(A) Illustration of testing setup to measure the particle emission rate from a 3D printer, utilizing an environmental chamber with prescribed dimensions, air exchange and sampling rates following ANSI/CAN/UL 2904. LPM = liters per minute; OPC = optical particle counter; SMPS = scanning mobility particle sizer. (B) Photo of environmental chamber testing setup. Note: The initial particle release measurements were performed inside the chamber to comply with the ANSI/CAN/UL 2904 standard when obtaining the data for use in the CFD modeling. Subsequent measurements for validation of the CFD modeling was performed openly in the cleanroom, as shown in Figure 2.
