Industrial Vacuum Cleaners for Additive Manufacturing

Additive manufacturing, also known as 3D printing, is becoming increasingly popular in the metalworking industry. Among the various technologies, powder bed fusion technology makes extensive use of metal or polymer powders to print prototypes or products.

Industrial vacuum cleaners for additive manufacturing are designed to effectively and safely collect unused powder during the printing process and eventually feed it back into the production cycle, providing cost savings on powder repurchase and maximum simplicity in handling those to be disposed of.

Industrial vacuum cleaners for powder bed fusion technology: which functions?

Industrial vacuums for powder bed fusion processes can have several applications:

To clean the inside and outside of the printer after each work cycle
To vacuum residual powders inside the printing chamber
To vacuum up airborne dust during final cleaning operations of the manufactured part

Metal powder vacuum cleaners in powder bed fusion printers

Unused powder inside the 3D powder bed fusion printer must be vacuumed safely with appropriate equipment to avoid explosion. Depending on the equipment used it will be possible to:

Inerting the metal powder: a sophisticated collection system that immerses the collected powder in an inert liquid, eliminating any risk of explosion and allowing safe disposal of the now inert powder.
Powder recovery: the collected powder enters an explosion-proof (1D, Atex-certified) container, making it safe to be reused after an appropriate sieving process aimed at filtering out the powders that can still be used.

How to inert the metal dust vacuumed up?

The vacuumed powders are immediately immersed in an oil bath that renders them immediately inert, eliminating any risk in the subsequent management of the powders, which must then be disposed of according to current regulations.

Industrial vacuum cleaners for polymer dusts

Unused polymer powders in and around the 3d printer must be collected with appropriate antistatic equipment to avoid any possible source of ignition.

Compact, Atex-certified industrial vacuum cleaners are used to perform this type of operation to ensure maximum safety and complete grounding of the system.
