ColorStack

SVG to STL

Vector SVG files are ideal for logos and signs. Rasterize or export PNG from your editor, then use FlatStack for flat multicolor plates or ColorStack mode for layered optical prints.

Best for clean logo edges on flat multicolor prints.

Open FlatStack

Who it is for

  • Brand designers without CAD
  • Makers printing client logos
  • Badge and keychain sellers

What you can make

  • Flat logo plates
  • Multicolor signs
  • Layered brand marks (via ColorStack mode)

How it works

  1. 1

    Prepare SVG

    Flatten transparency and expand strokes in Illustrator, Inkscape, or Figma.

  2. 2

    Export PNG at print resolution

    Upload to FlatStack or ColorStack—browser processing uses raster input.

  3. 3

    Assign colors to layers

    Reduce similar colors for reliable filament changes.

  4. 4

    Export STL

    Scale in slicer if needed; verify wall thickness for small features.

Export formats

STL (flat multicolor plate) · 3MF (multicolor flat print on Pro)

Frequently asked questions

Can ColorStack import SVG directly?
Use a high-resolution PNG export for predictable results. Direct SVG ingestion may be added later.
Why FlatStack for logos?
Logos are usually front-viewed and flat—FlatStack avoids unnecessary height variation.

FlatStack flat multicolor prints

FlatStack is for flat color surfaces, not height-based lithophanes. Upload artwork and build a thin multicolor plate ready for STL or 3MF export.

Image to STL

Turn 2D images into 3D printable STL meshes. Pick ColorStack, LithoStack, or FlatStack depending on whether you need layers, backlit relief, or a flat plate.

How to create flat multicolor 3D prints

Flat multicolor prints are front-viewed plates with distinct color layers. FlatStack quantizes artwork into printable bands on a thin solid mesh.
