My Tech Fun | The most powerful laser I tested so far: Longer Laser B1 30W @MyTechFun | Uploaded June 2023 | Updated October 2024, 3 hours ago.
The B1 30W by Longer 3D is the most powerful diode laser I tested so far on Mytechfun channel. It has several great solutions too. The main problem with this prototype unit is the air assist system which is too weak.
