Ultimaker Original - blobs on prints

Recommended Posts

Well this has me puzzled

I think I have ruled out ...

The extruder (inspected/clean...no debris found)

Fans same settings on each

Filament - Used Ultimaker Silver @225C and ColorFabb Orange @ 210C

Retraction set to 4.8mm at 45 mm/sec

Nozzle is clean (atomics show a good, clean nozzle)

Note the same areas with defects. Looks like underextrusion near bottom...then left eye of the robot has some blobs.

What could it be!

Try printing at half speed.  Quality just sky rockets at 20 to 25mm/sec.  And make sure ALL printin gspeeds are the same - none of this "infill faster" stuff.  Fast travel speed is good but slow printing speed.

Hi gr5 and LePaul,

Even a better idea for sure, go for it, but don't change the nozzle -just one thing at a time..

Good Luck.

    • "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.
