H2D HEPA and Carbon Air Filter for Laser Cutting · 模型 300362
Don't like inhaling carcinogens? Don't wanna spend $800 on Bambu's air purifier? Neither did I! So I made a gasketed air tight filter that attaches to the back of the H2D for like $30. The entire assembly is designed to be print in place, utilizing the dual printing functionality of the H2D to embed the TPU gaskets. I used 85A TPU but I'm fully confident that it would work with other TPU ratings. This filter works very well, I can't smell anything while laser engraving and cutting. You don't even need to print the rear gasket as its a little overkill. Mounting wise, this enclosure uses the 4*BT3-20 screws that come with the H2D's exhaust adapter. To attach the fan to the enclosure, I have 3 standoffs that accept M4 x 6 x 6 brass heat-set inserts. You can also just snap the standoffs off and glue the fan on with an adhesive like E6000. The filters used are 4" x 4" x 1.2" 3 in HEPA + Carbon Filters that hold up to the same rating as Bambu's filter (0 . 3 microns at 99 . 97% efficiency). I used a generic 120mm x 32mm blower fan powered via USB for the static pressure, it works in conjunction with the fan already present at the exhaust of the printer. Print settings were 15% infill for both the gaskets and the main body. I printed at .2mm layer height with supports enabled (for the filter cavity). The supports came out super clean through the bottom and I had no issues with tolerances. I can't include external links because my member level is too low - but if you need the exact filter and fan you can send me a message. 120mm Blower Model by Russell Gililland If you want the solidworks files, feel free to shoot me a message. Enjoy!
