Three part respirator venturi valve

thingiverse

This valve body breaks down into three components for streamlined printing and enhanced molding capabilities, boosting production efficiency. First, print each of these separate pieces, then sand them to a fine finish before applying a glossy coat of paint. Next, create silicone molds from the painted parts, allowing you to manufacture 3-4 units per hour or more using clear polyurethane or alternative resin materials. For assembly, utilize cyanate-based adhesives like Smoothcast 325, which offers excellent clarity at an affordable price of around $50 per gallon. This approach ensures that your valve body is both visually appealing and easy to clean. Alternatively, consider utilizing UV/laser/resin printing techniques for a smoother finish, minimizing the need for additional finishing steps.
