The Ultimate Guide to Vector Files: Why They're the Best for Laser Cutting

Choosing the right file format for laser cutting can be confusing, especially with so many options available. The wrong choice can lead to a lot of frustration. It's crucial to pick a format that ensures precision and efficiency. This is where vector files come in as the best file format for laser cutting. Unlike raster images that are limited by resolution and pixelation, vector files offer clean, scalable, and precise paths for the laser to follow. In this article, we'll explore why vector files are the optimal choice for laser cutting, ensuring your projects turn out perfectly every time.

What are Vector Files?

Vector files are digital graphic files that are based on mathematical formulas. These formulas represent lines, curves, and shapes, allowing the images to be scaled up or down without any loss of quality. Unlike raster files, which are made up of pixels, vector files are composed of paths. This quality makes them ideal for precision-based applications like laser cutting, where every millimeter counts.

Common Types of Vector Files

1. Scalable Vector Graphics (SVG): SVG files adapt well to different screens and resolutions. Their ability to render smoothly on high-resolution displays makes them perfect for web graphics. SVGs are versatile, supporting features like gradients and animations, and are ideal for interactive web design.
2. Encapsulated PostScript (EPS): EPS files, known for their precision, are great for printing high-resolution images like banners and business cards. They combine bitmap data with vector coding, allowing detailed adjustments of visual elements. EPS is a go-to for quality-focused designs.
3. CorelDRAW Files (CDR): Associated with CorelDRAW software, CDR files are used widely in the design industry. They offer compatibility with most design software, making them a versatile choice for vector-based designs.
4. Adobe Illustrator Files (AI): Created by Adobe Illustrator, AI files are popular in print and digital graphics. Known for scalability without quality loss, they are ideal for logos and complex designs. However, editing AI files usually requires Adobe Illustrator.
5. Portable Document Format (PDF): PDFs are versatile, suitable for text, forms, and graphics. While they support both vector and raster graphics, they're often used for finalized designs due to their compatibility and wide acceptance.
6. Drawing Exchange File (DXF): Widely used in engineering and architecture, DXF files facilitate the sharing of 2D and 3D drawings across various CAD applications. Being open-source, they offer flexibility in viewing, modifying, and converting, without being tied to specific software.

Vector Files v.s. Raster Files

We can clearly see the differences between them after we zoom in these two pictures of different format, (The left is a vector file, and the right is a raster file.)

Raster files are images made of a grid of pixels. Each pixel is a small square of a specific color. When many pixels come together, they form an image. When you take a photo with a digital camera, it creates a raster file.

On the other hand, vector files are collections of points and lines controlled by math formulas. These files store information about where lines start and stop, their shapes, whether they curve and how much, and even details like line weight, color, and if they form a closed shape with a fill color.

So, after comparing these two kinds of files, we find that vector files are more suitable for laser projects for the following reasons:

First, vector files are made of lines and curves, making it easy for the laser to follow a path. In raster images, lines are actually stepped pixel representations of straight lines.

Second, vector images are resolution-independent, meaning they can be scaled infinitely. Whether you enlarge your design 100 times or reduce it, the quality stays the same. This is not the case with raster images. Raster images have a fixed number of pixels, so their image quality is limited.

Way to Convert Your File to Vector

When doing laser cutting, we need to use vector files. First, import your picture file into LightBurn. To convert other formats into vector files, we can use the "Trace Image" tool in LightBurn. Here's how:

Step1: Go to the top menu, select "Tools," then "Trace Image." Alternatively, use the shortcut Alt + T.
Step2: Right-click on the image and choose "Trace Image" from the pop-up menu.

Through these steps, LightBurn will convert your raster image into a vector graphic.
