You can make it accessible.

1. Find "DlgModeler.ui" and "ModelerDialog.py" files in QGIS folder. (That folder depends on which way you installed it).
   By default (in Windows), "DlgModeler.ui" is located in "QGIS_PATH/python/plugins/processing/ui/" and "ModelerDialog.py" is located in "QGIS_PATH/python/plugins/processing/modeler/"
   


2. Open "DlgModeler.ui" in editor (maybe notepad), find "addaction" tags. Add "<addaction name="mActionExportPython"/> and save.


3. Open "ModelerDialog.py" in editor and uncomment the lines below and save it.

#self.mActionExportPython.setIcon(
# QgsApplication.getThemeIcon('/mActionSaveAsPython.svg'))
.
#self.mActionExportPython.triggered.connect(self.exportAsPython)


4. Open QGIS 3.0

EDIT: As @ndawson says (in comments), this method just re-adds the removed "Export as Python Script" button. Exported script has QGIS 2.x syntax and it won't be usable in QGIS 3.x. For further information about QGIS 3.x syntax, visit Processing script template for QGIS3.

  I didn't realized that the syntax of exported file by "Export as Python script" in QGIS 3.0 (in its current form) is uncompatible with QGIS 3.0, because the way to write Processing script has changed. Further information: Processing script template for QGIS3
