A maker's file formats: SVG, DXF, STL, 3MF, LBRN, G-code
By the PandaFile team · · 7 min read
Between vectors, 3D, CAD, and machine files, a digital fabrication workshop handles a dozen formats with very distinct roles. Mixing them up wastes time — or material. This overview is part of the guide on organizing your design and fabrication files. For the exact list supported by the software, see also the formats guide.
Vector formats (2D)
These are the line-art files, used mainly for cutting and engraving:
- SVG: the standard vector format of the web and illustration (Inkscape, Illustrator).
- DXF: technical standard (CAD, CNC), precise on dimensions and units.
- EPS / AI: Adobe vectors, common in design work.
To prepare them without surprises, see preparing an SVG or DXF file for laser cutting and preparing a DXF drawing for CNC machining.
3D formats
Used in 3D printing and modeling:
- STL: the raw geometry of a model, the most widespread exchange format.
- 3MF: a richer project (multiple objects, colors, supports).
- OBJ / STEP: textured mesh or parametric CAD model.
To view them without a slicer, see previewing an STL file and managing versions in 3D printing.
Machine formats
Specific to a piece of equipment and a precise setup:
- LBRN / LBRN2: LightBurn projects for laser cutting.
- G-code (.gcode, .nc): sliced machine instructions, for CNC and 3D printing.
- XCS and others: projects proprietary to certain brands (xTool and the like).
To dig deeper: opening a LightBurn file (.lbrn2) and understanding a G-code file.
Graphics and document formats
PSD (Photoshop source), PDF (exports and drawings), PNG/JPG/WebP (raster images). For source files, see previewing a PSD, AI, or EPS without Adobe.
The real problem: seeing them all in one place
Most of these formats have no preview in Windows Explorer. A visual library that generates thumbnails for all your formats — vectors, 3D, machine, graphics — solves the problem in one shot. That's exactly what PandaFile does, 100% local. You can try it for free.
Frequently asked questions
What's the difference between SVG, DXF, and STL?
SVG and DXF are 2D vector formats (line art): SVG comes from drawing and illustration, DXF from technical CAD. STL is a 3D format that describes the geometry of an object to print. They aren't interchangeable.
Can a G-code file be used on another machine?
No: G-code is sliced for a specific printer or CNC, with a given profile and tools. On a different setup, you have to start over from the source model or drawing.
How can I preview all these formats without installing every piece of software?
With a visual library that generates thumbnails for all the formats (vectors, 3D, machine, graphics) in one place, without opening each file's original software.
