Reduce ultra fine particles (UFP), sound intensity and VOCs by placing your 3D printer in a Owlson 3D printer Enclosure

3D printing is not clean. Even PLA will create emissions above the healthy levels*. Usually indoor rooms would assume nano particles up to 2.000-3.000 pt/ccm. In this test case, printing a Benchy boat in PLA for around 2 hours creates a level of app. 175.000 ultra fine particles averaged. By placing your printer inside one the Owlson Enclosure and combine it with an air cleaner, you will reduce this to a level below 25.000 UFPs after some print time. Have a look at the similar result for micro particles ranging from 0.4 micron up to 10 micron (PM1.0-PM10.0). All of our test results was generated by 3D printing the Benchy boat #3DBenchy on a Prusa I3MK2 printer with  Owlson PLA grey filament at our lab facility.

*According to WHO guidelines human should not be exposed to the following particles

10 microgram/m3 annual mean
25 microgram/m3 24-hour mean


20 microgram/m3 annual mean
50 microgram/m3 24-hour mean

The reduction in emission will also be seen for micro particles.

Summarized the following performance can be obtained:


UFP reduction with Owlson 779T Enclosure & Owlson HAC3019 air cleaner by 99.1%

UFP reduction with Owlson 779T Enclosure & Owlson HAC1210 air cleaner by 75.8%

UFP reduction with Owlson 779T Enclosure & Owlson ventilation unit by 77.2%

UFP reduction with Owlson 779T Enclosure & ventilation unit & Owlson HAC1210 air cleaner by 89.9%

Sound Intensity reduction by 22.4%
