The resin does not need specifically UV light, it is blue sensitive and any shorter wavelength light will make it harden, though the shorter the wavelength...

Im in portland so there is no straight nitrogen available, its all gay.

Nitrogen has a cooling effect on cutting and it requires a lot...

Lol, I think that would be some expensive oxygen with electricity prices....

Some actual parts with he laser cutter, making some grids to attach to my Photogenic studio strobes. These allow me to attach stuff to the standard 7"...

The opening is somewhere around 1mm but the tapers inside are designed to get the gas moving supersonic. They are not cheap either, about $40 a piece....

Not sure, but it cant be much worse than oxy-acetelyene cutting. I think I can use lower pressure, I am still messing around with that stuff....

[QUOTE=JRouche;n2033986]

Yeah, the cutting is exothermic so it basically burns the metal away, but much more controlled than oxy-acet or...

I took a little time to test cutting with 02 tonight. Oh boy, does that work. from 1-2mm/s for 16Ga steel with air to 25-30mm/s using O2. Cuts stainless...

Basically there is just nothing between the molecules and you press it together it just thinks it's all one piece now. No air to create any gaps....

There is cold welding that you do in a vacuum chamber. Pump down to like -9 torr range and then coat a layer of tin on the surfaces and then press together...

Ah, I either didnt know or forgot you were from beaverton.

Acrylic cuts best with co2, it acts like a waveguide for the beam which helps...

Considering the facilities you need to run a big laser space is the least of your issues. Vacuum might work for some things but a log of thing there is...

Lol, that would break the internet. Physics would stop and photons would just stop moving. You can see other outfits I have made in the past on my instagram:...

With a flat table you have gravity working for you. Put the thing on an angle and now you have to have brakes on axis and either counterbalancing or bigger...

Cut a bunch of pieces for a costume from .4mm latex sheet last night: Works well, no burning at all.

Its pretty small, i have not measured, maybe .010" at the surface.

You could put something inside the tube to absorb the beam and keep...

Well, it's basically done. Cut up some parts out of 3/8" acrylic tonight. Im using Lightburn to program the controller, it's a third part lasercutter...

One thing to watch out for is motors can overheat if stop-started often. The high inrush at start eventually builds up as heat in the motors. Softstarters...

I think the system my friend has uses molecular sieves. It has a PLC that switches between the two of them to regenerate.

I'll have to mess...
