FLEXI-SAUR

FLEXI-SAUR

This project highlights an important capability of 3D printing, called “print-in-place”. The ability to construct a fully assembled item from scratch, complete with working hinges and articulation, is currently unique to 3D printing. Across 2 x 90-minute lessons, students will create a model of their chosen dinosaur type. Then they will split the model into sections and add print-in-place hinges. Lastly, they will 3D print their very own “Flexi-Saur”.
