Resin printers have become increasingly affordable and popular, but creating time-lapse videos of prints on these machines can be more challenging compared to filament-based printers. However, Fraens devised a clever way to make time-lapse videos on any resin printer. The process involves using a smartphone, preferably one you no longer use regularly. The standard camera app on the phone is replaced with Open Camera to prevent it from closing during long idle intervals. A Bluetooth dongle is employed to trigger the camera, connected via a simple transistor circuit to an Arduino output. The Arduino, in turn, utilizes a light-dependent resistor (LDR) placed inside the resin printer’s bed to capture the right moments. The Arduino code initiates the Bluetooth dongle, capturing a series of still images later combined using DaVinci Resolve.
This DIY approach enables users to create captivating time-lapse videos of their resin 3D prints without the need for specialized equipment. It’s a testament to ingenuity in the 3D printing community, providing a workaround for a common challenge faced by resin printer enthusiasts.
