Every week we receive files that need to be fixed before we can cut them — wrong format, wrong scale, rasterized instead of vector, or missing geometry. A few minutes of prep before you submit can save hours of back-and-forth.
Here’s exactly what you need to know about file formats for laser cutting acrylic parts.
The Short Answer
We accept DXF, SVG, vector PDF, AI (Adobe Illustrator), and EPS. DXF is the most reliable format for precision parts. Vector PDF is the most universally accessible. SVG works well for simpler shapes.
Format-by-Format Breakdown
DXF (Drawing Exchange Format) — Preferred for Precision Parts
DXF is the industry standard for CNC and laser cutting. It’s a vector format that natively supports the types of geometry used in precision fabrication: lines, arcs, circles, splines, and polylines. Most CAD and design software (AutoCAD, SolidWorks, Fusion 360, Rhino, Illustrator) can export DXF.
Tips for DXF files: Use DXF 2000 or 2004 format for maximum compatibility. Make sure all geometry is on a single layer or clearly labeled layers. Use closed polylines for shapes you want fully cut out. Delete all text, dimensions, and construction geometry before exporting.
Vector PDF — Most Accessible Option
A vector PDF exported directly from Illustrator, Inkscape, or a CAD package works well. The key word is “vector” — a PDF that’s a scanned image or screenshot cannot be used.
How to tell if your PDF is vector: Open it and try to zoom in to 400%. If lines remain sharp and crisp, it’s vector. If they get pixelated and blurry, it’s rasterized and we can’t use it as-is.
Tips for PDF files: Export at 1:1 scale with units clearly specified. Make sure outlines (strokes) represent cut lines, not filled areas. Don’t include crop marks or bleed areas in the cut layer.
SVG (Scalable Vector Graphics)
SVG is a web-friendly vector format that works well for laser cutting. It’s common output from Inkscape, Illustrator, and newer CAD tools. SVG handles curves and complex shapes well.
Watch out for: SVG files sometimes embed rasterized images within a vector container. Check that your cut paths are actual vector paths, not images placed inside an SVG wrapper. Also be careful with unit settings — SVG dimensions can default to pixels, which may not reflect your intended physical dimensions accurately.
AI (Adobe Illustrator)
Native AI files work fine if you’re using a recent version of Illustrator. Make sure cut paths are on their own layer, clearly labeled, and that any stroke widths are set to hairline (0.001pt or similar) to indicate cut lines vs. decorative elements.
EPS
EPS is an older vector format that still works. It’s less common today but fully supported. Same rules apply: clean geometry, 1:1 scale, no rasterized content.
Universal Rules for Any Format
- 1:1 scale. Your file should represent the finished part at actual size.
- State the units. Include a note specifying inches or millimeters.
- One part per file (or clearly labeled if multiple parts).
- Cut lines only. Remove all annotation, dimensions, title blocks, and non-cut geometry.
- Closed paths. Make sure shapes that should be cut out are fully closed loops — no gaps in the outline.
- No kerf compensation needed. We handle that on our end.
What If I Only Have a Sketch or Image?
Not a problem. Send us your sketch, photo, or PDF drawing and we can create a cut file from it and send it to you for approval before any cutting happens. There’s a charge for file preparation depending on complexity, but for most simple parts it’s minimal.
