Design and printing techniques from the Alchemic Matter workshop: the joints, seals and tricks behind the projects, explained so you can use them in your own work.
FlexiSnap is a snap-fit seal for 3D-printed cases: a rhombus-shaped rib on a soft TPU cover squeezes through a narrow neck in a rigid PLA groove and locks behind it, closing the case against dust and splashes without gaskets or glue.
FlatHinge is a print-in-place hinge only 2 mm thick: two 0.8 mm leaves and a row of knuckles whose ends are interlocking 45° cones, printed flat with no supports and no pin.
How to decorate a cotton T-shirt with a 3D printer: print a flat graphic in soft TPU on baking paper, then fuse it into the fabric with a household iron. What matters, the steps and the common failures.
