The good news about the UFPs emitted by the few 3d printers in Steele's study was their levels were about the same as cooking indoors.
在斯蒂尔的研究为数不多的3d打印机发出关于超微粒子，好消息是他们的水平是差不多的烹调室内。
Air quality analysis revealed that 3d printers could be characterized as "high emitters" of what are known as "ultra fine particles," or UFPs.
空气质量分析表明，3d打印机可以被描述为“高发射器”的所谓的“超细颗粒”，或超微粒子。
The bad news is that more research is needed on what UFPs, exactly, are emitted by home-scale plastic printers and the impact of UFP emissions in industrial-scale 3d printing environments.
坏消息是，需要更多的研究是什么超微粒子，究竟是由家庭规模的塑料打印机和超微粒排放的工业规模的3d打印环境的影响发射。
