A first experiment with an AI model: instead of using existing car images, I started by feeding the AI drawing tool descriptive prompts to generate a white-base 3D model that captures the exact exterior design I had in mind, free from the influence of any graffiti on the vehicle’s surface, thereby enabling MakerAI to construct a 3D model that stays true to my vision.
I provided a white-base rendering of the car’s front end, which reveals the interior seating layout and ultimately results in a model that only showcases the windshield—but the overall exterior appearance is already very close to the original concept I submitted.
The car generated by MakerAI based on my white-base prompt is nearly perfect; the main issue is that the wheels and certain details are fused together and cannot be separated. Given that my goal is to produce a highly detailed, small-scale 1:64 painted die-cast-style model, and considering ease of printing for others, I decided not to split the wheels since this minor limitation wouldn’t significantly affect the final print. I only imported the model into ZBrush for fine detailing and did not use Blender to separate components such as the tires and doors.
I’m extremely satisfied with the final result after adjustments. I also experimented with several different print orientations and bed settings to minimize layer lines and enhance the overall aesthetic appeal of the vehicle. I tested both PLA and PETG filaments, and both produced flawless prints.
For the final print, I positioned the model with the front facing upward at an angle of about 50 degrees, using tree-like supports to prop up the chassis, rear wing, wheels, and rearview mirrors, while strategically placing the support structures in inconspicuous areas at the bottom where they’re less likely to be visible.
The body was printed in silver filament and then painted with black glass for the windows, white flashing lights, red taillights, and black tires, achieving the look of a premium, high-end car. I’ve also shared images of the finished white-base model (scaled up to 300%, corresponding to a 1:64 scale) for your reference. You can scale the model up or down according to your needs; when scaling up, be sure to adjust the layer resolution to ensure a smooth surface finish.
The final finished model looks every bit as impressive as my collection of 1:64 alloy die-cast cars.
