AMS Splitter

AMS Splitter — Turn Textured & AI Meshes into Printable Multicolor Solids

Tagline / Short Description (one-liner)

One click turns any textured or AI-generated model into a single watertight,

multi-material solid — ready for Bambu Lab AMS multicolor 3D printing.

Full Description

The problem

AI model generators (Meshy, Rodin, Luma, Tripo…) and downloaded PBR assets look

great on screen but are a nightmare to print in color. The color lives in a texture,

not in the geometry — so your slicer sees one gray blob. Worse, AI meshes arrive as

a "patchwork" of hundreds or thousands of open, disconnected shells: not watertight,

impossible to slice cleanly, and impossible to assign filaments to.

The solution

AMS Splitter bakes the texture's real colors *into the geometry as separate

materials*, and rebuilds the model into one clean, watertight solid. The result is a

single object with N materials — one per color — which is exactly what Bambu

Studio (and other AMS/multi-material slicers) expect: one filament per material.

Load a model, press MAKE PRINTABLE (AMS), send to your slicer. That's it.

Key Features

🖨️ One-click Printable (AMS) — analyze colors, voxel-remesh into a single

watertight solid, and transfer the texture colors onto it via surface search (BVH).

🧩 Fixes broken AI meshes — turns thousands of open shells into one closed,manifold solid that slices without errors.

🎨 Faithful, saturation-preserving colors — each material keeps its true color

(vibrant greens, genuinely dark hair) instead of a washed-out average.

🧠 Smart color clustering (LAB + Cluster Headroom) — detects the dominant

colors and prevents large gradients (a dress) from swallowing small regions (hair).

☀️ PBR Shadow Reduction — ignores baked lighting/shadows so they aren't

mistaken for separate filament colors.

⚡ Fast numpy core (~20× faster) — a 1.5M-face mesh analyzes in ~5s instead of

~100s.

🧵 Bambu AMS ready — keep one multi-material object (recommended) or split into

separate physical parts.

🛠️ Built-in print prep — recalculate normals, remove doubles, make manifold,

add a gap between colors for multi-material fit, and merge-by-distance.

📦 Export GLB and material cleanup tools included.

How it works (3 steps)

1. Select a mesh with a Base Color texture and a UV map.

2. Set the number of colors (e.g. 4 for a 4-filament AMS) and press

MAKE PRINTABLE (AMS).

3. Export or send to your slicer — one object, one filament per material.

Perfect for

Multicolor 3D printing on Bambu Lab AMS, Prusa MMU, and other multi-material

systems.

AI-generated models from Meshy, Rodin, Luma, Tripo, and similar tools.

Turning downloaded PBR/GLB assets into printable colored objects.

Miniatures, figurines, busts, props, and display pieces.

Requirements

Blender 3.6 or newer.

A mesh with a UV map and a Base Color texture (or solid material colors).
