Nah. Wth a focus zone of a few millimeters, the beam is wonderfully defocused an inch down from the cut and gets blurrier after hitting the etched glass on the inside surface.
However, the Law of Conservation of Perversity ensures the defocused beam will torch whatever precious snippets it may touch, but you already knew that.
Glass readily absorbs 10.64um emf from a co2 laser. So there is virtually no reflection.
The actual amount of absorption of this wavelength allows very precise engraving on glass.
My 10W laser dot is 0.08mm
You probably right, since 10W laser are two lasers allined and 5W (4.5W) is only one.
Iām thinking of using a fine mesh underneath for this. I need to figure out how to ensure that the honeycomb doesnāt become uneven and, in my specific case, guarantee sufficient airflow to extract fumes and create the necessary suction to keep ālooseā parts (objects) attached to the honeycomb. The laser head during cutting is often only 1.5mm from the material face, and sometimes when a loose part lifts from the table and the laser touches or even hits it, it ruins hours of work.
I bought some stainless screen just for this. One honeycomb is steel, so magnets hold it flat.
Thanks for the suggestion, Mike!
What I have in mind is a stainless steel mesh, which I was thinking of placing the honeycomb on top of, but that could cause unevenness.
If I understood your idea, the mesh would be smaller than the total area of āāthe honeycomb and would be āheldā underneath by magnets. To be realistic, almost the entire perimeter of the honeycomb is used for fastening systems and not really a work area. Although, in my specific case, that suction system underneath that I intend to make is precisely so that, in some materials, I can use all the available area.
P.S. This is a topic that has already been resolved, so I donāt feel comfortable continuing to discuss something in this thread that adds absolutely nothing to the purpose of the thread.
I donāt mean to be rude, but letās end this discussion here even if itās beneficial to me.
Not rude, and you are right.
I never mentioned āunderneathā, and did not think of that. That is much better than putting it on top.
If we had ended the thread when it should have been ended, I would have never seen this brilliant suggestion. Not the first Thread to diverge either. Just sayinā¦
