Laser Cut Topographic Map: Make Layered Topo Maps of Any Place

A laser-cut topographic map is one of the most satisfying maker projects there is: a real mountain, lake or coastline rebuilt as a stack of plywood, acrylic or cardboard layers, one sheet per elevation. The hard part was never the cutting — it’s getting a clean, correctly scaled contour file of the exact place you want. This guide covers the whole workflow, from picking the area to gluing the last layer.

What you need

• A vector contour file of your place — SVG for laser software (LightBurn, Glowforge, xTool Creative Space, Inkscape, Illustrator), or DXF if your machine runs from CAD.
• Sheet material of a known thickness: 3 mm plywood or MDF is the classic choice, acrylic for a glossy look, chipboard for prototypes.
• A laser cutter or CNC router with a bed big enough for your largest layer.

TopoLines draws the contour lines from real elevation data (a 30 m global terrain model, and 10 m or finer national data where it exists), so the shapes you cut are the actual terrain, not an approximation traced from a picture.

Step 1 — Pick the area and frame it for your bed

Draw the zone on the map. Two things matter more than for a poster:

• Aspect ratio. Frame the area to the shape of your final piece (and your bed), so you don’t crop terrain away later.
• Relief inside the frame. A layered map reads best when the area has a clear high point — a summit, a ridge, an island. Flat areas produce a few huge layers and nothing in between.

Mountains, volcanoes, islands, lake basins and fjords make the best cuts.

Step 2 — Choose the contour interval (it decides your layer count)

This is the single most important setting. Each contour level becomes one sheet, so:

number of layers ≈ (highest point − lowest point) ÷ interval

A summit rising 1,200 m above its valley with a 100 m interval gives about 12 layers — a comfortable build. The same terrain at 10 m gives 120 layers, which is weeks of cutting and a model taller than it is wide.

Rules of thumb:

Then check the stack height: layers × sheet thickness. Fifteen layers of 3 mm plywood is a 45 mm model — about right for an A4 piece.

Wider intervals also mean fewer thin slivers: tight intervals on steep slopes produce rings a fraction of a millimetre wide, which burn through or snap off.

Step 3 — Style the lines for a laser, not for a screen

Laser software reads paths, not looks. Before exporting:

• Turn off stroke tapering and gradient strokes. They’re great for prints, but a cut line should be a plain, uniform path.
• Turn off labels and annotations (contour labels, rivers, peaks) unless you want them engraved — in that case export them and assign them to an engrave layer in your laser software.
• Use a single thin stroke. Your laser software will treat every path as a cut line regardless of its width in the file.

Step 4 — Export SVG (or DXF) at the right scale

Export as SVG. The TopoLines SVG is grouped by elevation: every contour level sits in its own group, named after its height (contour-400m, contour-500m…). That’s exactly the structure a layered build needs — you open the file and each group is one sheet.

Import it into your laser software and scale it once, to the final width of your piece, keeping proportions locked. Every layer then shares the same scale and registers perfectly when stacked.

Prefer DXF if your machine runs from AutoCAD, Fusion or a CNC CAM tool: TopoLines exports the same contours as DXF too.

Step 5 — Split the layers and close the edge shapes

Here’s the step most tutorials skip. Contours that loop entirely inside your frame (a summit, a hill) are closed shapes and cut out cleanly. But contours that run off the edge of the frame are open lines — the terrain continues beyond your map.

To make each sheet a solid, cuttable piece:

1. Duplicate the frame rectangle onto every layer.
2. For each elevation group, close the open lines along the frame edge (in Illustrator or Inkscape: combine the lines with the rectangle and use shape builder / path → divide, keeping the area on the uphill side).
3. Put each sheet on its own layer or artboard, and add a small engraved number on each one (L01, L02…) so you assemble them in order.

A useful trick: on every sheet, also engrave the outline of the next layer up. It gives you a glue guide and makes alignment trivial.

Step 6 — Cut, stack and finish

• Test the power and speed on an offcut first; the right settings depend entirely on your material and machine.
• Cut from the bottom layer up, checking registration on the first two.
• Glue with a thin bead of wood glue (or acrylic cement for acrylic), aligning each sheet to the engraved guide below it.
• Optional finishes: stain alternating layers in two tones, paint water areas blue, or leave the burnt edges for contrast — they read beautifully as contour lines in their own right.

Common mistakes

• Interval too tight → too many layers, slivers that burn through.
• Rescaling layers individually → layers no longer line up. Scale the whole file once.
• Leaving tapered or gradient strokes on → odd results in laser software.
• Forgetting the material thickness → a model three times taller than planned.
• Picking a flat area → a few big plates and no sense of relief.

FAQ

What file format do I need for laser cutting a topographic map? SVG works with almost every laser package (LightBurn, Glowforge, xTool, Inkscape, Illustrator). DXF is the alternative for CAD-driven machines and CNC routers. TopoLines exports both.

How many layers should a laser-cut topographic map have? Usually 8 to 20. Divide the height difference in your area by the contour interval to get the layer count, and multiply by your sheet thickness to check the final height.

Can I make a laser-cut map of any place? Yes — TopoLines covers the whole world from real elevation data, with finer national data in many countries. Mountains, islands and lake basins give the most striking results.

Is the contour SVG free? Standard PNG exports are free. SVG and DXF exports use credits from a one-off pack (no subscription, credits never expire) — see pricing.

What’s the best material for a layered topo map? 3 mm plywood or MDF is the classic: cheap, easy to cut and glue. Acrylic gives a glossy, modern look; chipboard is ideal for a quick prototype.

Why are some contour lines open in my file? Lines that run off the edge of your map are open because the terrain continues beyond the frame. Close them along the frame edge to turn each layer into a solid cuttable shape (see step 5).
