Abstract
The disclosure provides a process for manufacturing a tread molding element configured to mold at least a portion of a tire tread, the process comprising the steps of modeling a three-dimensional shape of a tread molding element through a modeling program that can be recognized by a 3D printer; providing one or more plastic compositions comprising one or more thermoplastic polymers having a melting point of at least 180° C.; forming a tread molding element by 3D printing from the one or more plastic compositions; and optionally annealing the tread molding element.
