The first L-pbf (SLS) printer I made. The laser control.




The laser from the Chinese Laser cutter





The laser bought from the laserobject. The wire connection and the cooling water connection is completed.





After connection, the test unit for the laser emmission.


After testing, the new laser is installed.




The laser control unit using arduino board is connected with the laser power supply.
The power supply use the very high voltage around 30 KV. It is very dangerous.
The control use the PWM control.


The new laser is installed.
