FilaTint

FilaTint is multi-color painting for Bambu Studio 3MF projects, on iPhone and iPad. Open a project, brush filament colors onto any part with your finger or Apple Pencil, and export a 3MF that opens straight back in the slicer — every other byte untouched. OPEN ANY PROJECT Plates, objects and multi-part assemblies all load. Pick the exact part you want to paint from the object list. PAINT WITH REAL FILAMENTS Brush or Smart Fill using the filaments your project declares, with undo per stroke. Each part keeps its edits as you switch. Recolor a filament with a long-press, or add a new one based on an existing preset so it keeps the right material settings. PAINT FOLLOWS THE BRUSH, NOT THE MESH Triangles the brush only partly covers are split finely, so a small dab on a big flat face paints a clean disc. Fast strokes stay continuous. Smart Fill floods a whole face in one tap, and edge detection stops brush strokes and fills at sharp edges so paint doesn't bleed around corners. MADE FOR IPAD AND APPLE PENCIL Pressure changes brush size. Double-tap switches tools. Hover previews the brush or fill before you touch down, and your palm is ignored while drawing. Open several projects side by side in separate windows. YOUR FILE STAYS YOUR FILE FilaTint never rebuilds your project. It changes only the paint on triangles you repainted, and writes everything else back byte-for-byte. Paint done in Bambu Studio loads here as painted, and survives a round-trip. Added a filament? New color pairs get conservative purge values, so before a multi-color print, open the project in Bambu Studio and recalculate flushing volumes. PRIVATE BY DESIGN No account, no ads, no analytics, no tracking. Your 3MF files are imported, painted and exported entirely on your device. Bambu Studio is a trademark of its respective owner.
