In order to prevent fires and combustible dust explosion hazards from 3D printing dust, GE Aviation required a solution that would protect their workforce from the dangers of explosive dust.
GE Aviation’s additive manufacturing facility in Cincinnati Ohio is focused on producing 3D printed parts for use in advanced turbofan jet engines. One of the parts produced is a 3D printed fuel nozzle, a critical component of the LEAP jet engine. The plant uses a variety of different 3D printing machines including Direct Metal Laser Sintering (DMLS), Electron-beam melting (EBM), Selective Laser Melting (SLM) along with other types of 3D printing processes.
3D printed parts used in turbofan jet engines are frequently produced from exotic metal alloys including, aluminum, titanium, magnesium, cobalt chrome and stainless steel. In order to prevent fires and combustible dust explosion hazards from 3D printing dust, GE Aviation required a solution that would protect their workforce from the dangers of explosive dust.
Following a site visit by Diversitech’s local representative, a wet downdraft table system was custom-designed for GE Aviation’s specific deburring and finishing application. This table was divided into 6 workstations, each with a work area 32” deep by 42” wide. To contain the airborne dust, side and back walls along with middle dividers were added. The tables were ducted to two W5000 CFM wet dust collectors with dual silencers and hydrogen vent fans. The dust collectors and vent fans serve to exhaust flammable hydrogen gas produced as the metal dust oxidizes in the collector’s water reservoir.
The downdraft table was ergonomically designed for operators to comfortably sit at the table, which allows kick space for their legs. For added safety, explosion-proof light kits were installed in each work cell. In order to reduce noise levels that are harmful to workers, sound attenuation media were installed on the inner walls. A blue cushion grid mat was also placed on the surface of the steel bar grating to prevent parts from getting damaged or scratched.
Diversitech’s application engineering department is capable of providing a tailored solution for your 3D printing finishing dust collection application and can custom design a downdraft table work area to meet your specific needs. Companies know that combustible metal dust is a serious workplace hazard and that employees and property need to be protected from the risk of dust fires and explosions. Diversitech has the experience and the team to design the right dust collection system to suit your specific needs.
It is well known that combustible metal dust is a serious workplace hazard. Since industrial dust is in fact the leading cause of workplace fires and explosions, employees and property need to be protected from such risks.
GE Aviation and other companies are now protected through solutions designed by Diversitech. Our team, with all our collective experience, offers you the right dust collection system and downdraft table work areas customized to meet your specific needs. Our application engineering department can provide you a solution tailored for your 3D printing finishing dust collection application as well.
