Bottom Skin of Print is having extrusion issues


Recommended Posts

Posted · Bottom Skin of Print is having extrusion issues

The type of printer I use is the Ultimaker and whenever I print a part, the bottom skin that usually has support has extrusion issues. Everything else in the print turns out fine but the bottom skin turns out terrible. I've tried adjusting my Cura print settings to where the bottom skin layer would come out okay. Nothing I tried worked. I have the Printing Temp set to 225, build plate at 60. Print speed set to 30. Here are screen shots of settings I have for the top/bottom layer as well as what my prints look like when they are finished.


Any suggestions?

    Hi @Hpod, you may want to print breakaway support (same material support) with a Z clearance of 1 layer, but the resulting surface will still be rough (and the support will be hard to remove). If you'd like to achieve a bottom surface which is as smooth as the top surface in your pictures, you'll have to print with soluble support (such as PVA). 


    Another possibility might be to design a cilinder (again, with a Z clearance of 1 layer) below the central hole to support it (i.e. designed support), changing your overhang to a bridge, but the surface will still be quite rough and the dimensions of the smaller holes won't be exact. Again, the best result would be to print this part with soluble support.


    Hope this helps.
