3D Printing Dusts - Explosive Metal Dusts.

3DPrintingVacsREV

Vacuums for the safe recovery of metal dusts and dusts from 3D Printing.

The 3D printing process builds a three-dimensional object from a computer-aided design model, usually by successively adding material layer by layer, which is why it is also called additive manufacturing. Control of fugitive dust and housekeeping and cleaning around the 3D printing equipment must also be considered.

The integrated cyclonic pre-seperator can separate over 98% of the powder before it enters the vacuum.

We have a complete range of small, medium and large vacuum cleaners for aluminum and titanium dusts, additive manufacturing and 3D printing. Our Explosion-Proof Wet Immersion Separators for aluminum, titanium and other explosive metal dusts are NRTL certified for Division 1 and Group E. We offer both immersion “wet mix” systems as well as dry recovery systems; available in electrically operated or pneumatic (air operated) versions. We offer several equipment protection levels such as Dust Ignition Protected as well as Explosion Proof / Dust Ignition Proof Hazloc vacuum cleaners.

FAQ. Click the + sign to see the answer.

Plus (click or tap to expand) + What is Additive Manufacturing?

​Additive Manufacturing, more commonly known as 3D printing. (RP), Direct Digital Manufacturing (DDM) and Additive Fabrication (AF)

Plus (click or tap to expand) + Why is vacuuming dusts from Additive Manufacturing and 3D printing so important?

The 3D printers used in additive manufacturing usually require cleaning after the process is completed as the dusts can be explosive. Some explosive dusts also interact badly with other explosive dusts. Control of fugitive dust emissions and housekeeping outside of (and around) the 3D printing equipment must also be considered.

Plus (click or tap to expand) + Why is it important to do a Risk Analysis / Risk assessment?

Whether the powders or materials used are metal or nonmetal, it is imperative that anyone considering using additive manufacturing perform a risk analysis on the process to determine the hazards involved and how those hazards will be managed.

Plus (click or tap to expand) + What kind of Vacuum cleaners are recommended for use in Additive Manufacturing and 3D Printing?

Controlled Air Design offers a complete line of vacuum cleaners for additive manufacturing and 3D Printing. We offer both immersion “wet mix” systems as well as dry recovery systems.

Plus (click or tap to expand) + What materials are used in additive manufacturing?

The materials used in additive manufacturing can range from starch to photopolymer resins (polymer changes properties when exposed to light) to thermoplastics to metals, such as aluminum, titanium, stainless steel, Inconel alloys, and others.

Plus (click or tap to expand) + What type of Wet Immersion Separator Vac should I get for explosive metal dusts like titanium and aluminum?

Make sure the vacuum model is CSA certified (or other accredited testing lab) and recognized by NRTL for: Class I, Division 1, Division 2, Group D, T3C and Class II, Division 1, Division 2, Groups E, F and G. Call us at (800) 635 0298 any time if you have any questions on this.

Plus (click or tap to expand) + What is NRTL?

OSHA created the Nationally Recognized Testing Lab (NRTL) program to ensure that certain types of equipment be tested and certified for their safe use in the workplace. A Nationally Recognized Testing Laboratory (NRTL) is a private-sector organization that OSHA has recognized as meeting the legal requirements in 29 CFR 1910.7 to perform testing and certification of products using consensus based test standards. An organization must have the necessary capability both as a product safety testing laboratory and as a product certification body to receive OSHA recognition as an NRTL. To find out more about the OSHA NRTL program, please follow this link to the OSHA website: https://www.osha.gov/dts/otpca/nrtl/nrtllist.html

Plus (click or tap to expand) + What are "conductive vacuum tools and hose"? and what is the difference between a grounded hose and a hose that conducts static?

​In the old days people would run a copper wire inside the hose, or buried within the hose helix, and belive they were dissipating static electricity. It never really worked that well. The word “static” tells us what really happens: the “static” stays where it is and the copper wire really only serves as an additional path to ground. Our Static Conductive Vac Tools and Hoses are impregnated with a high concentration of conductive resins, such as carbon black and various conductive urethane resins. Our Statmax Conductive vac hoses specification sheets contain resistance readings that show the concentarion of conductive resins used: https://www.controlledairdesign.com/images/uploads/files/StatMax_YL_1.pdf

For applications where a grounding wire is called for we have the food grade StatMax with copper grounding wire: https://www.controlledairdesign.com/products/hoses-tools/statmax-grounded
