2 pieces printing problem

[Saithre 0]

Hello everyone.
Can you help me with my problem?

I made an impression of 2 pieces and I could see that the internal sides of these pieces have many damages, on the contrary, their external sides do not have faults.

What is the reason for this?

 

Thanks in advance!

Your nozzle is oozing during the travel to the other object, resulting in those strings.

There are several settings to avoid this, retraction, print temperature too high, .....

 

But when I look on your brim, it also looks not very good. Can you share some more infos, which settings, which material,....

I'm very new at this ?

for this case I used the software Cura 3.4.1, with a configuration recommended by the software.
- Layer Height 1.5
- Infill 15%
- without supports

- Print Temperature 210°

 

the material is PLA / PHA from Colorfabb

Recommended settings sound good for the beginning and looks quite good.

Another question, which nozzle size are you using? It looks like, it is bigger than 0.4, but maybe I am wrong.

 

Have you set the nozzle size in Cura correctly (Line Width)? This should be your nozzle diameter or 7/8 of it.

 

If this is also correct, try to print cooler by 10° C.
