Some gears and testing for laser-ablating and -marking ...

... my latest (semi-comercial) project is a fiber-laser armed galvo-scanner used for "local ablating" of metal surfaces.

The core project isn't open, but I can show some images and videos of the common parts ...


- for a fast provisoric fixation of the fiber-laser head -- construction of a "3D-LOM-part" in Corel and export as HPGL:

- lasercutting the LOM-slices from ply-wood with a blue 3,5W-diode-module:

- assembled/stacked the slices and inserted holder for the collimator-head:

- mounted galvo-head:

... tested stripping black paint (development for cleaning metal surfaces):

The result: - on the left a black tile -- on the right the black painted aluminum sheet (Dibond)

what kind of laser wavelengths power....

... this was done with modulated CW-fiberlasers - 85Watts max power in the first post and 60Watts in the second, modulated with up to 500kHz, spot sizes around 30 microns ...

Hope to get a pulsed fiberlaser soon, with 20Watts averaged and 80 Kilowatts peak power -- should bite a bit more "agressive" in the material ;)

Viktor

... actually assembling a more "professional" looking marking laser for an exhibition on saturday -- will post some more images and videos of the results later on ...

Beautiful work !

... thanks! - here a first image of the booth ;)

Very cool build, Viktor! That would be a fun tool to have around.

... yes, some others thinks the same ;)
