Layer delamination - filament change

Recommended Posts

Posted · Layer delamination - filament change

I'm 3D printing on an Ender 3 with Solutech PLA filament (1.75mm) and using an extension in Cura (4.4.0) to pause at a layer. At this point, I'm changing colors (same brand) and finishing out the print with the new color.  My problem is that the second color wants to delaminate from the original and I can essentially pull off all the new layers as a piece because it hasn't "stuck" properly to the original.  Thinking that the pause would result in the original layers to cool, I set the "standby temp" to 210.  Is there some other trick that will give me better adhesion?
