Format Guide

We accept GLB, PLY, and ZIP or RAR OBJ bundles. Below you'll find export instructions for common 3D tools and tips for getting the best results.

GLB

Single-file binary glTF. Embeds geometry, materials, and textures in one file. Best compatibility across tools — recommended for most users.

Export from Blender

  1. Open your model in Blender
  2. File → Export → glTF 2.0 (.glb/.gltf)
  3. Set format to "GLB" (binary)
  4. Under Geometry, enable "Apply Modifiers"
  5. Under Data, ensure "Vertex Colors" or "Materials" is checked
  6. Click Export

Export from Meshy

  1. Open your model in Meshy
  2. Click "Export" or "Download"
  3. Select GLB format — this is the default
  4. Download the file and upload directly

Export from Hyper3D (Rodin)

  1. Generate or open your model
  2. Click "Export"
  3. Choose GLB format
  4. Download and upload to FullColor3DPrint

PLY

Polygon file format with vertex color data. Commonly used for 3D scans, point clouds, and photogrammetry output. There is no texture support — all color must be baked into vertex data.

Export from Blender

  1. Ensure your model has vertex colors (check Data Properties → Color Attributes)
  2. If color is in textures, bake to vertex colors first: select mesh → Vertex Paint mode → use a bake plugin or manually paint
  3. File → Export → Stanford (.ply)
  4. Enable "Vertex Colors" in export options
  5. Use Binary format for smaller file size

Export from MeshLab

  1. Open your mesh
  2. If needed, transfer texture to vertex colors: Filters → Texture → Transfer Texture to Vertex Color
  3. File → Export Mesh As → PLY
  4. Enable "Vert: Color" in the export dialog

OBJ (ZIP or RAR)

Wavefront OBJ with a separate MTL file for materials and external image files for textures. Bundle all files into a single ZIP or RAR archive for upload. All files must be in the root of the archive — no nested folders.

Export from Blender

  1. File → Export → Wavefront (.obj)
  2. Enable "Write Materials" and "Write Normals"
  3. Under Path Mode, choose "Copy" and click the folder icon to embed textures
  4. This creates .obj, .mtl, and texture files in the same folder
  5. Select all exported files, then create a ZIP or RAR archive
  6. Upload the archive

Export from Autodesk Fusion™

  1. File → Export
  2. Change the file type to OBJ
  3. Click Export — Fusion creates a folder with .obj and .mtl files
  4. Open the folder, select all files, and create a ZIP or RAR archive (files must be at the root — not inside a subfolder)
  5. Upload the archive

General export (any tool)

  1. Export as OBJ with materials
  2. Ensure the .mtl file references texture filenames without path prefixes
  3. Collect the .obj, .mtl, and all texture images (PNG or JPG)
  4. Add all files to a ZIP or RAR archive — files must be at the root, not inside a subfolder
  5. Upload the archive

Troubleshooting

Model uploads but has no color

Your file may not include color data. For GLB, ensure materials and textures are applied. For PLY, confirm vertex colors are present. For OBJ, make sure the MTL and texture files are included in the archive.

Archive upload fails or model looks wrong

Check that all files are in the root of the ZIP or RAR archive — not inside a subfolder. Open the archive and verify you see .obj, .mtl, and texture files at the top level.

File is too large

The maximum upload size is 400 MB. Try reducing polygon count in your 3D tool (Decimate modifier in Blender), compressing textures to JPG, or lowering texture resolution.

Format not accepted

We currently support GLB, PLY, and ZIP or RAR archives (OBJ + MTL + textures). If your model is in another format (FBX, STL, STEP), convert it using Blender or an online converter — export as GLB for best results.
