ColorStack

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.

Ideal when your print is viewed from the front and should stay physically flat.

Who it is for

  • Badge and keychain makers
  • Shops printing logo signs and desk plates
  • Anyone making flat branded merch without CAD

What you can make

  • 3D printed signs and labels
  • Magnets, coasters, and badges
  • Logo plates and 3D printed business cards
  • Keychains with flat color faces

How it works

  1. 1

    Upload logo or artwork

    FlatStack quantizes colors into printable bands on a flat mesh.

  2. 2

    Set plate thickness

    Choose total thickness, base layer, and color layer height for your filament set.

  3. 3

    Optional border and back

    Add borders or a back image for two-sided flat prints when needed.

  4. 4

    Preview the flat face

    Confirm colors and edges before export—this is not a relief lithophane.

  5. 5

    Export STL or 3MF

    Download geometry sized to your bed and workflow.

Export formats

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

Frequently asked questions

Is FlatStack a lithophane tool?
No. Lithophanes vary height for backlit images. FlatStack builds a mostly flat multicolor surface for front viewing.
Can I print a business card?
Yes. Set card dimensions and keep color layers thin for crisp text.
SVG support?
Export SVG to PNG if needed, or use our SVG-oriented landing page for workflow tips, then upload to FlatStack.

Flat multicolor 3D print generator

Generate flat multicolor plates from images—perfect for signage, merch, and branded parts where a lithophane or painted relief is not the goal.

Logo to STL

Turn brand marks into physical prints—desk signs, badges, magnets, and giveaway items—without modeling in CAD.

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.

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.
