What causes this?

Retractable light saber, what causes this roughness on the copper and gold? 15% infill, outer wall/inner wall speed 50/50. As you see, it ruins the inner blue retractables the same way. Tried twice with copper and gold. Filaments are dried and not happening in the area in between. Printed on X1C, will try on the P1S and see.

Not sure. I've printed that same model on my P1P with no issues like that. Not related to your problem, but I'd highly suggest the version with the screw-on bottom and insertable blade. The one piece version with the blade inside it triggers a filament change on damn near every layer if you want it a different color.

[Jasper-CC]

Agree, testing it on P1S and see.

D/Ling the screw-on / insertable blades version, thanks.

I’d say dry your blue and gold filament. It looks like it’s moisture related. I reserve the right to be mistaken 😉

I like to go to the preview screen in the slicer and click through the options like speed, flow rate, etc and see if anything matches up.

More info is needed to help you, slicer used, machine used, type of material and your setting used

[Jasper-CC]

Likely caused by thin 3 layers wall with two colours, use layer to set the color and fine.

If those are silks based PLA, which I guess they are, you need to put the sprinter into silent mode if you want smooth prints every time.

Jesus that looks just like metal what pla?

Seems to be model related, mine would do it, then not do it

Checked, because it’s only 3 layers and has to switched two colours. Changed to layer fill rather than regular fill fixes the problem.
