A YouTuber by the name of [1kreature] is doing some excellent research into building his very own 3D printed laser tube.
It all started after he managed to find an extremely high voltage pulse driver. In his video he assures us we should never buy one. He then designed some 3D printed fittings for a clear acrylic tube that allow for pneumatic and electrical connections. Using a hand pump to create the vacuum inside was the most difficult, so he quickly upgraded to a proper industrial vacuum pump.
Apply the vacuum, turn on the pulse driver… and well… see for yourself!
