Abstract

A modular 3D printer system can include a base subsystem and multiple exchangeable components. The base subsystem can have a 3D motion module, a printhead module and a platform module. The multiple exchangeable components can include printheads having different configurations and functionalities, which can be exchangeably installed in the printhead module. The multiple exchangeable components can include platform supports having different configurations and functionalities, which can be exchangeably installed in the platform module.
