Emission Of Selected Environmental Exposure From Selective Laser Sintering (SLS) Polyamide Nylon (PA12) 3D Printing Process

Indoor Air Quality (IAQ) is very important to the health and comfort of occupants inside building. The quality of indoor air depends on the air pollutant inside the building. A bad IAQ in workplace will lead to negative impacts to the operators such as dizziness, irritation, headache and others. Add...
