Want to use my laser cutter?

Long-long time no see folks!

I had to move out of the city during the Covid shutdowns. I moved my studio down to San Carlos just off the 101. With Noisebridge unavailable to me- I decided to buy a nice ThunderLaser Nova 35 Laser Cutter (among other things).

But it has a lot of idle time- so if anyone is looking for laser time in the mid-peninsula area please message me here or on discord!

Glad to see ya’ll are back open and hope to visit the new location soon.

Hey, couldn’t figure out how to private message, so just posting here.

Would you be willing to test cut a ~15mm diameter circle into 1mm thick polypropylene? I just don’t know if a laser cutter can cut it. A quick google search tells me it can be done, but not sure what power is required.

I’m making a device for biomedical research and just need to cut some holes out of the bottom of a polypropylene well plate (see pic). Would just like to test cut if possible. Will look into finding another laser cutter source if it works. I can’t tell if Noisebridge laser cutter is working (never been there), but will check it out on Sunday.

While I have never personally cut polypropylene- I know it can be done. You’re only doing 1mm thick which will cut very fast with a 100W laser.

In lightburn, you can use the Material Test Generator to find the right settings:

Cool, thanks for the tip! This is exactly what I want to do. If I can cut it with a 40W laser, I’ll just try using one of the cheap 40W units from Amazon.
