## What it is
Lumina Studio is a Python/Gradio application that converts images into slicer-ready multi-material 3D models for full-color FDM printing. It uses photographed calibration of filament light transmission to mix colors, supporting 2-8 color systems with 3MF export for BambuStudio and OrcaSlicer.

## Use cases
- convert an image into a full-color 3D print
- calibrate filament colors for multi-material printing
- export 3MF files for BambuStudio or OrcaSlicer
- print illustrations and photos in color on an FDM printer
- build a lookup table for filament color mixing
- set up a 2-8 color AMS print from a picture

## When to choose
- you want image-to-color-FDM printing with calibrated color accuracy
- you use Bambu Lab or OrcaSlicer multi-material systems
- you need reproducible color mixing via measured filament transmission

## When to avoid
- you need resin or SLA color printing
- you want automatic color without doing a calibration workflow
- you use slicers without multi-material 3MF support

## Facets
- artifact type: application
- maturity: active
- function: image-processing, data-visualization, developer-tools
- domain: graphics, hardware
- platform: python, cross-platform
- tags: 3d-printing, fdm, multi-material, color-mixing, 3mf, bambulab, orcaslicer, calibration, lut, gradio, automation, web-server
