What is Additive Manufacturing?
Additive Manufacturing, more commonly known as 3D Printing, is also referred to as Rapid Prototyping (RP), Direct Digital Manufacturing (DDM) and Additive Fabrication (AF).
It is a revolutionary manufacturing method for producing parts with complex geometries, low-volume manufacturing runs and prototypes. This method replaces traditional and typically more labor-intensive manufacturing methods, including subtractive manufacturing (cutting away and removing unneeded material) and forming and casting.
The additive manufacturing process generally involves adding thin layers of powdered material and using devices such as high-powered lasers to sinter or melt each layer to fuse it to the part being constructed. This process is based on CAD 3D models that are used as a guide or map for the process. 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.
The importance of 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 / Risk Assessment on the process to determine the hazards involved and how those hazards will be managed. This analysis is a requirement for any combustible dusts used in the manufacturing process. The 3D printers used in additive manufacturing usually require cleaning after the process is completed. Control of fugitive dust emissions and housekeeping outside of (and around) the 3D printing equipment must also be considered.
Vacuum systems for use in Additive Manufacturing and 3D Printing:
The 3D printers used in additive manufacturing usually require cleaning after the process is completed. Most cleaning protocols include vacuuming with a portable vacuum system. Vacuum cleaning is also required to handle fugitive dust and for housekeeping near the additive manufacturing process.
Tiger-Vac manufacturers a complete line of Mini Immersion “Wet Mix” separators for additive manufacturing and 3D Printing. Our Mini Immersion systems are 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).
Our Mini Immersion “Wet Mix” vacuum systems are designed for the recovery and neutralization of combustible metal dusts in a liquid bath. This includes: aluminum, magnesium, tantalum, titanium and zirconium. These immersion systems comply with NFPA Standard 484 and meet NFPA requirements for the recovery of combustible metal dusts.
