Stringing et sous-extrusion

Recommended Posts

Posted · Stringing et sous-extrusion

Bonjour à tous

 

Je suis nouveau dans le monde de l'impression 3D et sur le forum.

Je me tourne vers vous aujourd'hui car j'ai un problème d'impression qui me rend fou...

 

Même si j'arrive à faire des impressions "correctes", j'ai voulu optimiser mes réglages afin de tirer le maximum de mon Anet A8 modifiée.

 

J'ai donc commencé par travailler sur le stringing...mais impossible de trouver les réglages qui vont biens.

 

Je travaille pour le moment sur du PLA et J'ai commencé avec les réglages suivants:

Puis j'ai augmenté la rétraction, la vitesse de rétraction, de déplacement, j'ai augmenté et diminué la température de la buse... etc.

 

Dans tous les cas, des que j'augmente la rétraction pour obtenir une diminution sensible du stringing, je passe en sous extrusion  et ce avant même que le stringing ne disparaisse complétement...

 

Résultats :

 

sans Z-Hop

avec z-Hop de 0.5mm

Merci pour votre aide,

Hello, I'm having a problem resembling stringing in the fill of the part. I do a lot of stringing tests on massive pieces and there's no wire coming out, but when I use it with only one layer and fill, it looks like a spider's web and that's stealing material and leaving the piece fragile. Any suggestion? I'm attaching the profile I'm using and some photos to help me. Big hug to all!

Hello,

 

Stringing is a bit of a mess...

No other choice than making lots of tests.

 

Increase travel speed to 150mm/sec, Increase retraction,  add z up before retraction and level change (0,5mm was a good value for me), and at least try do decrease nozzle temp.

 

in my case, nothing was working. I replaced the nozzle and it is great now

 

hope it will help

 

Alex
