Can anyone recommend types of paper (ideally available in colors) that can be cut by laser without leaving any marks (e.g. charring)? Or is it more a function of laser settings (speed, power, lens, etc.) than material? I'm a non-laser user evaluating lasers for possible project. Thanks.
Try 400 on speed and 35 on power for cutting paper.Quote:

Involute is talking about a Co2 laser cutter machine and I don't follow about gases?Quote:

That said, charring on paper is minimal as it cuts so fast and even that noticability varies by colour.
Just find someone with a cutter and test it, they might do it as a favour as it would take under a minute to test.
I don't think you would ever eliminate all charring on materials that burn. It's very slight on wood and cardboard and not noticeable on thin paper. If that's still a problem can you try thin sheets of plastic that melts?
If you don't have a laser, and want to see how much charring occurs stop into a craft store that sells laser cut shapes.
The shield gas idea is interesting. You would need a tank of argon and a regulator. In the end I have no idea if it would help, but it would be interesting to see what happens. Like you find that you can't cut at all...
Hello Involute, this is Nolan from ThunderLaser, hope my suggestion can help you.
1. the laser is fire, it's impossible that can be cut by laser without leaving any marks, but you can control and try to get a good result.
2. if the paper in colors, the marks is not very obvious, you can see some samples from our website.

3. and if you never use the laser cutter, there are many tutorial videos on our website, maybe it's useful to you.
