Top Layer Problems

[zer0lady 0]

Hi!

I hope to find some help here, as i get a little frusted i can't solve my "problem"

I use cura to slice an object i like to print.

My object is for example a flat cube with some holes/cut outs. The printer now prints a part on the left side, a part right on the right side and last it prints the middle part of the object. This causes an uneven top layer, because there is a kind of small seam or small gap between the parts. Like the space between the lines changes there because the printer prints close to the last line or more far away from it. How can i solve this? I changed the direction of the pattern in cura,so it looks a little better, but it's not solved.

Any ideas?

My settings:

PLA: 1.75

Temp: 195° (190-205 tested-not successful)

 

Layer Height: 0.2

Flow: 100% (decreasing flow doesnt make it better)

One option is to use the "Ironing" function. From my very limited experience of this function its success will depend on the shapes contained within the top layer. An alternative is to design and print the model with an extra top layer, which has NO holes in it, i.e. just a complete rectangular shape to use your example. Then just cut the layer away with a craft knife where it is covering a hole.

Thank you for your answer!

I read about Ironing but wasn't sure, if i should try. But i will do and give feedback on this.

Cutting with a craft knife might end up with a worse result then the top layer actually is 😉
