MDF Board 3mm (1/8") Laser Box & Kerf Generator
Pre-loads 3mm material thickness and laser kerf offset to generate a ready-to-cut 6-panel finger-jointed box with instant .SVG download.
For MDF Board 3mm (1/8") (3mm thickness), an average 20W diode laser burns away 0.13mm of kerf. Our SVG generator expands all finger tabs outward by +0.065mm (0.13/2) to deliver a tight, glue-free press fit.
Box Geometry & Laser Kerf Settings
Measure with digital calipers; standard 3mm ply often measures 3.15mm.
Beam width compensation
Height: 54mm
Compatible directly with LightBurn, xTool Creative Space, Glowforge, and Inkscape. Red stroke (#ff0000) is pre-configured for Vector Cutting.
Laser Honeycomb Bed & Air Assist Pump
High-flow 30 PSI air assist pump and steel honeycomb plate to eliminate laser charring and back-flash scorch marks.

Mathematical Kerf Compensation for MDF Board 3mm (1/8")
How beam offset shifts vector coordinates to achieve a tight press-fit finger joint.
The focal spot of a laser vaporizes a thin channel of material along the vector path.
Shifting the cutting path outwards by half the beam width ensures the finished wooden tab matches the nominal joint slot.
Alternating male tabs and female slots around perimeter corners.
Engineering Specifications & Troubleshooting Guide: MDF Board 3mm (1/8")
Factory-tested parameters, common failure modes, and workbench best practices.
- Extremely consistent thickness across the entire sheet.
- Produces dark charred edges that should be sealed before painting.
Measuring material thickness with a tape measure; sheet goods like Baltic birch have manufacturing variances of ±0.25mm. Always measure with a digital caliper.
