Exploring Vector Design Tools: Inkscape vs LightBurn
In the world of design and digital fabrication, choosing the right tool can make the difference between a smooth workflow and one filled with complications. Today, I want to share my experience using two programs that, while different in focus, are essential in my daily work at the FabLab: Inkscape and LightBurn.
Inkscape: The Power of Vector Design
What is Inkscape?
Inkscape is an open-source, completely free vector graphic design software. It is designed to create and edit vector graphics in SVG format, making it a versatile tool for illustrations, logos, technical designs, and more.
What is it used for?
Inkscape is ideal for:
- Creating graphic designs from scratch.
- Editing and manipulating SVG files.
- Creating complex illustrations with advanced path and node editing tools.
- Preparing designs for printing, laser cutting, or CNC (though it requires additional steps).
My Experience with Inkscape
First Steps in the Inkscape Environment
When opening Inkscape, I was greeted with a clean but feature-packed interface. In the first image, I show the workspace, where we can see how to create a new file and get familiar with the basic tools. While it may seem overwhelming at first, it becomes more intuitive with practice.
Drawing a 3D Cube
In the second image, I used basic shape and line tools to draw a 3D cube. Inkscape makes it easy to create geometric shapes, but achieving professional results requires a good grasp of its editing tools.
Sketching a Personal Project
In the third image, I show a sketch of one of my projects. I used lines and colors to bring the design to life. While the result isn’t perfect, Inkscape allowed me to experiment with shapes and fills creatively.
A Not-So-Professional Design
In the fourth image, I share a more elaborate design visualization. Although I haven’t fully mastered the software, Inkscape has allowed me to explore my creativity and learn step by step.
LightBurn: The Specialized Tool for Digital Fabrication
LightBurn is a design and control software for laser cutters and CNC machines. While it’s not a full graphic editor like Inkscape, it is optimized for preparing vector files (SVG, DXF) and sending them directly to machines.
What is LightBurn?
LightBurn is a design and control software for laser cutters and CNC machines. While it’s not a full graphic editor like Inkscape, it is optimized for preparing vector files (SVG, DXF) and sending them directly to machines.
Why is it a Great Option?
LightBurn is perfect for:
- Creating and editing vectors quickly and easily.
- Preparing DXF and SVG files for laser cutting, CNC, or engraving.
- Controlling and configuring machines directly from the software.
- Optimizing workflows in a FabLab.
My Experience with LightBurn
The LightBurn Environment
In the fifth image, I show the LightBurn interface. Its layout is simpler and more focused on digital fabrication. From the start, I noticed it’s more agile and easier to use than Inkscape for my FabLab needs.
Creating Basic Shapes
In the sixth image, I used basic line and shape tools to create a simple design. LightBurn allows for intuitive vector drawing, making it easy to create designs ready for cutting.
Shapes and Defined Text
In the seventh image, I show how shapes and text can be combined to create more elaborate designs. LightBurn includes specific tools for adjusting cutting and engraving parameters, making it ideal for practical projects.
Vectorizing Images to Black and White
In the eighth and ninth images, I explore the ease of vectorizing black-and-white images. LightBurn has a built-in function to convert images into vectors, which is very useful for laser engraving or vinyl cutting.
A Complete Example: The MELI Mascot
In the tenth image, I show two versions of my university’s mascot, MELI. LightBurn allowed me to create a clean and precise vector design, ready to be used in different applications.
From 2D to 3D: Adding Volume to My Designs
In the eleventh image, I present three versions of the same design: in color, as vectors, as outlines, and a 3D-printed version. LightBurn has enabled me to create DXF files that I can then use in other tools to add volume to my designs and create physical objects.
Comparison Table: Inkscape vs LightBurn
| Feature | Inkscape | LightBurn | Conclusion (From My Perspective) |
|---|---|---|---|
| Primary Focus | Vector graphic design (creation and editing of SVG). | Control and design software for laser cutters and CNC machines. | LightBurn is more aligned with my needs in the FabLab, as it focuses on digital fabrication. |

| Workflow Efficiency | Slower for preparing files for cutting, as it is not specialized. | More agile and optimized for preparing and sending files to machines. | LightBurn is more efficient for my workflow in the FabLab. |
| Integration with Other Tools | Requires additional steps to convert SVG to DXF or prepare files for CNC, laser, or vinyl cutting. | Integrates seamlessly with machines and digital fabrication tools. | LightBurn simplifies my workflow by generating files ready for CNC, laser, and vinyl cutting. |
| Price | Free and open-source. | Paid (one-time license, affordable). | Although Inkscape is free, LightBurn offers added value that justifies its cost. |
Final Conclusion (From My Perspective)
Inkscape is ideal if I need to create complex graphic designs from scratch, but it is not optimized for digital fabrication.
LightBurn is more agile, user-friendly, and specifically designed for digital fabrication. It is perfect for preparing SVG or DXF files for CNC, laser engraving, vinyl cutting, and other tasks in the FabLab.
Decision: Since my primary focus is digital fabrication and not complex graphic design, LightBurn is the best option for me. Additionally, its ability to generate optimized DXF files allows me to easily integrate it with other tools for creating 3D objects, templates, and more.

Why I Chose SolidWorks
After testing and comparing these tools, I decided to stick with SolidWorks for several reasons:
- Software Mastery: I already have advanced experience and knowledge of SolidWorks, which allows me to work efficiently.
- Focus on Mechanical Design: SolidWorks is specialized in mechanical design, which is my primary area of work.
- Professional Tools: It offers advanced tools for parts, assemblies, and simulations, which are essential for my projects.
- Integrated Simulation: The ability to simulate stress, fluids, and mechanical motion directly in the software is invaluable for my work.
- Industry Compatibility: It supports widely used formats like STEP, IGES, and DWG, making collaboration with other professionals easier.
When to Use the Other Tools?
Blender: I occasionally use it for projects requiring organic modeling or advanced rendering, such as visual presentations.
Autodesk Inventor: It’s a good alternative to SolidWorks, but since I already master the latter, I don’t see the need to switch.
Tinkercad: I recommend it for beginners or quick, simple projects, but it’s not sufficient for my professional needs.
