Teilweise Überextrusion

Recommended Posts

Hallo an alle erstmal.

Hab nen Ultimaker 2 seit zwei Wochen, bin eigentlich recht zufrieden.

Aber das hier macht mir Kopfzerbrechen. Passiert immer auf dem Base Layer.

es wiederholt sich ein Bereich (Flecken) tritt grosse Überextrusion auf (10%) der Druckfläche.

Immer an den gleichen Stellen.

Weiss jemand was die Ursache für dieses Phänomän sein kann?

Verzogene Glasplatte?

Toleranz in dn Führungen?

Hast Du eine Banane in einer der Achsen? Das siehst, wenn Du den Druckkopf (langsam, am besten bei ausgeschaltetem Gerät) von der Mitte her in jede Richtung bewegst und dabei darauf achtest, ob der Abstand zwischen Endblock und Rahmen sich verändert.

Ev. hilft es schon, ein ganz klein wenig mehr Luft zwischen Düse und Glasplatte zu schaffen (aber die Linien müssen immer noch schön zusammen sein, sonst ist es zuviel).

    • "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.
