The principle behind this scanner is the typical of a line scanner. A laser beam intercepts the object to be measured and a camera, positioned at a known angle and distance shoots a series of images. With some trigonometry considerations and optic laws it is relatively easy to reconstruct the Zeta dimension, the measurement of the distance between the object and the camera.
The Photon, an affordable 3D scanner, has already quadrupled its $80,000 Indiegogo goal, with still two weeks to go. Almost as gratifying: the Photon has generated a flurry of proposed uses for the device beyond the original “maker hobbyist” market they were targeting. The Photon is the first product from Toronto-based company Matterform, founded by friends and collaborators Adam Branejs and Drew Cox.
Last week I introduced slicing and CAD software, two key ingredients in a custom 3D Print. This week I’m going to cover the actual use of your machine, how to view and find 3D models, and venture into the still-budding world of DIY 3D scanning. Just like last time, all services listed are free (at least to a certain extent).
Toronto’s 3D-printed jewelry company Hot Pop Factory received a client request to come up with a fun 3D-printed holiday gift for each of their employees, and I think they knocked it out of the ballpark with what they came up with: 3D scanned and printed Pez dispenser head toppers!
Sebastian Korczak hacked together a 360° rotating 3D scanner using little more than a record turntable modified with Arduino, digital camera, and a laser pointer. Korczak’s laser was mated with a special lens to create a linear beam. The distortion of this beam as it scanned the room coupled with the video data is put into a Python script, which outputs a point cloud of whatever is scanned. In this manner he is able to get full real-time scans of entire rooms. Fortunately for us, he’s provided extensive documentation on his homepage.
