Fan mount for Ultimaker 2

Recommended Posts

Posted · Fan mount for Ultimaker 2


First of all, I don't know if there is already a topic somewhere here on the forum with the same discussion. I did some searches but could not find it (which I find strange since I'm not the first one with this question)..

So my question is quite simple. As we all know, the UM2 was designed to fit 2 nozzles. A while ago we all got the news that the second nozzle update will never be coming to the UM2..

That being said, the nozzle is placed to the left and the right fan is further away. This is something that is visible in my prints, the right side of a print tends to warp more due to lack of cooling when printing steep overhangs.

On youmagine I found a few nozzle fan mount upgrades to direct the airflow from the right fan more to the part. Great! But I found quite allot of sollutions. Therefore I want your opinion.. Which one are you using and why? In what material did you print it? I'm thinking of printing it in XT-Copolymer.

Thanks in advance

    don't want to blow my own trumpet but...



    Note the original fan air flows at 0.6m/s and mine is 2.5m/s

    Having the fans horizontal has many benefits. the fans are a lot quieter and it gives them more room for the air to flow.

    I printed mine in XT-CF20, but any higher temp filament will do and recommend using Kapton tape or Nomex heat insulator/reflect paper that @neotko recommends inbetween the nozzle and shroud.

    @Labern other option (nomex so far works just perfect, no discoloration 1-2mm gap between the nozzle and the paper). But I think for really really long term and wooping 1000C heat reflection, Ceramic paper. It's half the price, and there are some of them that are 1mm thickness. I waiting next week to have one to test it, since I don't know how well it will stick with kaptol or how much flexibility has. But 'on paper' :) sounds cheaper/better.

    Well initial test show ghat this ceramic paper can hold quite good. I did trst also with a bic lighter for 3 minutes (in theory around 800-900C) and it went 'greyish' but it doesn't 'burns'. Also I could touch the paper right after and was at toom temperature (thermal camera showed a spike of 200C on a small area but banished just after the lighter was off).

    It costs a full square metter around 30€ (way cheaper than nomex) but isn't exactly paper. It's a 1mm material that fells a bit like cotton and can be broken by hand if pulling strong. It cuts really nicely with scissors and kapton sticks quite ok. I'll do a pla printed part with covering the heat area and check results. One think for sure it deflects the heat better (mainly because it's a 1mm and nomex its more like a sheet of paper of 100grms).

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
