DTU Construct Speeds Up Metal Powder Sieving for 3D Printing
Researchers at DTU Construct have developed a new method to significantly accelerate the sieving process for metal powders used in 3D printing.
Traditional methods for sieving metal powders for additive manufacturing can be time-consuming, often taking hours to process sufficient quantities. This bottleneck can slow down production and increase costs.
To address this, a team at DTU Construct has devised an innovative approach that utilizes an electric field. This method applies an electrostatic charge to the powder particles, which then repel each other. This repulsion reduces agglomeration and allows the powder to pass through the sieve mesh much more efficiently.
The new technique has demonstrated a substantial increase in sieving speed, reportedly reducing the processing time from hours to mere minutes for a given batch of powder. This acceleration is crucial for industries relying on rapid powder preparation for 3D printing applications.
The researchers believe this electrified sieving method has the potential to become a standard in the additive manufacturing industry, offering a more efficient and cost-effective way to prepare metal powders for various printing processes.
This development is significant because efficient powder handling is a critical, often overlooked, aspect of metal additive manufacturing. Accelerating the sieving process directly impacts throughput and cost-effectiveness, potentially enabling wider adoption of metal 3D printing in high-volume production scenarios. This innovation contributes to the broader industry push for faster, more automated, and scalable AM workflows.
