活动铰链生成器

设计激光切割活动铰链(kerf 铰链),并将交错切缝图案导出为 DXF 或 SVG,让平整的胶合板或亚克力可以弯曲——全部在浏览器中完成。

板材沿列方向弯曲。更短的连接和更密的间距可获得更小的弯曲半径。

How it helps

Staggered straight-slit (kerf) pattern that lets flat wood or acrylic bend.
Set cut length, link width, column spacing, margin, and an optional panel border.
Bends across the columns — tighter spacing and shorter links give a smaller radius.

Best practices

  • - Cut a small test strip first — the right link width depends on your material and thickness.
  • - Thinner material and shorter links bend tighter without snapping.
  • - Keep a margin so the hinge has solid material to attach to on each side.
  • - Run the pattern perpendicular to the direction you want the sheet to curl.

Limitations

  • - It makes the classic straight-slit kerf hinge — no wavy or torsion-spring lattices yet.
  • - There is no automatic minimum-radius calculation; test your material to confirm the bend.
  • - Very thin links can be fragile; cut a sample before committing to a full panel.

FAQ

What is a living hinge?

A living hinge is a pattern of staggered slits cut into a flat sheet so it can bend along a line without a mechanical hinge. The thin bridges between slits flex like tiny springs.

Which way does it bend?

The sheet flexes across the columns of slits. Orient the pattern so the columns run along the line you want to fold.

What materials work?

Thin plywood and acrylic are the most common. Thinner stock and shorter links bend to a tighter radius before breaking.

How do I get a tighter bend?

Reduce the link width and column spacing, or use thinner material. Always cut a test strip first.
