Twin Blower Anycubic Kossel

thingiverse

Twin Blower Note: I came up with this thing to see how far I could push things... I expect it will work but I don't know if I'll get round to printing this one out. You have been warned. Why? Well, I've tried some cooling solutions, made some of my own and possibly brought the Venturi as a new option to 3D print cooling... My main conclusions are: -The Anycubic Kossel can benefit from upgraded print cooling -The factory nozzle isn't that bad -Upgrading the blower will probably bring the single biggest improvement -Venturi-style cooling does bring a noticeable benefit on top of whatever else your duct does... -...if you get the measurements right. -Venturi fan intake ducts bring a theoretical improvement, but I'd consider that a bonus if incorporated in to a fan guard rather than an must-have Which brings us to the old adage: "There ain't no substitute for cubes" -or- Being able to move more air is always the thing regardless of design / efficiency considerations. There's a limit to how big a fan you can bolt on to this printer without clashing with effector arms, so why not bolt on another fan + duct..? ...because it's probably silly. As silly solutions go I kind-of like this fit of lunacy: -Two fans = more power! -Fan #2 has a much better flow path than the stock location will allow -It all bolts up to the original mounting, hopefully, without getting in the way of anything -As I've gone for a single-sided solution for the previous reason I've attempted to use the Bernoulli / Venturi effects with two flow sources to: i) Up the efficiency further ii) Manage the flow characteristics coming out of the nozzles I don't know if I'll actually try it, but as the design is (possibly) done it's here for interest, or at least giggles. I think I'm done with air-flow experiments for this printer. For myself I'll stick with my Better Blower design on the intake side and Exhaust_Duct.stl (from my Venturi Project thing) on the output side... ...they both use very little filament, are ok with PLA, aren't too horrid to print, don't get in the way, and work.
