Layer Arta Toybox tool

A picture becomes
printable color.

Drop in a picture. It comes back as a stack of flat plates — each one printed in a single filament, stacked so the picture appears in real color and real depth. No multi‑material printer, no supports, nothing loose.

Works straight away in the tab — your pictures never leave your machine.

Seven colors in, seven flat plates out — stacked, this is what you get.

How it works

You do not print color. You print holes. The bottom plate is solid; every plate above it is solid except where a color below needs to show through. The top plate is just the linework. Every plate is the same sheet with a solid border, so you line the edges up and the art lines itself up.

Nothing is ever looseAnything that would float gets bridged with a thin tab automatically. If it somehow cannot be, the run fails loudly instead of quietly handing you a chip to glue.
No supports, everEvery plate is a flat shape pulled straight up. It cannot overhang. That is true by construction, not by luck.
Your actual filamentTell it which spools you own. Every color snaps to one of them, so what comes out is printable with what is on your shelf.
Checked before you sliceEvery file is verified watertight and single‑bodied. You get grams per plate measured from the real mesh.

Getting started

  1. Open it. The first load pulls down the graphics libraries once and caches them; after that it starts instantly, and it keeps working with no connection at all.
  2. Fill in your filament shelf first. Name and color for each spool you own. Everything after that is built only from those colors, so the result is printable with what you actually have.
  3. Drop a picture in. A verdict tells you how it will come out before anything runs.
  4. Print bottom to top, one filament per plate, then stack them with the edges flush.

What it can and cannot do

Best results: flat colors, bold shapes, hard edges, good contrast, and shapes that touch each other. Poster and sticker art is the sweet spot.

It cannot do: small text — anything under about 4 mm tall simply cannot exist at a 0.4 mm nozzle — smooth gradients, glows, reflections, or busy photographs. The app tells you which of these it has hit, and why, before you commit to a print.
