Rocket League Dominus - HIGH DEF

🚗 Rocket League Dominus – HIGH DEF

This is a high-definition Rocket League Dominus rebuilt specifically for clean multi-color printing and reliable results on consumer FDM printers.

The original Sketchfab model looked great, but like many game assets, it wasn’t printable out of the box. This version focuses on printability, clean slicing, and strong visual results, without sacrificing detail.

🎯 Project Goal

The goal of this project was to create a display-quality Dominus that:

• Prints cleanly in multiple colors
• Maintains sharp, recognizable Rocket League proportions
• Works well with AMS and support interface materials
• Is approachable even for long, multi-plate prints

The original Sketchfab model was non-manifold, meaning it required significant cleanup before it could be reliably sliced or printed.

🔧 Model Modifications & Print Prep

To prepare the Dominus for 3D printing, the following changes were made:

• Converted the entire model to manifold geometry
• Removed or reinforced features that were too thin to print reliably
• Closed hollow details such as exhaust openings
• Increased mesh resolution and smoothed surfaces
• Separated select components (boosters, taillights, brush guard, etc.) so they can be printed flat on the build plate for better surface finish
• Cleaned up geometry to improve color boundary detection in the slicer

These changes result in cleaner color separation and more predictable prints, especially on multi-color builds.

🖨 Recommended Print Setup

Orientation

Printing the body tilted with the nose upward provides the best balance of:

• Surface quality
• Print time
• Support usage

Several angles were tested. The best overall result was achieved around 65° of tilt, minimizing supports while maintaining consistent surface quality.

Plate & Filament Strategy (Strongly Recommended)

The entire model can be printed on a single plate, but for best results:

• Plate 1: Main body
  • 3 colors
  • + dedicated support interface
  • total of 4 filaments (Body paint, silver for metal, black for trim, support material)
• Plate 2: Boosters, taillights, wheels, and small detail parts
  • includes any part with the 4th color, which is red
  • total of 3 filaments (silver for metal, black for trim, red for tail lights, support material)

Using Support for PLA/PETG as a support interface allows the support interface Z-distance to be set to 0, which provides:

• Cleaner supported surfaces
• Easier support removal
• Better finish on complex geometry

With a single AMS (4 filaments), splitting the model across two plates allows the use of five total materials, including red for detail parts.

🔩 Assembly

Assembly is simple and beginner-friendly:

• Most parts require a single small drop of super glue
• Hold parts in place for ~30 seconds
• All parts are clearly labeled in Bambu Studio’s Object List
• Reference the included photos if placement is unclear

✅ Tips for Best Print Results

While this is a long print, it is not a difficult one when the following tips are followed:

• Ensure all filaments are completely dry
• Strongly recommend using Support for PLA/PETG
  • Significantly better supported surface quality
  • Much easier support removal
• Calibrate flow dynamics for each filament
  • Bambu auto-calibration works for all filaments except Support for PLA/PETG
  • Perform Manual Calibration for the support material
    • My final K-factor was 0.09, which differs notably from the default

🏁 Final Notes

This Dominus is designed as a display model, with an emphasis on clean surfaces and strong visual impact in multi-color prints.

If you’ve printed the Octane or Fennec versions, this one will feel familiar — just tuned for the Dominus’ longer, flatter body.

Enjoy the build, and happy printing.
