Factor	Speed of the stepper motor	Moving speed of the nozzle	Height from the nozzle to the platform
^a	1.60	1.12	1.07
^a	0.88	0.96	0.91
^a	0.46	0.86	0.96
^b	1.14	0.26	0.16

^a, , represent the average diameter of the printed fibers corresponding to the number i level of various factors (). ^b represents the range of the average of absolute value of difference.
