Laser Cut Box & Kerf Offset Directory
Eliminate loose or sloppy finger joints. Compensate for optical laser beam width (kerf) across diode and CO2 lasers to produce tight press-fit enclosures with instant one-click downloadable vector cutting SVGs for LightBurn, xTool Creative Space, and Glowforge.
Laser Box Cut SVG Generators by Material
Choose your sheet material to load calibrated kerf offsets and export ready-to-cut SVGs:
Baltic Birch Plywood 3mm (1/8")
Use masking tape on top and bottom to eliminate smoke scorch marks.
Cast Acrylic Sheet 3mm (1/8")
Cast acrylic laser cuts with polished glass-clear flame edges.
MDF Board 3mm (1/8")
Extremely consistent thickness across the entire sheet.
Basswood Plywood 3mm
Cuts rapidly with minimal laser power and clean light honey edges.
Baltic Birch Plywood 6mm (1/4")
Requires high-pressure air assist (30+ PSI) to prevent edge burning on thicker cuts.
Laser Beam Kerf Offsets by Material & Laser Power
Kerf is the material thickness vaporized by the laser beam. Finger joint tabs are expanded outward by +Kerf / 2 to create an interference press-fit:
| Laser Material | Nominal Thickness | 10W Diode Kerf | 20W Diode Kerf | 40W CO2 Kerf | 80W CO2 Kerf | Direct Tool |
