3D printing is a new enough technology that there's still plenty of debate about how safe it is, on a number of levels. While some fears may be over-exaggerated, there's still reason for legitimate concern, particularly in regards to factors such as 3D printer emissions. It's a known issue that 3D printers can give off some not-so-healthy chemicals and particles while printing, which is why many printer manufacturers are adding protective features such as enclosures and filters. But a new study led by safety science company Underwriters Laboratories (UL) concludes that broader measures need to be taken, in the form of new safety standards.
