Free Laser Cut Gear Generator | Closed-Loop DXF & SVG for Laser Cutters

GearDXF generates clean, continuous closed-loop vector geometries designed specifically for laser cutting. Export DXF and SVG files that import smoothly into LightBurn, LaserCAD, and RDWorks without open loops or double lines. Apply backlash compensation to account for laser beam kerf width.

Key Features

• Clean closed-polyline DXF (AutoCAD R12 format) and SVG exports
• Zero overlapping segments or micro-arcs that cause laser stuttering
• Backlash control to offset laser beam kerf width (0.1mm - 0.3mm)
• Spoke cutouts to minimize laser cutting time and material waste
• Supports wood, plywood, MDF, POM (Delrin), and acrylic fabrication
• 100% free with no watermark or file size restrictions

Frequently Asked Questions

How do I compensate for laser kerf when cutting gears?

Laser beams typically burn away 0.1mm to 0.25mm of material (kerf). In GearDXF, adjust the backlash parameter to account for this clearance so your cut teeth mesh at the exact pitch diameter.

Are exported DXF files compatible with LightBurn?

Yes! GearDXF exports continuous closed-path DXF polylines that LightBurn recognizes immediately as closed cut layers with zero open vertices.

Which plastics are best for laser cut gears?

Cast acrylic (PMMA) cuts with polished edges for light decorative models. For functional mechanical loads, laser cut Delrin (acetal/POM) provides superior wear resistance and low friction.
