This document specifies test methods to determine particle emissions (including ultrafine particles) and specified VOCs (including aldehydes) from Material Extrusion(ME) processes often used in non-industrial environments such as school, homes and office spaces in an Emission Test Chamber (ETC) under specified test conditions. However, these tests may not accurately predict real-world results. This document describes a conditioning method using an ETC with controlled temperature, humidity, air exchange rate, air velocity, and procedures for monitoring, storage, analysis, calculation, and reporting of emission rates. This document is intended to cover a Fused Filament Fabrication (FFF) type desktop 3D printer using thermoplastic materials. The primary purpose of this document is to quantify particle and chemical emission rates emitted from a specific ME type desktop 3D printer which is operated using thermoplastic feedstocks.
