FAQ Section

What is Additive Manufacturing?

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

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.

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.

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.

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.

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.

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

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
