Additive Manufacturing Material Handling and Recovery System

Typical Loading and Unloading Application

Vacuum Conveyor

Load. Unload. Return to Use.

Mobile or Fixed Support

The Additive Manufacturing Material Handling System (AMMHAS) is designed to enhance the new technology of additive manufacturing machines when handling metal powders or toxic materials. Consisting of three elements, the Volkmann AMMHAS addresses the need to transfer material to the machine — both in a normal air environment or under an inert gas — recover the unused material, screen it, and finally return the material to the machine or a container for future use.

Ultrasonic Screener

Inert Gas or Normal Atmosphere Two options are provided (both with high levels of containment) to meet requirements due to potential environmental issues, operator safety, and applications using inert gases. Where inert transfer is required, the system is designed in a “closed loop” so that inert gas is both contained and reused, avoiding the additional cost of large volumes of inert gas. In this version, a special configuration gas-tight electric pump is used to maintain system temperature and containment.

Trials Throughput, performance of the conveyor, and screening system throughput will depend on the product characteristics. Because of this, Volkmann recommends that trials on the respective material be conducted in advance at our test facility. Please cont
