How to Make a Living Hinge Box with the Ray5 20W

How to Make a Living Hinge Box with the Ray5 20W A living hinge uses a pattern of cuts in a rigid material (wood or acrylic) to create a flexible hinge without separate hardware. Here's how to design and cut one. What Materials Work Thin wood or acrylic works best. MDF is not suitable. Living Hinge Patterns The cut pattern determines flexibility and strength. Common patterns: Classic parallel cuts: Alternating rows of cuts Simple, predictable flex Best for most box projects Herringbone pattern: Diagonal cuts in alternating directions More uniform flex across the hinge width Slightly more complex to design Honeycomb pattern: Maximum flexibility Good for large radius bends Designing in LightBurn or Inkscape 1. Determine hinge width (how wide the flexible zone is) 2. Create rows of cuts: length = hinge width - 5mm (leave solid edges) 3. Stagger rows by half the gap length 4. Row spacing: 1.5–2mm 5. Cut length: 80–85% of hinge width 6. Cut width: laser kerf (no design width needed — just a line) Settings for 3mm Birch Ply Living Hinge Speed: 400 mm/min, Power: 100%, 2 passes Or: 300 mm/min, 95%, 1 pass — test for clean cut Box Construction Living hinge boxes typically have: Top/bottom flat panels (no hinge cuts) Side panels with living hinge zones at fold positions Box joints or tabs at corners Soak the hinge area in water for 30 seconds before first bending — prevents cracking on tight radius bends.
