Abstract

Indoor Air Quality (IAQ) is very important to the health and comfort of occupants inside building. The quality of indoor air is depends on the air pollutant inside the building. A bad IAQ will lead to a lot of side effect to the occupants such as dizziness, irritation, headache and others. Additive manufacturing is one of the emerging technology, but there are limited studies on emission of SLS printing technology. The design calibration block of SLS printer’s manufacturer is selected to be printed to measure the emission from SLS printing. The powder material use in this research is 100% recycled nylon (PA12) powder material. Data will be collect for four phase of the printing that is from before printing, preparation printing, during printing and after printing. The parameter of carbon monoxide (CO), carbon dioxide (CO2), total volatile organic compound (TVOC), Ozone (O3), Formaldehyde, Particulate Matter (PM), temperature, and relative humidity were measured and compared with the Industrial Code of Practice (ICOP) Dosh 2010. The highest concentration of respirable particulate measured as 0.492 mg/m3 at after printing phase which has exceed the ICOP acceptable limit of 0.15 mg/m3 at the same time the peak value of carbon dioxide CO2 is at preparation for during printing phase 999 ppm is almost exceed the limit of 1000 ppm. The data collected from the emissions of selective laser sintering (SLS) 3D printing by 100% recycled nylon powder suggest that ventilation system of the location should be improve to remove excess pollutant air and fresh air is suggest to supply constantly to the occupant.
