Bonjour à tous

l'adhérence au plateau est bonne mais depuis quelques temps les couches de pla se délitent après environ 1 h d'impression ... le début est parfait puis le plastique n'adhère plus correctement : les couches ne sont plus solidaires ... et on constate aussi des filaments très fins d'un point à l'autre du modèle .... avez vous une idée ?

Ultimaker 2+ , pla du constructeur ....

    Bonjour

    merci pour les réponses, j’ai finalement diminué la vitesse d’impression et ça semble aller.... je ne m’explique pas pourquoi subitement les modèles ne s’imprimaient plus correctement... (bobines neuves gris et bleu)

    Buse habituelle ne veut pas dire neuve :) Si elle a prix 15kg dans la tête sans compter si tu as fait un peu d'abrasif, elle se détériore rapidement :)
     

    Après, penses peut être aussi à nettoyer toute la tête c'est à dire : buse + corps de chauffe + vérification du ptfe + isolant teflon voir si il n'y a pas de merdouilles quelques part qui puisse boucher l'entrainement du fil 😉

    Nettoyage méthode atomic dans un 1er temps.

    Après, démonter complètement la tête aussi ça peut être intéressant car on peut passer à côté de quelques choses 😉

      • 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!
          • Thanks

      • 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.
