Additive Manufacturing Metal

Metal powder classification for 3D printing

With its classifiers for powder manufacture, which have already proved their worth a hundred times over in successful use, Hosokawa Alpine develops unique technologies for the widest array of industries. The machines, designed for extremely precise classification and simplest cleaning, have now been specifically adapted to the requirements of metal powder production.

PERFECT METAL POWDERS CALL FOR OPTIMUM CLASSIFICATION

Conventional sieving machines remove the coarse particles that accumulate during atomisation of the metal powder in a pre-classification step. This technology, however, soon encounters its limits when flexible separation cuts, inert gas operation or more frequent product changes are required. An optimum solution is now available: an air classifying system with a Hosokawa Alpine Turboplex ATP classifier.

The tried-and-trusted Hosokawa Alpine Turboplex ATP provides flexible separation cuts in the range of 5 to 120 µm
Available in many different machine scales, matching the atomizer output rate
Inert gas operation with argon or nitrogen

Particle size distribution of a classified Titanum-/Alloy-Powder
