Print quality question (photo)

I printed this using BBL Silk using the BBL settings for that filament on my P2S. I do pretty good with most of my projects, but I’m ignorant about quality settings. There must be a half dozen options under the heading of sparse infill for example. As you can see, I have sort of a quilted texture. Any suggestions will be appreciated.

there is a lot wrong in the picture and i would want to say machine calibration but you mentioned it is a P2S so i assume you did the calibration recently as the machine is brand new.

i see temperature fluctuation and a whole lot of z banding so here is what i can suggest:
1 - find a better stable table with lot less shaking, and re run the machine full calibration.
2 - keep the machine chamber temp stable, if its more than 3 degrees in less than 5 minutes then its not optimal.
3 - reduce print speeds, especially the outer wall speed, the slower the cleaner the finish quality.
4 - do filament temperature tower test, when you see the filament is more shiny at certain temp it means its good (not all cases but you can go from there)

also note silk filament tends to make layer lines more visible then normal filament, so print defects will show more.

What infill pattern and % are you using ?

Oh wow! I’m in trouble because it will be awhile before I can come up with a more stable table. It’s currently sitting on a counter that’s bolted to the wall.

I don’t know how to affect chamber temp stability. How would I do that and why isn’t it stable already?

Reduce print speeds. That one I can do.

I’ve never done a tower test. Maybe that’s an AMS thing and I don’t have one. I’ll google to find out how.

Thanks for the response and the advice.

PS: I wonder how you can see temp fluctuations and z banding (whatever that is).

Top surface pattern: Monotonic line

Bottom surface pattern: Monotonic

Internal solid infill pattern: Rectilinear

Sparse infill pattern: Grid with 15% density

Have you calibrated the filament for pressure advance and flow ratio? You may want to increase the number of walls if you are just using two which is the default.

I couldn’t find a setting for Pressure Advance. I did find a flow ratio but no way to calibrate it. Will try 3 walls. Thanks

That quilted texture is usually caused by infill pattern and infill density showing through the top layers. Try increasing top surface layers, slightly raising infill density, or switching to a less “patterned” infill (like gyroid). Slowing top-layer speed and enabling ironing can also help smooth the surface.

Thanks

Thanks for the response. I did two things: Switched from the silk to flat black (wasn’t going to use the silk in my final print anyhow), added a third wall. Problem solved.

For future reference:

Duh! I should’ve dug deeper. I was thinking that calibration was all or none. Thanks much!
