Trace des buses à la fin de l'impression


Recommended Posts

Posted (edited) · Trace des buses à la fin de l'impression



Après l'impression assez longue d'un dragon en PLA, j'ai des imperfections sur le modèle et je souhaiterais vos avis pour corriger cela.


J'ai 2 types d'imperfections :

- La trace des buses sur les parties supérieures des impressions (ici la patte du dragon), c'est très moche et c'est très présent sur des impressions de type litophanie par exemple. Je n'ai pas encore compris si on pouvait le corriger

- Sur cette impression spécifiquement, j'ai des gros bourrelets sur des légers porte-à-faux (alors que le torture test associé m'a montré que je pouvais aller jusqu'à 60° assez facilement). La vitesse d'impression des murs externes est de 22mm/s, est-ce que c'est cohérent de considérer que tout peut venir une température d'impression trop chaude (J'ai laissé la T par défaut de 210, au lieu de mettre 195) ?


Merci pour vos retours,

    Je serai tenté de dire que ces problèmes sont dus principalement aux conditions climatiques actuelles : il fait plus chaud.
    Du coup, les filaments comme le PLA se comportent ... différemment.

    Essaye d'imprimer deux tronçons en baissant ta température à 190° (oui, 190°).

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
