Additional information

The difference between the two diameters must be at least 0.8 mm.

  • 2025-09-07 (last model before revision: #1608) :
    The minimum value between the two diameters is now set to at least 0.8 mm.
  • If the end fillets option is enabled, the applied fillet radius on the inside and outside of the tube changes from “half the wall thickness minus 0.4 mm” to “half the wall thickness minus 0.1 mm.”

  • The length of the straight sections is equal to the outer diameter of the tube.
  • The arc radius is equal to the outer diameter of the tube.
  • If the end fillet option is enabled, the fillet radius applied to the inside and outside of the tube is equal to half the wall thickness minus 0.1 mm, never exceeding 3 mm.

3D-printable pipe elbows

Pipe elbows make it possible to change the direction of a fluid circuit, whether for air or liquid, while maintaining smooth and controlled flow. 3D-printable, they are suitable for many applications such as DIY projects, ventilation systems, ducts, piping networks, or fluid transfers. Their parametric design allows adjustment of inner and outer diameters, angle, and optional rounding to simplify assembly.

The parametric generation system also makes it possible to create very thick walls relative to the internal diameter, for specific builds — as shown in this elbow model, which perfectly illustrates this robust configuration.

For a very gentle direction change, a low-angle elbow helps maintain smooth and continuous flow. For a sharper turn, a 180° elbow enables a complete U-turn of the flow in a confined space, ideal for compact systems or return lines. These models maintain a smooth internal passage to reduce pressure loss and ensure good hydraulic or airflow efficiency.

Finally, for larger volumes, a large-diameter elbow provides excellent stability and high throughput while keeping a constant wall thickness for greater strength. These 3D-printable elbows combine precision, adaptability, and durability, offering a reliable solution for creating or repairing custom fluid circuits.
