Why choose a 3D printed traffic barrier?

Traffic barriers are essential elements in real-world construction and roadwork. They provide safety, mark exclusion zones, and help direct vehicles or pedestrians. Including a 3D printed diorama accessory like this barrier adds realism and storytelling possibilities to your scenes.

You can use these barriers to:

• Depict restricted or dangerous areas.

• Mark temporary roadworks or construction sites.

• Cordon off areas in your RC dioramas.

• Enhance the detail of scale city or highway layouts.

By adding just a few barriers, you give your diorama a professional and authentic look.

Scaled dimensions

The design is based on real traffic barriers with dimensions:

• Original size: W: 400 mm / 15.75 in, H: 800 mm / 31.50 in, L: 1100 mm / 43.31 in

The 1:14 scale version measures:

• Width: 28.5 mm / 1.12 in

• Height: 57.1 mm / 2.25 in

• Length: 78.5 mm / 3.09 in

These proportions make it a perfect match for scale model displays and RC construction layouts.

Printing recommendations

This 3D printed traffic barrier has been optimized for straightforward, support-free printing:

• Supports: None required

• Glue: Not necessary

• AMS (Automatic Material System): Not required

Recommended material:

• PLA or other low-shrinkage filaments. PLA provides accuracy, easy printing, and a clean finish.

Suggested slicer settings:

• Filling: 20%

• Fill type: Any (grid, gyroid, cubic)

• Layer height: 0.2 mm recommended

With these settings, the barrier is quick to print and easy to replicate in larger numbers.

Painting and finishing

For maximum realism, paint your 3D printed barrier in traditional red-and-white or orange-and-white safety colors. Acrylic paints are ideal for PLA and can be applied directly after printing.

Adding reflective tape or decals enhances the realism even further, especially if you use the barriers in RC construction dioramas under proper lighting.
