Fanduct Delta Printer by Junior_Designs

Last crawled date: 3 years, 1 month ago

This is a fanduct for Delta Printers, it is compact yet still gets enough airflow to the printing area. All of the designs are for the volcano hotend. As I bought alu parts for my printer to convert all plastic molded parts I came to a hold when I didn't find a compact fanduct that would be easy to mount on the alu parts without getting in the way of the travelling area. I still wanted or atleast was trying to find a fanduct that would blow air around 360° so I came up with my own design. As I use a BLTouch I made a copy with the appropriate mount for it as wel. (One that can be adjusted and one that can't)
There are 3 designs :
-360° fanduct with regular 404010mm fan
-360° fanduct with 404010mm turbo fan
-Fang fanduct with 404010mm turbo fan
Best use Noctua Fans for the regular fanducts, for the turbo fan I used is this one : https://www.aliexpress.com/item/Gdstime-40mm-x-40mm-x-10mm-4cm-DC-12V-2Pin-Brushless-Turbo-Blower-Fan-For-3D/32800602260.html?spm=2114.01010208.3.84.0m912B&ws_ab_test=searchweb0_0,searchweb201602_5_10152_10065_10151_10068_436_10136_10137_10157_10060_10138_10155_10062_10156_10154_10056_10055_10054_10059_10099_10103_10102_10096_10147_10052_10053_10142_10107_10050_10051_10084_10083_10080_10082_10081_10177_10110_10111_10112_10113_10114_10181_10183_10182_10185_10078_10079_10073_10070_10123,searchweb201603_2,ppcSwitch_5&btsid=c33daa72-ec75-4b4a-b957-a20736f3d14f&algo_expid=91aec55e-e0d7-4015-ad02-891773214216-11&algo_pvid=91aec55e-e0d7-4015-ad02-891773214216
The bridges of the part will need supports, however DO NOT USE supports inside the fanduct. You won't be able to get them cleaned up and the fanduct won't be effective anymore then.
The Adjustable BLTouch Mounts work with springs, for the Turbofan I used one big spring and a long M3 Bolt. The M3 Bolt head goes in the slot between the pillars for the BLTouch mount with the threads facing up, the spring goes on the M3 Bolt. Then slide the mount on the bolt and put a nut on top to keep it in place and to adjust height. Pictures on how it's assembled will follow shortly once I have mine all set up.
Little sidenote : I suggest you slow down your printing speed and make sure to either lower extruding temperature a bit or decent part cooling. The fanduct has small surfaces to print in it and not having any cooling, printing to fast or extruding temperature to hot might result in the small surfaces not sticking well and they will end up draging around with the hotend instead of actually sticking together. (This was a lesson I learned after trying a few times)
The Fan Intake is mainly used to create more air suction for the turbo fan. As I noticed it increases a lot of the air comming out of the fanduct compared to without the fan intake.
I print all my printer parts with 40% infill because my printed is in a heated enclosure, therefore I want as much strenght in my parts as possible. But I tested it with 10% and it works just fine to.
