability to withstand weight, bending, and other stresses it will encounter in its service life. Some professionals also call it the pulse velocity test of concrete. Why are concrete testing machines the backbone for infrastructure companies? This blog post discusses the need for a concrete testing machine if the problem goes beyond basic strength testing. Modern concrete testing machines are equipped wit...
