What is coing on here?

Recommended Posts

to help you we will need more information

what is :- your printer I assume an Ultimaker ?, materiel, head temperature, speed etc etc

 

Ultimaker 2+,pla and normal stock settings. This "pattern" gets worse rhe higher the print.

well to me it looks like too much materiel is being printed, could be due to temperature being too high - you could try lowering by 5-10 degrees

also check flow rate of the extruder feeder its rare to need other than 100% especially for a standard PLA print

what nozzle size are you using - looks like a large one but hard to guess

0.4mm nozzle. The feedrate i haven't messed around with. I will check. Thanks for the tips.

It looks like you are simply trying to print too fast. Is this in spiralize mode maybe? Spiralize mode is bizarre and has special issues which I will explain if you used that.

Basically you are printing too fast I think where the pressure is building up too much and occasionally plastic squirts out the side of where it was supposed to print. Setting flow to > 100% can also cause this.

I would go into cura and display ALL speed settigns including infill and set them all to 30mm/sec just to see if that helps. or in the tune menu while printing cut the speed down to 25% for a few layers to see if that improves the quality.

Is it possible that Cura though you had a 0.8mm nozzle even though you used a 0.4? That would also explain why the pressure was so high.

Lowering temp can also help (more viscous so less likely to spurt out sideways) but doesn't solve the underlying problem of too much pressure in the nozzle.

    • "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.
