Vector / Laser Formats

Vector / laser formats are digital file formats used to define two-dimensional geometry for Laser Cutting, engraving, plotting, and vector-based manufacturing workflows. These formats store mathematical vector paths rather than pixel-based image data.

Vector geometry is widely used in digital fabrication because machines can follow geometric paths directly to generate motion and tool movement.

Common vector and laser formats include:

• SVG
• DXF
• AI
• EPS
• PDF

These formats are commonly used in fabrication workflows involving:

• laser cutters
• vinyl cutters
• CNC drag knives
• engraving systems
• plotting machines

What Are Vector Formats?

Vector formats represent geometry using mathematical paths instead of raster pixels.

Vector geometry commonly consists of:

• lines
• curves
• splines
• polygons
• text outlines
• bezier curves

Unlike raster graphics, vector geometry can be scaled without losing precision.

This makes vector formats especially suitable for fabrication systems that require accurate motion paths.

Vector Formats in Digital Fabrication

Vector-based workflows are common throughout digital fabrication.

Typical workflows include:

1. Creating geometry in CAD or vector design software
2. Exporting vector geometry
3. Importing the file into fabrication software
4. Assigning machine operations
5. Generating machine instructions
6. Manufacturing the part

Vector formats are essential in workflows involving contour-following machines.

Laser Cutting Workflows

Laser Cutting systems commonly rely on vector geometry for motion control.

Vector paths may define:

• through-cuts
• engraving areas
• scoring operations
• fold lines
• alignment marks

Different colors or layers are often used to assign different machine operations.

For example:

• red lines may indicate cutting
• blue lines may indicate engraving
• black shapes may represent raster engraving

SVG

SVG is a vector graphics format based on XML.

SVG is widely used in:

• laser cutting
• web graphics
• hobby fabrication
• browser-based design tools

SVG supports:

• vector paths
• bezier curves
• layers
• text
• scaling

Because SVG is lightweight and open, it is commonly used in maker-oriented fabrication workflows.

DXF

DXF is a CAD-oriented vector exchange format widely used in industrial fabrication.

DXF is common in:

• CNC Routing
• laser cutting
• plasma cutting
• engineering workflows

Compared to SVG, DXF generally provides stronger compatibility with CAD and CAM systems.

AI

AI is a proprietary vector graphics format associated with Adobe Illustrator.

AI files are commonly used in:

• graphic design
• packaging
• signage
• artistic fabrication
• laser engraving

Many fabrication systems can import AI geometry directly or through conversion workflows.

EPS

EPS is a PostScript-based vector graphics format commonly used in publishing and graphics workflows.

EPS supports:

• scalable vector geometry
• embedded graphics
• print-oriented workflows

EPS is frequently used for interoperability between vector illustration systems.

PDF

PDF can contain both vector and raster content.

In fabrication workflows, vector-based PDFs are commonly used for:

• laser cutting layouts
• fabrication drawings
• technical documentation
• printable templates

Many laser-cutting applications can directly import vector PDF geometry.

Vector Geometry Types

Vector fabrication formats commonly support:

These geometry types are converted into machine motion during fabrication.

Stroke and Fill Behavior

Laser and vector workflows often distinguish between:

• stroke geometry
• fill geometry

Typical behavior includes:

Different fabrication software may interpret stroke widths and fills differently.

Vector Precision and Scaling

Vector formats support mathematically precise scaling.

Advantages include:

• resolution-independent geometry
• clean machining paths
• accurate dimensional control
• efficient curve representation

Improper scaling settings may still introduce dimensional errors during fabrication.

Advantages of Vector Formats

Vector formats provide several important advantages.

• scalable geometry
• precise machine paths
• compact file sizes
• editable curves
• broad fabrication compatibility
• efficient contour representation

These characteristics make vector geometry central to many fabrication workflows.

Limitations of Vector Formats

Vector workflows also have limitations.

• limited representation of photographic detail
• software compatibility differences
• inconsistent layer handling
• possible curve conversion issues
• font compatibility problems

Complex fabrication workflows may require geometry cleanup before manufacturing.
