Liquide gris qui coince la buse

Recommended Posts

Bonjour,

Il m'est arrivé que du jour au lendemain que le PLA fondu ne pouvait plus sortir de la buse de mon imprimante ultimaker original +.

En essayant de dévisser la buse du bloc en acier j'ai remarqué que celle ci était coincé par une sorte de liquide durci grisâtre.

J'ai d'abord pensé que c'était un peu de PLA qui était passé entre la vis de la buse et le filetage du bloc d'acier mais ça n'a pas fondu quand j'ai réchauffé le bloc d'acier à 200 C°, de plus ce matériaux avait un teint un peu métalique (alors que j'utilise du PLA parfaitement gris "plastique")

Bref je n'ai aucune idée d'où ce plastique un peu métallique peut venir, surtout qu'aucunes autres pièces du feeder ne semble avoir fondu...

A moins que tu aies lubrifié l’intérieur du bowden, ca ne peut être que du filament infiltré et cramé comme dit Zizon.

Tu montes bien les buses à chaud serrage moyen et surtout en vérifiant que les portées buse et bloc soit propre ?

    • "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.
