**Creating Stunning 3D Printing Time-Lapses: A Step-by-Step Guide**
As a 3D printing enthusiast, I've always been fascinated by the idea of capturing my print jobs in a time-lapse video. However, with so many options and settings to consider, it can be overwhelming to know where to start. In this article, I'll share my experience with creating stunning 3D printing time-lapses using a Raspberry Pi power ditch, SCADA working webcam stream through the OctoPrint software, and a DSLR camera.
**The First Attempt: Using a Raspberry Pi Camera**
My first attempt at creating a time-lapse involved using a Raspberry Pi camera. I downloaded the camera stand designed by Ethel Berg from Feeny Whirs and 3D printed all three parts in under three hours. After assembling the stand with an M3 screw and nuts, I placed the camera inside its secured its lids with a little bit of scotch tape and finally hot glue dated to sturdier pedestal.
To get a decent-looking stream image, I started adjusting the OctoLab settings and eventually decided on these which eventually spat out decent-looking time-lapses. However, when uploading the g-code of my three by fitting locally to the OctoPrint software and hitting print, the 3D printer did its usual heating up and levelling procedure. As soon as the actual print started, I noticed that the OctoLab software was working properly since it was moving the head and pads to a fixed position after every printed layer.
**The First Print: A Slightly Longer Than Expected**
After waiting for around 2 hours and 45 minutes, which was only slightly longer than what the slicer software calculated, obviously due to the time necessary for the fixed time-lapse position, the print was finally complete. The OctoLab software sped out a finished video file that I could download. However, this time-lapse looked blurry and only featured a resolution of 640 by 480.
**The Reason: Forgotten Resolution Settings**
The reason for the poor quality was that I forgot to set the resolution of the Raspberry Pi camera to 1920x1080 pixel in the Octa-Pi dot txt file as well as adjusting the focus of the camera. With those fixes, the streamed image looked way better, and thus I didn't have a test round with the OctoLab software which ultimately created a time-lapse which was not half bad.
**The Second Attempt: Using a DSLR Camera**
However, I was still looking for better image quality, and thus turned to my old DSLR camera, the Canon EOS 700D. By utilizing a 2.5 millimeter audio jack cable connecting one side of it to the external trigger ports of the camera and shorting the other sides sleeve and tip contacts, the camera takes a picture if the manual focus is selected.
**An External Trigger: A Switch**
To solve this problem, I salvaged a small switch from a microwave, cut off the 2.5 millimeter puck so that the two required wireless direct to the anomaly open contacts of the switch, and thus got an external trigger for the camera. Luckily, my 3D printer had a screw on its right side close to the z-axis which I removed and replaced with a longer M3 screw to secure the switch to the printer.
**Adding Hot Glue: A Simple Solution**
However, in the fixed time-lapse position, the print head does not activate the switch. To solve this, we can simply add a bit of hot glue to the switch, and just like that, the head reaches our switch now without a problem.
**The Final Print: A Success**
As soon as I added a tripod to the camera, positioned it properly next to my 3D printer, connected the external trigger switch, and started the 3D print with OctaLab's activators, the camera did its job without a problem. As soon as the print was complete, I removed its SD cards and imported all of the pictures into Adobe Premiere Pro software which functions nicely when it comes to creating time-lapses.
**The Result: A Stunning Time-Lapse**
Due to the high resolution of the pictures, it is also easily possible to add some movements. As a comparison, here's the time-lapse from the Raspberry Pi camera and here's the DSLR camera time-lapse which in my opinion truly looks stunning.
**Conclusion**
In conclusion, creating stunning 3D printing time-lapses requires patience, experimentation, and attention to detail. By following these steps and using a DSLR camera, I was able to create a time-lapse that truly showcases the beauty of my print job. I hope this article has inspired you to try your hand at creating stunning 3D printing time-lapses.
