Peopoly Moai Air Handler (smell reduction/removal)
Description
This is an air handler/smell elimination strategy for the Peopoly Moai that assumes you've already added a chamber heater with a 12 V power supply. See the following for more details: https://www.thingiverse.com/thing:3326032 First and foremost you'll want to seal around the edges of the door of the unit with medium window seals (as shown in the images), you can find them at home depot or online, just be sure to use the foam kind without any surface texture. After you've sealed the top, right, and bottom sections of the door you can reduce the amount of exposed gap on the left side of the door by adding a few strips of electrical tape (see images). After you've finished sealing the unit you should notice a pretty big improvement to the amount of smell the printer gives off but it won't be completely gone. The filter here uses HEPA filters to help protect the resin in the vat (reduces the particles per cubic foot inside the chamber) and active carbon to remove volatile organics (that nasty smell). You'll want to use metal mesh in addition to the printed plastic grates to keep the active carbon in place. While the parts do fit pretty snuggly together it would be a good idea to secure the prints together with 4 x M3x8mm (5 mm works too) screws and 4 x m3 nuts.From top to bottom you should have parts in the following order: 1) Hepa mount 2) Hepa filter: https://www.amazon.com/gp/product/B01I2QUCOM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 3) Grate 4) Metal Mesh: Woven Wire 60 Mesh 12"X 24" 30cm X60cm x0.25mm Papermaking 304L Stainless Steel 39% Open Area 5) Carbon holder filled with active carbon: https://www.amazon.com/gp/product/B0002566WY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 6) Metal Mesh (the grate below this is embedded in the carbon holder) 7) Fan holder (don't fill the empty space here it's for air flow) 8) 2 x Fans (be sure to orient them so they pull air through the assembly, not push): https://www.amazon.com/gp/product/B074ZF7Z66/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 9) Fan Grate (optional) After printing You'll need to solder the fans together and then power them with 12 V. I piggy backed on the plug used for the heater I previously installed. Be careful not to reverse bias these fans.
