That model you keep meaning to color?
The slicer is why it's still grey.
Your slicer makes you color one face at a time, so it sits in your downloads. Layerpaint fills a whole region in a click, then exports a Standard 3MF that prints exactly as you see it.

Drop in your model
Drag an STL, OBJ or 3MF onto the page. It loads right there in your browser, so the file never gets uploaded anywhere.
Paint by region
Layerpaint splits the model along its creases, so one click fills a whole panel. There's a brush and mirror painting for the fiddly bits.
Export a 3MF
One click saves a Standard 3MF. Open it in Bambu Studio, Orca or Prusa and your colors land on the right filament slots.
Click once. It floods to the edges.
Most painters make you color one triangle at a time. Magic floods out from a single click and stops by itself at the model's natural creases, so a whole panel, horn or plate fills in one move.
- ✓ Click a surface — it fills up to the creases
- ✓ Scroll to size it, one degree at a time
- ✓ Click again to drop your color
Paint a whole panel in one click.
In most tools you color one tiny face at a time. Layerpaint reads the model's hard edges and turns each surface into a region, so filling a dragon's wing is one click instead of an afternoon of them.
- ✓ Auto-partition by crease angle
- ✓ Magic Fill, brush, mirror & detail tools
- ✓ Snap-to-crease for clean, exact seams
Design in the filaments you actually own.
The color picker is stocked with real spools (Bambu, Polymaker, Prusament, Overture), so what's on screen is what comes off the printer. It also tallies the filament swaps on each layer, so a print that's going to crawl is obvious before you slice it.
- ✓ 600+ real filament colors, by brand
- ✓ Live per-layer filament-swap counter
- ✓ See a color's print cost before you commit
Export once. It opens already colored.
Layerpaint saves a Standard 3MF using the official Materials Extension, so Bambu Studio, OrcaSlicer and PrusaSlicer pick up your colors on their own. You won't be redoing the paint job in the slicer or wrestling with a broken import.
- ✓ Standard 3MF · official Materials Extension
- ✓ Colors map straight to filament slots
- ✓ No re-painting, plugins or uploads
Magic Fill
Tap a part — it floods to the natural seams. Scroll to size it, catch soft edges, close gaps.
Brush & Fine detail
Paint by hand; fine mode follows the plane you click. Respects the borders you've drawn.
Isolate & Cut
Slice the model with a dragged line and hide the side that's in your way, or drop a guard sheet that paint tools stop at.
Borders
Draw where colors should split. Encircling strokes auto-close their gaps; a broad eraser clears them.
Grow & clean-up
Spread a color, fill bare gaps, clean stray specks, and flag patches too thin to print.
Theme palettes
Warhammer, superheroes, fantasy, sci-fi — plus 600+ real filament colors and skin tones.
Color swap
Change one color to another across the whole model in a single click.
Symmetry
Mirror every stroke across an axis — perfect for figures and armour.
Print check
Scrub the print layer by layer, with a per-layer filament-swap counter.
One clean export
A Standard 3MF that opens already-colored in Bambu Studio, OrcaSlicer & PrusaSlicer.
