Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but it can get tricky when you want to actively control the conditions inside the chamber. That’s where [Jayant Bhatia]’s Chamber Master project comes in.
This system is built around the ESP32 microcontroller, which provides control to various elements as well as hosts a web dashboard letting you monitor the chamber status remotely. The ESP32 is connected to an SSD1306 OLED display and a rotary encoder, allowing for navigating menus and functions right at the printer, letting you select filament type presets and set custom ones of your own. A DHT11 humidity sensor and a pair of DS18B20 temperature sensors are used to sense the chamber’s environment and intake temperatures.
One of the eye-catching features of the Chamber Master is the iris-controlled 120 mm fan mounted to the side of the chamber, allowing for an adjustable-size opening for air to flow. When paired with PWM fan control, the amount of airflow can be precisely controlled.
