This entry from Edis Alic's daily laser project series tackles one of the most visually impressive techniques in the laser cutting world: the living hinge. By cutting a precise pattern of thin, interleaved slits into a flat sheet of rigid 3mm MDF, the material becomes flexible enough to curve and wrap — transforming a stiff panel into a functional, foldable glasses case.

What makes living hinges worth understanding is that they exploit the geometry of cuts to change a material's mechanical behavior without changing the material itself. The spacing, length, and offset of each slit determines the bend radius and how much stress the wood can handle before snapping. Get the pattern wrong and it either won't flex or it'll fracture on the first bend. Get it right and you have a hinge with no moving parts, no fasteners, and no assembly.

The video is also a good look at product thinking for makers — Edis frames the project around something you could actually sell, which forces decisions about material cost, cut time (3mm MDF is fast and cheap), and finished appearance. That's a useful mindset shift from "cool thing I made" to "repeatable product," and it's the same design constraint that shapes real manufacturing.
