With the infill function you are able to add a lattice to the print. You can select on the diameter of the lattice and the cell size.

If you leave the checkbox ‘join infill in 1 mesh’ checked (recommended) then the infill is joined into 1 mesh. If you uncheck it then each part of the lattice will be added as an individual beam. This means you are able to edit the parts individually. When in transparent view mode you can select (and delete) the lattice inside the object.
