Lines at the top layers

[3DReneHub]

Hello, I use cura for the prints I print on my witbox. But the top layers are not very flat. You can see the lines of it. How can I Get the top layers more smooth? I printed this item with PLA, temp 215. Layerheight 0,25 and 3 top layers. Thanks!

Have you considered smoothing the top layer post-printing? Very fine sanding, perhaps with cold water, might create the smooth surface you seek.

Hello Andrew, I have considered it, but that should not be needed. With another printer, the object is looking much better.

Good to hear!

[3DReneHub]

Yes, but the problem still exist, with the Witbox printer

Lower your temperature to the lowest possible you can with the printer.

Use active cooling.

Use a smaller nozzle head.

On what printer do they come out cleaner? The type of machine might suggest some approaches.

The Craftbot gave me a better result. Could it be the slice programm?

[Andrew_247]

Yes, I would say it is. The Craftbot is one heck of a machine - and they provide a slicer that is tailored for their specific hardware. Their whole system is nicely engineered and delivers well and large.
