“…Low expenses and wide availability of printers render the FDM particularly suitable for the manufacture of cells. Most frequently used filaments are polylactic acid (PLA), [8 , 7 , [14] , [15] , [16] , [17] , [18] , [19] acrylonitrile butadiene styrene (ABS), [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] polypropylene [30 – 32] , and polyesters [33] . Cells manufactured by FDM 3DP involve multitude of functionalities and have found use in a broad range of electrochemical processes and applications, which are summarized in Table 1 .…”
