3D printing with resin has become almost as popular among Makers as 3D printing with filament systems. However, it is not quite easy to record appealing time-lapse videos of the printing process as known from filament-based 3D printers. Maker Fraens has now introduced a hack to record time-lapse videos for resin printers using a smartphone.
The trick: A Bluetooth remote control for the smartphone camera is controlled via transistor and Arduino. A light-sensitive resistor in the print area of the resin printer registers when the UV light of the device is active. The Arduino then sends signals to the Bluetooth remote control at the right time to trigger photos with the smartphone camera.
In a short video, Fraens demonstrates the method on an Anycubic Photon 3D printer. Using additional software, the many individual images can then be stitched together to create a fluid time-lapse video. The advantage of the approach is its ease of implementation with readily available components. He published details of his work in a detailed blog post.
