INTRODUCTION
3D printing is increasingly present in research environments, and could pose health risks to users due to air pollution and particulate emissions. We evaluated the nanoparticulate emissions of two different 3D printers, utilizing either fused filament fabrication with polylactic acid, or stereolithography (SLA) with light curing resin.
METHODS
Nanoparticulate emissions were evaluated in two different research environments, both by environmental measurements in the laboratory and by personal sampling.
RESULTS
The SLA printer had higher nanoparticulate emissions, with an average concentration of 4,091 parts/cm, versus 2,203 particles/cm for the fused filament fabrication printer. The collected particulate matter had variable morphology and elemental composition with a preponderance of carbon, sulfur and oxygen, the main byproducts.
DISCUSSION
Our study implies that when considering the health risks of particulate emissions from 3D printing in research laboratories, attention should be given to the materials used and the type of 3D printer.
简介
3D 打印技术在研究环境中越来越普及，由于空气污染和颗粒排放，可能对使用者的健康造成危害。我们评估了两种不同 3D 打印机的纳米颗粒排放情况，分别使用聚乳酸的熔融沉积成型或光固化树脂的立体光固化技术。
方法
通过实验室环境测量和个人采样两种方式，评估纳米颗粒排放情况。
结果
SLA 打印机的纳米颗粒排放量较高，平均浓度为 4091 个/cm³，而熔融沉积成型打印机的浓度为 2203 个/cm³。收集到的颗粒物具有不同的形态和元素组成，主要副产物为碳、硫和氧。
讨论
我们的研究表明，在研究实验室中考虑 3D 打印颗粒排放的健康风险时，应注意所使用的材料和 3D 打印机的类型。
