Colorful 3MF / GLB Export

Download the complete model carrying the final color scheme as a 3MF or GLB file.

How to Generate a Multicolor 3D Print File

Four steps from textured model to a color-ready 3MF or GLB export.

1. Select a Textured 3D Model

Pick a textured 3D model from your Neural4D assets. The Multicolor tool works on models that carry PBR textures, so every color region is readable for the printing scheme.

2. AI Detects Color Regions

The AI analyzes the model surface and recognizes each colored region. It builds an initial color scheme sorted by the proportion of every region, so the print layout stays faithful to your design.

3. Fine-Tune Your Color Palette

Switch between Smart Color and My Colors, adjust the color count from 1 to 8, swap filament materials from the library, or type a custom 6-digit hex color. Every color is listed with the share of the region it covers.

4. Confirm and Export 3MF or GLB

Confirm and save your active scheme, then download the complete colored model. The default export is 3MF, and GLB is also available, so the model keeps its color scheme through the full printing pipeline.

Smart Color vs My Colors

Two ways to build the color scheme behind your multicolor 3D print file.

Compare	Smart Color	My Colors
How the scheme is created	AI detects color regions and returns a 4-color scheme by default	Applies your personal saved color scheme to the model
Palette size	Set by AI based on the detected regions	1-8 colors that you define
Reuse	A new scheme each time you generate	Saved once and reused across models and sessions
Best for	Quick multicolor preview	Consistent branding or personal style

Filament & Color Library

Match the color scheme to your printer setup with built-in filament materials or custom hex colors.

Option	Detail
PLA Basic	Standard PLA with a smooth matte finish, the most common choice for multicolor printing
PLA Matte	Low-gloss PLA that reduces layer-line visibility for uniform color surfaces
PETG	Durable and temperature-resistant, ideal for functional parts
ABS	Strong and heat-resistant, suited for engineering applications
TPU	Flexible and rubber-like, used for soft and grippy parts
Custom hex color	Any 6-digit hex code for exact brand or design colors

Frequently Asked Questions

What is a multicolor 3D print file generator?

A multicolor 3D print file generator turns a textured 3D model into a colored model ready for multicolor 3D printing. Neural4D's Multicolor tool detects color regions on the model, builds a color scheme, and exports the complete colored model as a 3MF or GLB file.

How does Neural4D create multicolor 3D print files?

The Multicolor tool analyzes the PBR textures of your Neural4D 3D model and recognizes the colored regions. It then generates a color scheme, sorts the colors by the proportion of each region, and applies the scheme to the model for a printable output.

Which 3D models can I color with the Multicolor tool?

You can color any textured 3D model in your Neural4D assets library. The tool reads the color regions from the model textures and converts them into a multicolor printing scheme, so the model should carry PBR textures before you start.

How many colors can I use?

The Multicolor tool supports color schemes from 1 to 8 colors. Smart Color automatically returns a 4-color scheme based on the detected regions, and you can fine-tune the count in the palette editor.

Which filament materials and colors can I apply?

The built-in filament library covers PLA Basic, PLA Matte, PETG, ABS, and TPU. You can also enter any custom 6-digit hex color code. Colors are listed by the proportion of the colored region they cover, with one decimal place.

What file formats can I download from the Multicolor tool?

You can download the complete colored model in 3MF format by default, or choose GLB. Both formats carry the final color scheme, so the model prints in color without extra configuration.
