Research @ LAESEC

Emerging aerosol sources in occupational environment

3-D Printing Fume


3-D printer has been very popular these days. The filaments used in 3-D printer are mostly thermoplastic, which upon melting will emit VOCs and potential nanoparticles. The focus at LAESEC is low-cost 3-D printer (less than $500) and simulate "garage users" who usually do not have protection such as adequate ventilation. The "garage users" are also creative on using different filaments, from PLA to ABS, from HIPS to nylon. We are even testing more than 10 different types of filaments, including some "wood-polymer" and "weed eater trimmer line".


The experiment is done in an environmental (temperature+relative humidity) controlled chamber. SMPS, APS, and GRIMM is used for particle size measurement and collection. Total and specified VOCs are measured through PID sensor and thermodesorption GC/MS.
