Sottoestrusione Ultimaker 2

Recommended Posts

Ciao a tutti,

riscontro un problema comune a molti, la sottoestrusione del materiale.

Possiedo la stampante da tre settimane. ho stampato molto in PLA per poi passare a Colorfabb XT bianco, che é un materiale più rigido e necessita di temperature elevate dai 240° fino ai 250°.

Da un paio di giorni la stampante non riesce più a estrudere la quantità di materiale necessaria per delle stampe decenti. Ho, nell'ordine:

 

  1. pulito il noozle col l'Athomic method diverse volte.
  2. Pulito il noozle con un esattore da 0.3 mm (un piccolissimo fil di ferro)
  3. Smontato e rimontato l'estrusore abbassandone la pressione quasi al minimo (come consigliato in più parti su questo forum).

Nulla cambia. Qualcuno ha già affrontato questo problema? Come ne é uscito?

sospetto che il PTFE coupler possa essere deformato o che ci possa essere del materiale buciato all'interno.

Grazie a tutti

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
