Photogrammetry on a Pen Plotter

Originally I built a single head printer to draw vectors and while flat things are fun to draw, I decided to extract vectors from photogrammetry models and print them flat with a ballpoint pen. #

Eventually I didn’t feel I had enough control over the fidelity of the drawings. So I stripped all the electronics and rebuilt the plotter with an Arduino + gShield, a gentler printhead, and more power. #

My early scans were with a digital camera, which was great for large objects. Many forums later, I was able to build a rotating turntable and python server that ran on my phone to take photos and step to the next position, which allows for consistent detail on smaller objects. #
