In this research, we develop a current, power, energy, and voltage monitoring system which is implemented on a 3D printer. The printer used is a 3D DLP (Digital Light Processing) printer, where this printer uses a 3D photopolymer resin that can solidify under a light source. We added IoT (Internet of Things) technology to make it easier for users to monitor 3D printer usage. One of the additional components used is the ESP 32, which functions as the main processor for processing and sending data. The system is equipped with a PZEM-004T sensor to transmit current, power, energy, and voltage readings. System testing is done by printing objects in three-dimensional form, including factory shapes, circles, pluses, triangles, and squares. Based on the test results, it is found that the longest response time is when the system prints a box object, which is 110 minutes, while the fastest response time on the plus object is 24 minutes. This proves that sending data using ESP32 can be used to implement IoT technology.
