3D printers are much like your typical inkjet printer, except instead of putting a layer of ink on a page, they place layer upon layer of a material typically a molten layer of polymer. When completed, these layers form a 3D object. According to 3DPrinting.com, several different technologies are commonly used including: vat photo polymerization,
Here at Dual Draw, we're fascinated by dust. It's everywhere, and has been since the dawn of time. Layer upon layer upon layer of dust have buried civilizations. These layers, over the eons, tell us the story of earth -- if we're willing to look. Where Dust Comes From As you run your finger over
Here at Dual Draw, we’ve talked a lot about combustible dust, and how people expose themselves to danger without even knowing they may be in harms way. We have posted about requirements you should know about when handling combustible dust, as well as some methods of controlling them. We have yet to discuss the different

Metal Fume Fever: Every Industrial Worker’s Enemy Industrial manufacturing processes often produce fumes that can easily harm the health of the workers if not controlled. A common condition experienced in a manufacturing setting by operators is metal fume fever. This illness presents influenza-type symptoms. There are no specific signs of metal fume poisoning, but are mostly flu-like. Signs and
A little dust here and there might not seem like that big of a deal; frequently operators work longer than they should without adequate air filtration or safety masks. From drilling, sawing, grinding, sanding, chiseling, cabling and even sweeping, however, the activities inside construction sites produce an extremely dangerous amount of dust. In fact, in a recent survey conducted
