Al-Abed, Souhail R. Characterization of VOCs from selected AdMa filaments in terms of chemical content, and nanoparticles/carbon nanotubes. Advanced Materials Role in 3D Printing Applications: Emission Composition, Health Risks, and Sustainability workshop and OECD-WPMN Annual Meeting, ParisF, June 25 - 28, 2024.
Impact/Purpose:
Emission of VOCs and aerosols from thermal degradation of polymers and additives such dyes, metal, and nano plastics are a possible case of health issues to indoor air quality in industry, workplace, schools, and household. These emissions are found to include toxics compounds that may be inhaled during the 3D printing process. The separation and characterization of indoor air needs to be further developed and standardized, especially when there are related to consumer products. Currently, and for the next 3-4 years, the environmental issues related to emissions from 3D printing processes are in the Office of Research and Development’s (ORD) Research Action Plans in two areas within Chemical Safety for Sustainability (CSS). This travel is critical to advance EPA current and future research in nanomateriasl in consumer products and the expansive environmental problems associated with nanoplastics.
Description:
Emission of VOCs and aerosols from thermal degradation of polymers and additives such dyes, metal, and nano plastics are a possible case of health issues to indoor air quality in industry, workplace, schools, and household. These emissions are found to include toxics compounds that may be inhaled during the 3D printing process. We will examine the emissions from fused filament fabrication (FFF) using several common polymer types from multiple manufacturers which use different additives such as metal particles and dyes, metal particles, and carbon nano tubes. This research shows the production of oxidative free radicals and VOCs which may have human toxicological implications due to specific filament additives.
