I am surprised too. I worked at a place that had 3 kW CO2 lasers measuring a multitude of this small tube. When people used them for hobby projects they needed several passes to get through 5 mm plywood. The only explanation I can come up with is that those machines focussed from quite a wide beam to a small dot where it hit the material, making them only really suitable for cutting flat sheets (which was indeed the typical application). When used that way they were really fast. This little machine here seems to use a narrow beam right from the tube, keeping the energy focussed all the way.
I wonder if you can use it to cut onyx blades. Apparently onyx blades are supposed to be super sharp but very hard to craft because of how brittle but holding the material at specific angles and laser cutting could work if it will cut it.
There's air pressure coming through the nozzle to keep smoke off of the lens, but it also pushes material through as it cuts. When you don't get through on the first pass, you risk blowing the material around instead of through, and the heat has no where else to go. That's why the flame.
That would not work since it's not really cutting, it's burning. So the oxygen is needed. Only materials that vaporize/desintegrate purely by temperature could be "cut" that way.
What if you just had a generator between TWO trees, putting some rod around 4m high on the trees It seems like the wind would overcome a lot of resistance (ignore the branches, capture the lower movement high torque swaying?
You confuse me. First you show how you can move the cutting area to align with the material and thus minimize waste. Then go on to perform test cuts smack dab in the middle of the sheet goods. Why not cut with minimal waste and maximize the useful area of sheet goods by staying close to the edges?
Thanks CCC
Very cool! 👍🏻
My laser cutter can't compete! It would have to do 100 passes to cut what yours can in a single pass 😛
The detailed review is much appreciated!

That boaty project sounds interesting but very ambitious. I'm curious if it can be done.
Can you use rubbing achohol for better thermal control than water?
I wonder if it would be worth it to fill the chamber with nitrogen to prevent the combustion of wood or carboard or the oxydation of metal…

Dejavu? Wasn't this video published previously? rip
Why do you keep reposting your video
