The data set contains the details on the thermal degradation that takes place during 3D printing of six commercially-available 3D printer filaments containing either carbon nanotubes or metal particle additives. Volatile organic compound (VOC) emissions are measured and used to develop reaction mechanisms. This dataset is associated with the following publication: Potter, P.M., S.R. Al-Abed, F. Hasan, and S.M. Lomnicki. Influence of polymer additives on gas-phase emissions from 3D printer filaments. CHEMOSPHERE. Elsevier Science Ltd, New York, NY, USA, 279: 138543, (2021).

**Alpha Version Data** (has undergone several rounds of internal review from the Moore Institute and is ready for external review) This mock dataset is part of the [Microplastics Data Portal](https://github.com/Moore-Institute-4-Plastic-Pollution-Res/Microplastic_Data_Portal) and is intended to eventually serve as the data shared by state-accredited labs for microplastics in drinking water. It was created by discussions with domain experts. Data comes with a template with mock data entry and a rules file that can be used to validate the data using the [Data Validation Portal](https://wincowger.shinyapps.io/validate/).
