The PDM9 is a mostly 3D printed dart blaster capable of handling a pressure up to 150 Bars (2175 PSI). However, only up to 1200 PSI was tested due to my own safety. The dart blaster accepts a projectile of 9 x 30mm (Diameter x Length), which is 3D printed with the addition of a metal dowel rod for weight. The blaster's solenoid valve is powered by 12V, which can be achieved using 4 x 18650 batteries.
This project requires purchasing non 3D-printed parts, such as the barrel, valve, etc. The list of parts required for purchasing is shown below with links provided:
