- Test engraving stainless steel using the xTool D1 Pro infrared laser head. I engraved using 4 different tool heights to determine the effect on the engraving.

Nice bit of equipment.
Lots of possibilities . Great Video
Hello Mick,
Thats a cool bit of kit... It works really well. Happy New Year to you. I hope 2024 is a good one for you.
Take care.
Paul,,
That is a very cool tool and it works really well
Thanks Mick's Workshop.
What I would like to know is, did the laser vaporise stainless steel? If so, there should be a corresponding engraving depth of 0 mm to 3 mm depending on the focus position. The near black colour seems to result from a thermal oxide reaction. Of course, the oxygen bound with it increases the weight of the sample. An interesting question is therefore, at what focal distance can a calibration seal, for example, be produced in a stainless steel substrate without any change in weight? A possible application would be stainless steel calibration weights which, together with a laser QR code, would produce a digital calibration certificate.

You can feel a slight depth with a fingernail, however it is nowhere near the height adjustment I made, I will put it under the microscope and see what's there. I do not have the equipment to determine weight differences. My interest in it is being able to mark parts such that they can be read by a human. I suspect that for the application you are interested in that something better than a hobbiest machine would be needed.
A couple of questions.
Is the black a permanent feature of the stainless or can it be scrubbed/buffed off?
Is there any change of depth between 0 and 3mm?
What kind of stainless are you working with & have you tried any different kinds of stainless?
Excellent questions! The black does not rub off, at least with scotchbrite. Nor does heat affect it, up to approx 600 degrees (I didn't go beyond that). There isn't a noticeable depth difference, although I didn't attempt to measure it. I'll put it under the microscope and see if I can tell the difference. I'm sorry but I don't know what grade of stainless it is, it came from the scrap yard. It would have been used in an industrial setting.
