I only open slicer (version 4.11.20200930 ) and paste the following script into the python interactor window:

import math
import numpy as np
import sys
np.set_printoptions(threshold=sys.maxsize)
inputModelFile = "C:\\\Users\\\User\\\Documents\\\Slicer\\\test area.stl"
outputDir = "C:\\\Users\\\User\\\Documents\\\Slicer\\\Tiff"
outputVolumeLabelValue = 255 #contrast?? 255= white
outputVolumeSpacingMm = [0.0635, 0.0635, 0.1] #mm steps/resolution 400dpi =15.748dot/mm =0.0635 
outputVolumeMarginMm = [0, 0, 0] #mm of buffer before/after and around
inputModel = slicer.util.loadModel(inputModelFile)
bounds = np.zeros(6)
inputModel.GetBounds(bounds)
imageData = vtk.vtkImageData()
imageSize= [4724,4724,1]   
imageOrigin = [ bounds[axis*2]-outputVolumeMarginMm[axis] for axis in range(3) ]
imageData.SetDimensions(imageSize)
imageData.AllocateScalars(vtk.VTK_UNSIGNED_CHAR, 1)
imageData.GetPointData().GetScalars().Fill(0)
referenceVolumeNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLScalarVolumeNode")
referenceVolumeNode.SetOrigin(imageOrigin)
referenceVolumeNode.SetSpacing(outputVolumeSpacingMm)
referenceVolumeNode.SetAndObserveImageData(imageData)
referenceVolumeNode.CreateDefaultDisplayNodes()
seg = slicer.mrmlScene.AddNewNodeByClass('vtkMRMLSegmentationNode')
seg.SetReferenceImageGeometryParameterFromVolumeNode(referenceVolumeNode) 
slicer.modules.segmentations.logic().ImportModelToSegmentationNode(inputModel, seg)
seg.CreateBinaryLabelmapRepresentation()
outputLabelmapVolumeNode = slicer.mrmlScene.AddNewNodeByClass('vtkMRMLLabelMapVolumeNode')
slicer.modules.segmentations.logic().ExportVisibleSegmentsToLabelmapNode(seg, outputLabelmapVolumeNode, referenceVolumeNode)
outputLabelmapVolumeArray = (slicer.util.arrayFromVolume(outputLabelmapVolumeNode) * outputVolumeLabelValue).astype('uint8') #voxel array as numpy array ('uint8') 
final=np.invert(outputLabelmapVolumeArray)
finaltest = np.where(final > 100, 0, 1)
pip_install("imageio")
import imageio
for i in range(len(outputLabelmapVolumeArray)):
    imageio.imwrite(f'{outputDir}/image_Page{i:03}_Clr1.tif', final[i])
