Rachel Spieczny helped Zeepro, the 3D printer manufacturer, raise $348,000 on Kickstarter for their startup, and she's now focusing on another 3D printing initiative she calls Clean Strands. Spieczny says that, while she's a 3D printing booster of long standing, one element of the technology needs more study and investigation – the safety of the process to users. According to Spieczny, the initiative will address a lack of research done on the air quality in businesses, homes and schools where 3D printers are in operation.
