Anyone know the NEJE A40460?

Hi
I have heard of this laser:

It seems that it can engrave on stainless steel:

Stainless steel direct grayscale engraving: Yes
3D hardwood engraving: Yes
Maximum cutting thickness: 20mm

They say the wavelength is 450nm, which make it a visible blue - violet light.

Does anyone have some feedback about its capacities? Thank you.

I’ve seen one person on here who’s marked stainless with a diode…

This laser module can engrave on stainless steel for sure. In order to get better engraving performence, working at 30mm is better, shorter focus lenght means smaller beam size, then you can get higher power desity to engrave esily; For cutting job, working at 55mm is better, longer beam angle is helpful for cutting thicker materials.
