High-Efficiency Venturi Fluid & Fertilizer Injector
Optimize your fluid mixing, aeration, or agricultural fertigation setup with this precision-engineered 3D Printable Venturi Fluid Injector. Designed specifically for additive manufacturing, this model incorporates optimized internal fluid dynamics to generate strong vacuum suction at low inlet pressures—without requiring external power or moving mechanical parts.
Key Technical Features:
-
- Standard 3/4″ G (BSPP) Plumbing Ports: Engineered to connect seamlessly to standard garden hoses and water lines.
- Versatile Suction Connection: Includes dedicated suction porting designed for standard G 1/8″ / M10 fittings or direct hose barbs.
- Hydrodynamically Optimized Flow Path: Features a 21° converging inlet cone, a 6.5 mm accelerated throat, and a smooth 7° diverging diffuser to maximize pressure recovery and vacuum efficiency.
- Reinforced Wall Geometry: Built with heavy outer wall thicknesses to handle internal water pressure and prevent layer shear during fitting installation.
Recommended 3D Print Settings
-
- Material: PETG, ABS, or ASA (PETG recommended for chemical resistance and UV exposure).
- Perimeters / Walls: 4–5 walls minimum (critical for pressure-tight, leak-free operation).
- Infill: 30%–50% (Gyroid or Grid pattern).
- Layer Height: 0.16 mm – 0.20mm for smooth thread formation and crisp internal cone angles.
- Support: No support required (print vertically oriented on the inlet base).
