Bespannen von PLA


Recommended Posts

Posted · Bespannen von PLA

Hallo Zusammen

Im Rahmen eines Projektes versuche ich ein Flügelgerippe , aus PLA zu drucken und dann zu bespannen.

Der Druck ist nicht das Problem, jedoch das PLA. Ich weiss nicht wo sonst ich diese Frage stellen soll.

Meine Versuche:

Nylon und Spannlack (Problem:Spannlack greift das PLA an).

Klebefolie, die mit einem Heissluftfön gespannt wird (Problem: Hitze verformt das PLA)

Hat jemand von euch Erfahrungen mit dem Bespannen von PLA? Spannlack der kein PLA angreift?

Vielen Dank

    Hi NZehnder ;)

    Keine Ahnung ob es funzt, aber UHU und Holzleim sollen gute Kleber für PLA sein.

    Beides benötigt sehr lange zum Ablüften, also muss Deine Tragfläche auf jeden Fall irgendwo offen und irgendwie gespannt bleiben, zumindest bis der Kleber ausgehärtet ist.

    Dann eignet sich wohl auch Sekundenkleber ganz gut für PLA.

    Aber ob das Im Zusammenspiel mit Spannmaterial gelingt, das kann ich Dir bei keinem Kleber mit Gewissheit sagen, Ausprobieren...

    Kann das PLA vll. irgendwie vor dem Spannlack geschützt werden?

    Bringt es was die Streben vorher mit einem anderen Lack (der nicht angegriffen wird) zu lackieren? Oder diffundiert dann das Lösemittel des Spannlackes durch den "Schutzlack" der PLA-Teile?

      • 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.
