Düse reinigen

Recommended Posts

Habe einige Zeit mit schwarzen ABS gedruckt und nun für ein Anschauungsobjekt auf rotes PLA gewechselt. Leider sind nun unregelmässige, schwarze Streifen im Objekt.

Wie kann ich effektiv die Düse bzw. den Düsenstock meines UM3 reinigen, damit ich zukünftig einen farblich einwandfreien Druck erhalte?

Auf dem Foto sind leider nicht alle Streifen zu erkennen, wohl aber der an der Spitze des Kegels :(

Danke schon jetzt für eure Hilfe.

Aussen mit einem Lappen im heissen Zustand und ggf. mit einer Messingbürste (kein Stahl!). Beim Einsatz einer Messingbürste bitte zuerst den Silikonring im kalten Zustand entfernen.

Innen am Besten mit dem Printcore Cleaning Assistenten, den Du unter System->Maintenance findest. Dafür kannst Du entweder PLA oder das Ultimaker Cleaning Filament verwenden. Ich würde den Cold Pull empfehlen, der Hot Pull bringt nicht so viel.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
