When Scan orientation positional distance is greater than or equal to D, so each vibration mirror scanning, flue dust does not interfere with other laser scans, together
Sample can also reduce internal stress to a certain extent, obtain optimal effectiveness.Equally, when dividing because sintering cross sectional shape is irregular etc.
Reason cannot ensure that Scan orientation positional distance is all higher than or is equal to D, also will appear the feelings that Scan orientation positional distance is less than D
Condition, then after the completion of same sweep time, section was greater than or equal to the sector scanning to be scanned of D to Scan orientation positional distance simultaneously,
The region to be scanned successively to Scan orientation positional distance less than D is scanned again, it is ensured that waits sweeping in same time sweep section
The scanning effect for retouching region is unaffected, again respectively control laser scanner to other sweep times section region to be scanned into
