Laser cut files are vector files, which serve as the blueprint for a laser cutting machine. They contain geometric data represented as paths or strokes, rather than individual pixels. Each path consists of a series of points, and the space between those points is filled to create shapes, lines, and curves.
Laser cutting machine supports multiple vector formats, including AI, SVG, CDR, EPS, PDF, and DXF. Here’s a breakdown of those various formats:
AI (Adobe Illustrator): AI is a proprietary file format developed by Adobe for its Adobe Illustrator product. AI files are made up of paths connected by points, rather than bitmap image data. They are the most popular choice for design projects that require laser cutting.
SVG (Scalable Vector Graphics): It is an XML-based vector image format that supports animation. SVG files are widely used due to their versatility and compatibility with various software. They retain their quality when scaled, and are considered one of the best options for crafting laser cutting designs.
CDR (CorelDRAW): This is a file format for CorelDRAW, a vector graphics editor. It is a proprietary format, but it’s supported by several other software packages. CDR files contain elements such as lines, curves, shapes, and text, which make them suitable for a variety of laser cutting projects.
EPS (Encapsulated PostScript): EPS is a file format used to transfer PostScript artwork between applications. Typically used by graphic designers, EPS files can contain both bitmap and vector data and are often used when working with logos, illustrations, or types that require high resolution at any scale.
PDF (Portable Document Format): A universally accepted file format developed by Adobe, PDFs can contain a mix of text, images, and vector graphics. They retain the formatting of the original document and are widely used because of their broad compatibility. However, when they are to be used for laser cutting, they need to have vector graphics embedded in them.
DXF (Drawing Exchange Format): This is a file format for CAD data, designed to facilitate data exchange between AutoCAD and other software applications. DXF files can be more complex, containing additional information about the objects in the file, and are favored for more technical or mechanical designs.
