4 kinds of fillings are suitable
1. Unidirectional filling: the working efficiency of laser marking machine is relatively slow, which is rarely used in processing.
2. Loop filling: it is only used when laser marking fine graphics and fonts, and its working efficiency is similar to bow filling.
3. Two way filling: laser marking efficiency, the effect is good.
4. Arcuate filling: laser marking has the highest efficiency, sometimes there are problems of connecting lines and unevenness. When laser marking fine graphics and fonts, the above problems are not easy to occur, so arcuate filling is the first choice.

The above four filling methods are different, which can be changed according to the actual needs of laser marking. Selecting the corresponding filling method can also improve the efficiency of laser marking. If you do not pursue the details of the laser marking effect, it is recommended to choose bow filling, which can significantly improve the speed of marking. If you want to have both, two-way filling is a good choice.
