New Cooling for the Laser Cutter – Part 1

Last Thursday, Ben and Kevin started experimenting with a proper closed loop cooling system for the laser cutter. This is something we’ve wanted to do for some time, as it’ll make the laser easier to move and less likely to spill coolant all over the floor (again). The big push now is that the existing coolant pump is getting noisy, so it’s an ergonomic consideration 🙂

Most of the parts for this build were sourced from the junk pile, including the reservoir, fan and pump. We bought a cheap ebay radiator and a bunch of plastic fittings.

At this point, we’ve got a few slow drips to chase down, and need to figure out how to enclose the system, but as evidenced in the picture, it cools pretty well. Ben is using a blowtorch on that piece of copper tube (our stand-in laser tube), and it’s cool to the touch immediately after removing the fire.

While we’re waiting on the “good photos” from Garrick, enjoy these two less good photos I snapped of some our members’ handiwork.  As always, we had quite the turnout for this event, with several members bringing friends and family to play along.

A special thanks to Sarah and Jeff for helping make it go off without a hitch, particularly in the processing and emergency procurement of our frosting supply.
