  • Oh yeah that’s a pretty solid benefit right there. I swear the oddest things will block them from cutting. I didn’t even consider the smoke diffusing the beam.

    Like the most powerful laser I’ve used won’t cut through a paper sticker or even the residue but it’ll cut through .75" steel like it’s nothing.

    The optics is a big deal too. On the big ones everything is pretty reasonably sized and they’re still a pain to clean. I can’t imagine what it’s like with those tiny ones. Also, those larger lasers lenses are really commonly coated in thorium and a speck gets on there it’s going to superheat and vaporize a lot of the lense. Pretty damn dangerous to be around lol!


  • CNC laser operator here.

    I don’t know about these lower power lasers so I may be wrong. With the lasers I’ve used (200-2000W), the air/oxygen is used to create a superheated jacket of gas around the laser which allows it to cut a nice smooth edge. It also has the added benefit of blowing away the slag/dross that’s created.

    When we cut more temperature sensitive materials like aluminum and stainless we use nitrogen, which cools the material. This creates a pretty jagged deal with the dross that you gotta sand off but it prevents blowouts and really creates a nice edge if you get the pressure dialed in just right.




  • My bio mom has a cat that’s a compulsive groomer. She’s constantly violently licking herself. It’s so bad she’s lost most of her hair and her skin is all dry and scaley/scabby. Turns into a screaming ball of razors if you don’t let her sit in your lap or acknowledge her sitting in your lap.

    It’s like having an angry scabby nutsack sit in your lap that you aren’t allowed to look at.
