From SVG to Real LED Sign Fabrication Files (STL + DXF)

If you’ve ever built LED channel letters, you know how repetitive the setup can be.

Every new logo means:

  • rebuilding the structure
  • adjusting tolerances
  • preparing files for different machines

So I built a tool to automate that process.

🧠 The Problem

Working with SVG files for real-world fabrication isn’t as straightforward as it looks.

You usually need to:

  • recreate geometry in CAD
  • prepare separate files for 3D printing and laser cutting
  • manually adjust clearances and fit

And you repeat this… for every job.


🔧 The Approach

The idea was simple:

Take an SVG and turn it into fabrication-ready parts, not just a visual 3D model.

The tool generates:

  • STL files for base and top (structure)
  • DXF / STL for acrylic cutting
  • Consistent geometry ready for assembly

You can also preview the sign with lighting before exporting.


⚙️ Example Workflow

  1. Import SVG
  2. Generate structure
  3. Preview with lighting
  4. Export fabrication files

Instead of spending time rebuilding everything, you jump straight to production.


💡 Why This Matters

This isn’t about rendering.

It’s about reducing repetitive CAD work and making fabrication faster and more consistent.

If you work with:

  • CNC
  • laser cutting
  • 3D printing
  • signage production

you’ve probably dealt with this problem.


🧪 What I'm Still Improving

There are still open challenges, especially around:

  • tolerances depending on material
  • fit between printed parts and acrylic
  • edge cases in complex SVGs

💬 Feedback Welcome

I’m actively improving this based on real-world workflows.

If you’ve worked on similar fabrication setups, I’d love to hear how you handle it.
