3D Printed USB Powered Plasma Torch

thingiverse

Proof of concept for a 3D printed plasma torch. USB powered by a DC Electric High Voltage Generator. A plasma torch is a device for generating a directed flow of plasma. Plasma treatments are used to clean and activate the surface of a wide range of materials to make them easier to bond, glue and paint. https://youtu.be/oD7Tvfu5QQg http://www.gaudilabs.ch Q&A: Q: Where did you get the HV converter? Is there a part number or supplier that you could share? A: Got it from ebay, they call it 'NEW DC High Voltage Generator Inverter Electric Ignitor for 18650 Battery K9', around 2-3$ Q: What do you use as gas source? Just air or something special like nitrogen, helium etc? A: I use Argon gas Q: How do you generate the airflow? A: Pressurized Argon gas bottle is connected to the glass tube in the plasma torch by a rubber tube adapter Q: Glass tube is self made, I assume? Just regular laboratory glass tubing heated and drawn? A: Just a regular laboratory glass tubing that I bought in this shape. Big diameter 7mm (100mm long), small diameter 1.6mm (cut to the right length) Q: Did you test the effect on adhesion? A: No, I have not tested this yet.
