It’s looking more and more certain that 3D printing has a serious safety problem.

 .

Though largely overlooked in the tech press, the problem is pervasive and could impact millions of students, patients, and employees who work in non-industrial settings that lack controlled environments. That’s according to a two-year study by UL Chemical Safety and Georgia Institute of Technology, which shows that 3D printers emit airborne nanoparticles and volatile organic compounds that can cause cardiovascular and pulmonary issues.

 .

The UL/Georgia Tech study details the alarming presence of more than 200 volatile compounds that are detected in environments where a 3D printer is in use, including known irritants and carcinogens. Even supposedly safe 3D printers equipped with HEPA filters aren’t immune. According to the report, HEPA-equipped machines don’t solve the problem of emissions and may even amplify it. Millions of people use 3D printers today. School 3D printing use alone has […]
