I got some 304 stainless about 25 Gauge (0.5mm) Thickness and it worps. What is best to not worp?
Don’t get it so hot… not trying to be funny… when you get a result and change thickness it changes results…
To get colors I have to put some power into it and it usually warps thinner stainless.
I’ve had to use hold downs to mark some types of stainless and keep it from warping.
I’ll be watching in case you figure out something…
I guess conductive paste and a heat sink might make annealing for color almost impossible. It would be interesting to see if cutting / engraving was still possible.
One of the issues I found when trying to get colors out of stainless…
You have to generate lots of heat, but not enough to remove any material…
If the stainless isn’t the same type/thickness you tested on, it will probably have different results…
Even my 7"square engravings have warp issues…
Hello @Nuchie
You didn’t mention what laser, but if it is a MOPA fiber, we have a lot of tests and parameters on stainless business cards on the Laser Master Academy. And yes, what is mentioned above, it is difficult to get color on a thin piece of SS without warping. And as mentioned above, changing from one ss product to another changes everything.
I even milled out an aluminum jig to hold the cards flat and absorb heat, maybe helped a little but in the end just takes a lot of testing.
