Kason 3D-ReKlaimer Recovers Metal 3D Printing Powder

Kason’s dust-tight, fully automated 3D-ReKlaimer metal powder recovery system for 3D printing recovers and reconditions used powders to exacting particle sizes, reducing waste and lowering operating costs while preventing contamination of the product and plant environment. The system is offered in custom configurations to suit various additive manufacturing processes requirements.

A 24" (610-mm-diameter) Vibroscreen vibratory screener imparts multi-plane, inertial vibration that causes on-size metal powder particles to pass through apertures in the screen, and oversize particles to travel across the screen surface into a sealed container. A Kasonic ultrasonic anti-blinding device transmits ultrasonic frequencies to the screen, allowing sifting as fine as 25 microns/500 mesh with no screen blinding. The closed-loop system can be purged with inert gas to isolate contamination-sensitive powders from ambient air and moisture.

The unit can accept bottles of used powder connected manually, or through an optional integral vacuum conveying system that automatically transfers used powders from the build chamber into a filter receiver/hopper located above the screening chamber of the 3D-ReKlaimer system.

Similarly, screened powders ready for reuse can be discharged into bottles for manual connection to the inlet of 3D printers, or can be transferred automatically by an integral pneumatic conveyor that discharges into a filter receiver/hopper located above the 3D printer inlet.

The self-contained 3D-ReKlaimer system is ready to connect and run, and can serve multiple 3D printing stations when equipped with casters. Automated controls with an HMI simplify operation and minimize involvement of plant personnel. The unit’s stainless steel construction finished to sanitary standards eliminates dead spots, allowing total evacuation and easy cleaning. Optional HEPA filtration and ground resistance monitoring further enhances emission containment and operator safety.
