Volkmann’s Enclosed 3D Printing Conveyors Prevent Metallic Dust Hazard

Volkmann metal powder conveyors for 3D printing feature an explosion-proof design that helps metal additive manufacturers (AM) comply with the forthcoming NFPA 660 Standard for Combustible Dusts and Particulate Solids Chapter 12 covering combustible metals.

Eliminating electrostatic charges as a potential ignition source, the Volkmann pneumatic vacuum conveyors automatically transfer the ignitable metal powders from storage to 3D printers within an enclosed, sealed system for safe, smooth powder transfer without using electricity and without generating heat. The potential for metallic powders to escape the closed system as a fuel source is also eliminated.

The metal powder conveyors have earned ATEX certification as proven safe for use in potentially explosive atmospheres in both normal air environments and under inert conditions as an option. The vacuum conveying system is suitable for transferring cobalt, tungsten, iron, silver powder, alumina, stainless steel, copper, nickel chrome, titanium and other metal AM powders.

The Volkmann vacuum conveyors may be installed as part of a complete, automated system integrating metal powder handling, transfer, extraction, sieving and reprocessing. The material handling system may serve one or many 3D printers.
