Painter3D

Painter3D paints 3D models for multi-material printing, with Apple Pencil. Pick a filament, draw it onto the model, save — and PrusaSlicer opens the file with every colour on its tool, the printer chosen and the filaments loaded. It paints the way the slicer prints: a stroke splits the model's triangles as finely as it needs to, exactly as PrusaSlicer's own multi-material painting does, so what you see is what comes out of the nozzle. PAINTING • Apple Pencil pressure sets the brush size — press harder for a bigger brush • Brush, sphere or circle, with a size and a level of detail • Smart fill, bucket fill and single triangles for clean flat areas • Paint with a finger too, if you like • A clipping plane to reach inside a model and paint what hides there • Undo and redo for every stroke • Show the model's own triangles, or how fine the painting has got THE SLICER'S FILE, KEPT Open a 3MF from PrusaSlicer, paint, save — Painter3D edits the file it opened, so the placement on the bed, the filament presets and every setting survive the round trip. PRINTERS Prusa XL with five tools, MK4S and CORE One with MMU3, CORE One INDX with four or eight tools — or the printer a 3MF already names. Add or remove extruders and change their colours. OPEN ANYTHING 3MF, STL, STEP, OBJ, PLY, glTF and GLB, from Files. A coloured or textured model comes in already painted: its colours are matched to your filaments, down to parts of a face. PLACE IT Set the size in millimetres, fit it to the printer, rotate it by a step, mirror it, put it on a face or drop it on the bed. Check the model for holes and loose parts and repair it without losing the paint, or cut a part away. TO BLENDER AND BACK Export a welded GLB, with a material per filament or vertex colours, and bring it back painted. THE LOW POLY ZOO Six finished animals — panda, penguin, orca, zebra, giraffe and lion — painted and ready to print, plus an unpainted capybara to colour in yourself. BUILT FOR IPAD A native iPad app with Metal rendering, in nine languages. No account, no tracking, nothing leaves your iPad. ALSO ON THE MAC The same app on the Mac, with in-scene rotate and scale, versions of your files, and a notice whenever the slicer saves over the one you have open.
