Abstract

The present work is related to the fabrication of a scaffold with a customized shape through a variant of an additive manufacturing process often called liquid frozen deposition manufacturing, which consists in depositing layer by layer a polymer solution in a low temperature platform or chamber with an x-y-z motion platform. In this specific application, the x-y stage is actuated by high precision linear motors, located into a thermal chamber and must work at the temperature of -15° C, facing control problems related to variations of the electromagnetic interactions. Hence a multi-physics simulation has been developed in Open Modelica environment to understand the motor behavior and to allow the development of an amended control system.
