What started as a personal project to learn the laser cutter at my local makerspace quickly turned into a small-scale production run. By combining GIS data, vector design, and batch manufacturing techniques, I built a multi-layered wooden topographical map of my neighborhood that eventually scaled into fulfilling 43 custom orders.

43 Units Orders Fulfilled
12h → 3h Build Time per Unit
>50% Laser Cycle Reduction

Lean DFM and Process Optimization

Scaling from a single prototype to a 43-unit run meant I had to completely rethink how these maps were made. The first version simply took too long to cut, wasted a lot of wood, and was incredibly tedious to assemble.

The Prototype
Initial Bottlenecks
  • Running separate cut files for every single physical layer
  • Stopping to manually recalibrate the laser focus between cuts
  • Poor part layout leading to wasted material and long laser travel times
  • ~12 hours of total end-to-end build time per map
The Production Run
Batch Manufacturing
  • Combined all layers and frame components into just two nested cut files
  • Tightly nested parts to maximize the wood sheet and reduce laser travel
  • Switched to batch processes for staining, clamping, and gluing
  • Cut laser time by over 50% and dropped total build time to ~3 hours

GIS Data & Vector Design

Turning raw geographic data into a clean, cuttable design required a structured vector workflow:

  • Data Extraction: I pulled the raw road networks and land boundaries using the Google Maps API and SnazzyMaps to isolate high-contrast vector lines.
  • Vector Optimization: Using Inkscape, I separated the map into three physical layers: the water basin, the base land terrain, and the top road grid. I cleaned up the vector nodes to remove stray paths, account for the laser kerf, and ensure the delicate road networks remained structurally intact.
  • Custom Coordinate Pin: To personalize each map, I added a custom marker pin placed at the client’s exact latitude and longitude.

Color Variants

To offer a few different styles without slowing down batch production, I offered three standard stain colors for the map’s background water layer.

Black Topographical map with black water background
Deep Blue Topographical map with deep blue water background
Light Blue Topographical map with light blue water background

Production Results

Over the course of a 8 months, I managed the entire process from buying the raw wood and running the laser cutter to final assembly and shipping.

Key takeaways from the production run include:

  • CNC Laser Operations: Dialed in the laser power, speed, frequency, and focal distance settings across various wood thicknesses to get perfectly clean, repeatable cuts.
  • Assembly Jigs: Built standard jigs for clamping, gluing, and finishing that cut the manual assembly time per unit by 75%.
  • Final Delivery: Manufactured and delivered 43 custom maps, successfully turning a hobbyist makerspace project into a reliable small-scale production run.
