Search any place or drop a GPX. Get a 3D terrain model, ready to print and display.

The map becomes a model.

1. Terrain

   Pick a place and its terrain lifts out as a smooth, solid model on a flat base, at real elevation. This one is Hong Kong Island, seen from the harbour.

2. Your route

   Your GPX becomes a raised ribbon that follows every switchback. This loop runs 7.9 km from Central up to the Peak and out along Lugard Road.

3. Water

   Victoria Harbour comes in as its own part, ready for blue filament.

4. Roads and buildings

   With City Mode, streets and buildings stand at real height, from open map data.

5. Real-world color

   Color from satellite imagery, reduced to a handful of filaments, so a multi-color printer paints the real landscape for you.

6. Then it prints

   Every feature, every layer. Your printer builds it up from the base, switching filament as each color appears.

Why it exists

We believe the places that matter to us should be more than memories on a screen. TrailMark3D makes the world tangible, turning meaningful places into physical objects you can create, hold, and keep.

Real terrain, your route, ready for your printer.

• Real elevation data

  Built from global elevation models, so every ridge and valley sits where it does on the ground.

• Your route on the land

  Drop the GPX from your watch or app and the trail runs across the model, raised or carved.

• Any place, no GPX needed

  Search a summit, a national park, a city or plain coordinates and build it straight away.

• Water and landcover

  Lakes, rivers, forest and rock as separate colors, ready for a multi-color printer.

• Jigsaw puzzle

  Split the model into interlocking pieces, up to 20×20, that slide together. Each piece is its own part in the 3MF.

• Cities in 3D (Pro)

  Buildings and streets rise out of the terrain, from Hong Kong's hills to San Francisco's grid.

• Multi-day trips (Pro)

  Up to 7 days as one tile per day, each at full print size, or the whole trip on one tile.

• Extension tiles (Pro)

  Need more ground? Add up to undefined matching tiles around a model. They print separately and line up edge to edge into one bigger map.

Three steps from a place to a print.

1. Pick a place or drop a GPX

   Search anywhere on Earth, or upload the track from your watch, Strava or Garmin.

2. Shape it

   Choose the size and shape, add water, landcover, contours or city blocks, and turn it around in 3D.

3. Download and print

   Get a print-ready STL or 3MF and slice it for your printer. Hang it, gift it, put it on the shelf.

Frame it to fit.

A square tile doesn't have to hang in a square. Drop your model into the frame builder and it sizes a frame around it. Pick the shape, set the border, add a name, then export and print it with the tile.

• Import your model and the frame sizes itself around it
• Circle, square, rectangle, hexagon or octagon, around any tile
• Raised text on the border, in its own colour with 3MF
• Connector keys to clip frames together, and screw holes to hang them

Print it as a puzzle.

Any model can come apart. Switch on the puzzle and the terrain is cut into interlocking pieces, peaks and valleys included. Choose how many, generate, and print a jigsaw of a place you know.

• The cut is drawn on the map as you set columns and rows
• A grid on square tiles, rings of cells on circles, hexagons and octagons
• Clearance tuned for FDM, so pieces slide together without fusing
• Every piece is its own object in the 3MF, spread out on the plate
