QIDI X-MAX - Internal Activated Carbon + HEPA Filter

prusaprinters

<h5>Why the filter?<br>&nbsp;</h5><p><i><strong>Filter design will not interfere with internal spool or the moving bed!</strong></i></p><p><i><strong>Apart from significantly cleaning the air inside the printer chamber the filter will also circulate the hot air in the chamber and will help it heat up faster and even.</strong></i></p><p>QIDI X-MAX is very capable printer for it's price, it will print ABS, ASA, PC, PCCF and many other types of filament (with proper extruder and hotend - see the toolhead upgrade <a href="https://www.printables.com/model/229503-qidi-x-max-carriage-upgrade">HERE</a>). ASA and ABS and amazing and affordable materials, suitable for various applications both indoors and outdoors, but… they contain some nasty components that produce nasty odors, VOCs and particles while melted for printing. The activated carbon is great in absorbing smells, fumes and particles. HEPA filter is added to pick up on anything that activated carbon can not or does not catch.</p><p>Both carbon and HEPA containers are easily removed by first removing the main filter body cover. Containers are held together by Neodymium magnets.</p><p>&nbsp;</p><h5>Activated Carbon:</h5><p>There are various types of activated carbon out there, for our purpose it is important to use a specific type that is:</p><ul><li>Steam activated - this is very important as acid activated carbon would quickly rust any steel component of the printer</li><li>Ideally made out of coconut shells</li><li>Made for air and not water purification</li><li>Coarse enough so it doesn't fly around when the fan is turned on</li></ul><p>Active carbon should be replaced after cca 50-60 hours of print time.</p><p>&nbsp;</p><h5>BOM:</h5><figure class="table" style="width:100%;"><table><thead><tr><th>Item</th><th>Qty</th><th>Link</th></tr></thead><tbody><tr><td>60x25 or 60x20mm Fan - Sunon or Noctua</td><td>1</td><td>&nbsp;</td></tr><tr><td>M3 brass heatset inserts</td><td>14</td><td>&nbsp;</td></tr><tr><td>M3x6mm Button-Head Cap Screw (BHCS)</td><td>16</td><td>&nbsp;</td></tr><tr><td>M3x8mm Socket Head Cap Screw (SHCS) - Filter Housing Mount</td><td>2</td><td>&nbsp;</td></tr><tr><td>M3x40mm Socket Head Cap Screw (SHCS) - Fan Mount</td><td>4</td><td>&nbsp;</td></tr><tr><td>Neodymium Magnets - 6 x 3 mm</td><td>8</td><td><a href="https://www.amazon.de/-/en/gp/product/B08F745KY5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1">Amazon</a></td></tr><tr><td>HEPA Filter - 80mm x 42mm x 15mm</td><td>1</td><td><a href="https://www.amazon.de/-/en/gp/product/B07K3TYGX3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1">Amazon</a></td></tr><tr><td>Activated Carbon - Coconut Shells - <strong>Steam activated</strong></td><td>&nbsp;</td><td>&nbsp;</td></tr></tbody></table></figure><p>&nbsp;</p><h5><strong>Printing: - Without any supports!</strong></h5><ul><li>Material: ABS/ASA due to high temperature resistance.&nbsp;</li><li>ALL Parts are printed without any supports!</li><li>Perimeters: 4, solid layers: 5 for both top and bottom, Infill: 20-40%</li><li>All STL's already have correct orientation for print, just import in the slicer of choice.</li></ul><p>&nbsp;</p><h5>Mounting:</h5><p>Stock fans that come with X-MAX have to be removed, in their place we install two back plates to prevent leaving open areas that would cool of the printer chamber. On of the back plates (upper one) is then used to mount the filter on.</p><p>First insert 2 heat inserts into one of the back plates, then screw it on the upper position using m3x6 screws and stock fan holes. After screwing on the bottom back plate, mount the main filter body onto the top back plate.</p><p>Connect the fan to the stock X-MAX fan wires and make sure the fan voltage matches. Make sure the 60mm fan is oriented in a way that it blows air OUT!</p><p>&nbsp;</p><h5><strong>Support and help:</strong></h5><ul><li><i>You can find me on Discord:</i> <strong>elcrni#0940</strong></li><li>Or by DM here on Printables</li><li>If you notice any mistakes in this article or in the models, please do let me know.</li></ul><p>&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/c97bf205-7035-411a-90b0-ec497720decf/01.jpg#%7B%22uuid%22%3A%22e5122123-f091-4757-aa1f-20571c626a7c%22%2C%22w%22%3A1600%2C%22h%22%3A1316%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/039fdf7f-d61d-4930-8c81-f1877c48034c/02.jpg#%7B%22uuid%22%3A%2278fce627-ca4a-4b6a-9bb2-0a0de1db6ef1%22%2C%22w%22%3A1600%2C%22h%22%3A1323%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/129a5469-ba71-4143-871b-b5ddf5b90ec7/x-max-filter.jpg#%7B%22uuid%22%3A%22423d6d41-d36e-4a44-993d-0d17a4c762aa%22%2C%22w%22%3A1563%2C%22h%22%3A1826%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/70288424-793f-49d7-9a95-83537eaf5979/03.jpg#%7B%22uuid%22%3A%22e2466182-4311-432d-8b27-c109429ecc36%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/0e2e4661-ca75-405f-a22c-4656e42a4f92/04.jpg#%7B%22uuid%22%3A%226b5738d0-c11d-4f44-b097-a441982637c9%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/c3850379-d5c9-4e30-8142-267637e0bada/05.jpg#%7B%22uuid%22%3A%22138698b6-4ee8-427e-b16b-b566615b373d%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/e69c4d31-46c6-47b5-ae3c-88ae8c8b831f/06.jpg#%7B%22uuid%22%3A%2251e59bf1-36eb-426c-a36c-fb51d5e7dffb%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/0daac678-71b7-4328-81fe-607074f3c889/07.jpg#%7B%22uuid%22%3A%221fcfb31e-5d94-43c2-8b54-c2e0fc8a540d%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/81e36dec-3bec-4ea0-b058-dd7b99ed8d67/08.jpg#%7B%22uuid%22%3A%227709285e-9e6c-4bec-9215-566f553aa8fb%22%2C%22w%22%3A1600%2C%22h%22%3A1600%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/ff81c376-d3c4-4f3a-b48f-151e4d76dfcc/09.jpg#%7B%22uuid%22%3A%22839005d1-89bb-4eda-bab7-1d2931645784%22%2C%22w%22%3A1600%2C%22h%22%3A1144%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/4dc66411-46de-4385-8086-ed76976fa46e/10.jpg#%7B%22uuid%22%3A%22ab04f595-4eff-40a2-8ee8-1bc85300e859%22%2C%22w%22%3A1600%2C%22h%22%3A1144%7D"></figure><figure class="image"><img src="https://media.printables.com/media/prints/230021/rich_content/18b7be2d-d95d-412c-88c4-d1ca22d77a14/11.jpg#%7B%22uuid%22%3A%222ea9a64f-9275-42a1-af4b-1b8dc12f4fcc%22%2C%22w%22%3A1600%2C%22h%22%3A1183%7D"></figure><p>Proper orientation of the fan, it should blow out!</p>
