Futuristic: SELFHEALING PIECES

We will have microscopic robots constantly repairing Lego pieces on a molecular level. These nanobots navigate around autonomously inside the material itself using their 3 anti-gravity pods and filling up micro cracks and scratches to prevent broken parts. It's equipped with an extruder fed by 3 tanks that hold all material components.

No more broken pieces, no more waste: Yay!
