Programmed fiber spacing (s, mm), printing speed (F, mm/min), and operating pressure (P, psi) are specified in the Python code to print 0° and 90° PCL layers. One 0° and one 90° layer are considered to be a complete grid with square pores. Pore size (dp, mm) and fiber diameter (df, mm) can be measured using optical microscopy and later used to calculate the experimental fiber spacing to compare to its corresponding programmed value (s).
