First, we varied the layer heights from 0.1 mm to 0.5 mm. As the layer height of each test strip increased, the approximate resistance decreased (see Table 2). Also, the taller the layer height, the lower the resultant quality of the print. We decided to keep the layer height at 0.1 mm so that the header holes of the strips had the best print quality possible (shown in Figure 2), and so that the surface of the strips could be as smooth as possible.

Table 2:

Test Strip Resistance Relative to Print Layer Height

Layer Height	1 cm (Close)	$\sim$ 13.2 (Middle)	$\sim$ 26.4 cm (Ends)
0.1 mm	2.55 k $Ω$	6.1 k $Ω$	11.6 k $Ω$
0.2 mm	3.38 k $Ω$	6.5 k $Ω$	8.66 k $Ω$
0.3 mm	1.27 k $Ω$	5.8 k $Ω$	7.7 k $Ω$
0.5 mm	1.64 k $Ω$	4.06 k $Ω$	6.82 k $Ω$
