Perforated metal sign
Perforated metal sign
(OP)
I have a customer that would like a perforated metal sign where various sizes of holes create an image when viewed from a distance. The material is 0.06" stainless steel with over 30,000 holes ranging from 0.05" to 0.375" diameter in a 4' x 8' sheet. Is this even possible with a 10KW laser or will the material warp like crazy? Any suggestions?

Where I work we can cut up to 800 28mm x 19mm rings out of 1800 x 1200 0.5mm 304SS sheet. We dont get much if any curling or warping.
If you ask me to do something, I will do it. There's no need to nag me every 6 months

That would seem to make it almost lacey; I'd almost be more worried that it behaved like actual lace than whether it stayed flat.
If you already know the image, then you can calculate how much material is removed.
TTFN (ta ta for now)
I can do absolutely anything. I'm an expert! https://www.youtube.com/watch?v=BKorP55Aqvg

The customer really wanted aluminum so we ran a test using a 48" square 0.06 aluminum sheet and had very little if any warping. The test pattern had over 15,000 holes ranging in size from 0.050" to 0.239" and some unperforated areas. We used an increment of 6 during cutting, going back and forth over the sheet cutting every 6th hole until finished to minimize localized heating.
