I 3D Printed Origami [video]

When I got my first 3D printer one of the first things I learned, in a surprising twist, was how great they are at printing flat things.

The mini linear motion volumetric display is pretty neat too. https://www.youtube.com/watch?v=KgT20tHpk1g

Reminds me of Henry Segerman's expanding racks. Geared crazyness! https://www.youtube.com/@henryseg/videos

I wonder how their slicer is handling the infill angles. I suspect the bridge detection is only kicking in on the top layer, which ensures the infill angle is perpendicular to the gap. The bottom layer is going to follow a global angle and eventually run parallel to a hinge as the design gets complex (hence a later design failing and requiring thick hinges).

Painting infill angles would be tedious. I bet with concentric infill and some clever zero width cuts you could make all of the hinges perfectly perpendicular.

Thanks for sharing! I absolutely adore the meshing of mechanical engineering and origami. I cannot believe I never considered it.

Really cool!
