Is this under extrusion??

Recommended Posts

IMO the maybe top layer is not thick enough, and it could be some under extrusion in the body of the print, hard to see from the photo.

you should post all of your settings to help with diagnosis, also what extruder feeder are you using - the standard one ?

I can see in the walls of your print some underextrusion here and there. The top is hard to tell what the issue is - it looks like you only have 2 top layers so I would thicken that. Please post:

print speed, nozzle temp, layer height.

For example for .2mm layers you don't want to go faster than these speeds:

20mm/sec at 200C

30mm/sec at 210C

40mm/sec at 225C

50mm/sec at 240C

    • "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.
