No top and bottom layers?

Can anyone help me with this?How can How can I make a print something like this without top and bottom layers?

The print you've shown is created with a hexagonal infill of relatively low percentage and the slicer has the settings for top and bottom layers set to zero. If you are unable to duplicate this, provide the slicer you use, to better advise location of those settings.
