由于层间间隔时间短，热积累现象显著，扫描第三层时，最高温度要显著大于扫描第一层时的最高温度。但第三层相比第二层的温度增加要显著小于第二层相比于第一层的温度增加，即最高温度会随着打印层数的增加而趋于一个稳定的数值。

Due to the short interval time between layers, the phenomenon of heat accumulation is significant. The maximum temperature of the third layer is significantly higher than that of the first layer. However, the temperature increase of the third layer compared with the second layer is significantly less than that of the second layer compared with the first layer, that is, the maximum temperature will tend to a stable value with the increase of the number of printing layers.
