I use eSUN (Silk) PLA filament daily and I've never had an issue. I use the parameters suggested by the manufacturer:
- nozzle temperature: 210 °C
- bed temperature: 60 °C (with purple glue)
The extrusions are perfects (the printing itself may be improved, but here I'm talking about the extrusion) even if it runs for 20h+.
Instead with the Silk Rainbow PLA filament, after few hours the extruder is clogged. No more extrusion. I have to stop the printing (and waste all) preheat the extruder, remove the nozzle and extract the filament. Then, feeding another kind of PLA I'm able to recover the functionality.
This happens ONLY with this specific filament!
I tried to increase the nozzle temperature up to 220 °C. It lasted maybe one hour longer but eventually failed again.
The filament is stored inside a dryer that is on during printing. What can cause such a behavior? I have a Dremel 3D45.
Here some pictures. Some parts are broken because I had already thrown it away. The bottom layer is quite good:

Details of the infill and support structures:
Weird enough both the comment and the answer suggest to lower the temperature but here the answer I received from the manufacturer:
You can adjust the printing temperature to 230 °C higher, and then adjust the printing speed to 40 mm/s slower. The plug is generally caused by bad material fluidity, the temperature is set higher, you can increase the fluidity.
