improving print quality, any help/experience?

Recommended Posts

Posted · improving print quality, any help/experience?

I'm trying to improve the print quality one my ultimaker, you can see the tiny blobs on there.

 


  • too much filament = correct diameter?
    to hot currently 200°C ?

 

Also the top extrusion is very bad, it ruined the piece...

Using Cura 10.9 an mac.

Mendelworld PLA filament "3mm"

While I'm no expert, I think there are a variety of things that can cause this. Things I would be looking at:

 


  • Size of filament setting matching the actual size
    packing density
    minimum layer time
    minimum feed rate
    Fan on or off
    speed of printing
    layer size. Looks like pretty big layers.

It's definitely bad cheap filament, the red filament delivered with the ultimaker does not show these blobs.

Measuring the filament it varied from 2,76mm till 2,92mm.

So I guess this topic should really be in the cura section.. :roll:
