Systems and methods for 3D printing with multiple exchangeable printheads

A system, comprising

• a printhead module;
• wherein the printhead module comprises first mechanical interfaces and first electrical interfaces for coupling with one or more printheads,
• wherein the one or more printheads are configured to be exchangeably installed in the printhead module through the first mechanical and electrical interfaces;
• a platform module, wherein the platform module is configured to support a workpiece;
• a motion module, wherein the motion module is configured to move the printhead module in three dimensional directions relative to the platform module;
• a controller module,
• wherein the controller module comprises a controlled area network bus (CAN bus),
• wherein the CAN bus is coupled to the first electrical interfaces;
• wherein the controller module is configured to automatically configured a printhead of the one or more printheads installed in the printhead module through the CAN bus.
