TPU Flexible Pipe Coupling Generator

Parametric Flexible Pipe Coupling (Supportless)

Connect pipes of equal or varying diameters effortlessly with this fully customizable, watertight flexible coupling. Designed to be secured with standard single-screw hose clamps, this model features mathematically calculated 45-degree chamfered grooves, ensuring a 100% support-free printing experience.

Customization via Built-in Configurator

Using the portal's built-in configurator, you have total control over the model's geometry to fit your exact application. You can easily adjust:

- Inner diameters (top and bottom) to create straight connections or custom reducers. - Total length and wall thickness of the coupling. - Clamp groove dimensions , including width, inset depth, and distance from the edge. - Resolution for a smoother or lower-poly surface finish. Recommended Print Settings (Watertight TPU)

To ensure a completely leak-proof and durable part, print using a flexible filament (e.g., TPU 95A or softer) and apply these specific slicer settings:

- Wall Loops/Perimeters: 3 to 4 walls minimum. Thick walls are the most critical factor for preventing water permeation. - Top/Bottom Shells: 5+ layers to ensure solid caps. - Infill: 100% (or 99% aligned rectilinear) to eliminate internal voids where water could travel. - Flow Rate (Extrusion Multiplier): 105% to 110%. Over-extruding slightly forces material into micro-gaps for a perfect seal. - Layer Height: 0.16mm to 0.20mm for optimal layer fusion. - Seam Position: Aligned on the outer perimeter, strictly away from the internal sealing surfaces. - Cooling Fan: Reduce speed (or turn off) to maximize layer-to-layer bonding.
