Do things that don't scale.
— Paul Graham
A small desktop rotational casting machine built from Lego Technic components, designed to reproduce TomyTones 3D printed figures in resin using a rotocasting process.
Concept
Rotocasting distributes liquid resin evenly across the inside of a hollow mould by rotating it on two axes simultaneously. A Lego Technic drivetrain provides the bi-axial rotation. The TomyTones figure mould is mounted on the machine, allowing multiple cast copies to be produced from a single 3D printed master.
