Reci CO2 Laser Head Direct Mount by 3DTOPO Sep 14, 2012


This thing is for mounting a focus lens directly to a Reci W6 laser tube. I think it should work as is on any Reci tube, but it parameterized, so it can easily be adapted for other tubes.

Why would you want to mount the lens directly to the tube? I suppose for most setups it would only be used for testing the laser. For my purposes, I plan on moving the whole laser tube on my large CNC machine, so I should be able to put this to good use (I am not going to steer the beam, I am going to steer the whole tube).

Works great. Very snug fit on both the laser and the laser head. Video of it in action here (it is the green part):

The laser head I am using is this one: lightobject.com/1820mm-Laser-head-w-air-assisted-Ideal-for-K40-machine-P701.aspx

Check this thread for someone with a 150 watt Reci that they may want to get rid of;


I see what you mean. Bummer - the other end (postive anode) looks quite stout in comparison. Hmmm, I wonder what a safe aceeleration value is, and I don't see a way to find out what a max safe value is without first breaking it. I guess I need to find someone with a burnt out tube!

Just to be clear, it is not moving the whole tube that is the issue. It is the narrow glass tube inside the laser tube that will break first. The narrow tube is the one that carries the water (so it's heavy and has a bit of inertia) and is very poorly supported. The end near the output is supported by a single piece of glass tubing (the water outlet), the spring on the end provides no structural support.

Printed at 101% (for PLA shrinkage), use slic3r (0.1 layers, 100% fill) and fits the laser tube and laser head perfectly.

A chunk of plastic connected directly to the output of an 150 watt laser does not seem like a good idea to me. It will heat up - quite a bit.

I think hot plastic mere millimeters away from the output window is going to mess it up.

It is critical that the output window be kept clean. Anytime you have to clean it you risk scratching it and drastically affecting the laser's efficiency You can't replace the output window, once it is damage
d, the whole tube must be replaced.

Well the Laser head I purchased (the black part and the end of the laser) is plastic.

It also has air running through it (air assit) that should keep things cool. That is what the tube hanging down is - and that helps keep the window free of contamanation.
