This device is specially designed for the Bambu Lab series 3D printers to enable time-lapse photography. It supports multiple shutter triggering methods, including Bluetooth shutter, wired shutter, and mechanical servo shutter, making it compatible with a wide range of external cameras. When the printer sends a shutter command, the device automatically triggers your camera to take photos, allowing you to easily capture every stage of the printing process. By combining these photos into a video, you can effortlessly create high-quality 3D printing time-lapse footage.
