POP! Goes The Hydrogen Howitzer
In an innovative foray into 3D printing, Flasutie has gone beyond mere aesthetic models to create a fully functional 3D-printed howitzer that not only looks impressive but launches shells powered by oxyhydrogen, or HHO. The key to this project lies in utilizing the hydrogen produced through electrolysis of water for a truly explosive effect without compromising safety. To achieve this, Flasutie opted for 30 mm projectiles made of thin-walled PLA, ensuring they rupture harmlessly upon impact, even when held in hand. The impact fuze, featuring a piezoelectric spark mechanism encased in a soft TPU tip, adds to the overall safety by ensuring reliable detonation upon impact.
The miniature howitzer itself is a marvel of 3D printing, mirroring a downsized military fantasy. Almost entirely 3D printed, it incorporates an interrupted thread breech-locking mechanism and a recoil-absorbing system inspired by real artillery. The functional breechblock goes beyond mere aesthetics, operating under spring power to snap open and eject spent cartridges, providing a realistic touch to the model. The entire build, including a captivating loading sequence and demonstrations of cardboard-defeating “armor-piercing” (AP) and high-explosive (HE) shells, can be witnessed in a video shared by Flasutie.
This project showcases the potential of 3D printing in creating not just static military models but functional and safe replicas of artillery pieces, bringing a unique blend of realism and creativity to the DIY community. Flasutie’s careful consideration of safety measures, such as the choice of material and impact fuze design, underscores the responsible approach towards crafting explosive elements for recreational purposes. The result is a visually stunning and engaging miniature howitzer that captures the imagination of military enthusiasts and 3D printing aficionados alike.
