Common problem

FAQ

底层不粘板,模型打不上
检查调平;检查平台是否压着挡光条;检查平台是否凹陷;检查切片参数;检查曝光时间;大模型尽量抽空
底层第一层能粘住,第二层粘不住
尽量减少底层面积,不用斜滑板底,不要设置整版底层,底层采取多个小圆形设置,每个底层不要连在一起
模型打不上
检查支撑是否太细;检查打印速速;检查曝光时间;检查模型摆放角度;检查平台和料槽螺丝松紧;检查离型膜
局部模型打不上
一侧成功一次失败是因为没有调平;四周成功中间不成功是因为抬升距离太低,下降速度太快,适当调整参数
模型质量问题
产生真空拔膜情况的图纸应该侧面开孔处理;使用算法精确的切片软件;尽量使用nfep及更高水平离型膜
模型横截面整齐断裂
设计问题较多,不太容易确定,疑似电机丢步,Z轴稳定性,切片软件,温度湿度多重原因,建议换树脂或者调整树脂配方试一下
模型打印完无法装配
可以降低光强和曝光时间;图纸进行公差补偿;误差补偿(孔改大,柱改小);打磨后处理
打印过程有各种形态垃圾
降低光强,光太强会过度曝光,产生垃圾;检查是否暴露阳光,阳光的紫外线会造成树脂起皮;出现毛刺、片状说明离型膜太松
模型变形问题
处于变形期;树脂不够硬;固化不均匀或不彻底;支撑添加不科学;抽真空后不加支撑或者壁厚太薄
模型像素纹严重
平缓弧面尽可能与平台倾斜一个角度;过度平缓的模型可增加抗锯齿;打磨后处理
树脂保质期
只要是液体,就能使用;长时间在料槽里的树脂会吸潮,打印时间会增加,建议长时间不用倒回瓶子里
模型开裂
模型吸潮;久泡酒精或水;清洗不彻底;曝光不彻底;打印层厚太厚,建议0.03mm-0.05mm;
