Polysynth’s eight-vat resin printer spins to switch materials

Polysynth reveals a multimaterial resin 3D printer with a carousel of up to eight small vats. The machine uses centrifugal spinning to fling uncured resin between dips, avoiding extra wash stages, and a precision servo locks the spinning portion to return the part to its original orientation within microns. It even showcases a resin capable of forming fully printed, multilayer PCBs and hints at dental applications. The system isn’t for sale yet and will require careful calibration and resin compatibility handling, but it could enable faster, more versatile home resin printing.
