3D Printer Emission Monitor Quantifies The Stench
https://hackaday.com/2019/09/03/3d-printer-emission-monitor-quantifies-the-stench/
While we don’t yet know the long-term effects of hanging out around 3D printers, it doesn’t take a in-depth study to figure out that their emissions aren’t healthy. What smells toxic usually is toxic. Still, it’s oh-so-fun to linger and watch prints grow into existence, even when we have hundreds …read more (https://hackaday.com/2019/09/03/3d-printer-emission-monitor-quantifies-the-stench/)
