Probleme mit PVA Stützmaterial

Hallo,

ich möchte mich kurz vorstellen und habe gleich ein erstes Problem.

Meine Name ist Stefan bin 49 Jahre alt komme aus Mannheim und

besitze einen Ultimaker 3

 

Mein Problem ist, dass das Stützmaterial PVA sehr schlecht gedruckt wird. Ich habe es mit dem original

PVA von Ultimaker und von Form Futura ausprobiert. Habe derzeit eine Print Core von Solex 3D mit einer

0,6 Düse eingebaut.

Meine Drucktemperatur ist 215 °C meine Druckplattentemperatur beträgt 60 °C.

 

Ich weiss derzeit nicht weiter und hoffe hier Hilfe zu bekommen.

 

Vielen Dank schon mal im Voraus

 

Grüße aus der Quadratestadt Mannheim

 

Stefan Müller

    Hast du schonmal den BB-Core im rechten Schacht, also dem, der in der Höhe immer geändert wird, der linke steht ja fest, versucht? Der ist extra auf PVA optimiert. Das sind die AA und die Solex

    nicht. PVA hat so seine Eigenheiten. Das nächste ist, hast dein PVA schon getrocknet? Und mit welchen Material willst du

    das kombinieren - ich denke mal PLA, oder? Und welche Geschwindigkeit?

     

    Gruß, Digibike

    Hallo Stefan,

     

    Deine Druckparameter für PVA (Temp. und Geschw.) entsprechen den Standardwerten in Cura, daran dürft's also nicht liegen.

    Was genau klappt denn nicht mit dem PVA-Druck? Schlechte Haftung? "Fransige" Ränder beim PVA (was in gewissem Rahmen durchaus normal sein kann), schlechte Extrusion? "Feeder-Fraß"?

     

    Feuchtigkeit könnte zwar ein Grund sein, da die Luft hier in Mannheim ja gerade nicht sonderlich trocken ist, aber solange das PVA sich trocken und nicht "klebrig" anfühlt oder beim Extrudieren übermäßig "knistert" dürfte das keine große Rolle spielen (hab' letztes Jahr das PVA gut zwei Monate offen am Drucker gehabt und keine Probleme bekommen).

     

    Grüße

    (PS: berufsbedingt kann meine Reaktionszeit auf etwaige Rückfragen etwas länger dauern)

      • 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.
