  6. 6.根据权利要求5所述的方法,其特征在于,所述步骤(9.3)包括按照下式计算故障比例系数: 故障比例系数=((本次比值/历史比值平均值)/(残迹累积系数/历史残迹累积系数平均值))* (第一稳定时间*第一变化时间/第二稳定时间*第二稳定时间);当该故障比例系数小于预设阈值时,认为3D打印机未出现上述残迹故障或者残迹尚未影响3D打印机的正常;否则提示该3D打印机的残迹影响其加热精度。 6. The method as claimed in claim 5, wherein said step (9.3) comprises a fault is calculated according to the following scale factor: scale factor = failure ((this ratio / historical average ratio) / (Cumulative remnant coefficient / cumulative historical average coefficients of remnants)) * (* a first stabilization time changes the first time / second stabilization time * second stabilization time); when the scaling factor is less than a predetermined fault threshold, the 3D printer that does not appear above vestigial Not affect the normal faults or vestigial 3D printer; otherwise prompt the 3D printer remnants affect the accuracy of heating.
