The Filament is Bambu Labs Silk PLA, Copper color.
Bambu labs Silk pla settings (and temperature of 230*). I have tried slow down the speed, changed cooling, changed temperature, tried both cold plate and smooth pei plate - but all of the changes makes it worse. I have also made the flow calibration in Bambu studio.
It is only on the bottom, the rest of the print is smooth and perfect.
I hope that someone can help me with what is going on with my print, and what I can do to solve the issue.
I am pretty sure that there’s nothing wrong with the nozzle, I have printed with normal pla afterwards with no problems. I only print with basic and matte pla, and now silk pla, no abrasive filaments.
The print is perfect besides the bottom, If it was a humidity problem, wouldn’t it be the entire print that had problems?
With other filaments than bambu, this issue is caused by order of walls for me. I did inner outer and it fixed the issue with my geetech, however this bambu labs silk pla I cannot get this to go away. It is so incredibly thick and viscous I had to turn the K factor and flow way down, it barely extrudes from the nozzle. I found doing outer inner causes the nice outer wall so sag when the new hot filament comes in and heats up that outer wall it causes more sagging.
I don’t know why but the bambu silk I have is just un workable, silk from two other brands are just fine. Here is what my bambu silk does with ripples: Take a look inside the cavity next to the eye, but it is all over the model on the blue / red multicolor. the model on the right is geetech.
