3D scranner

cults3d

Ever since I got my 3D printer, I've always wanted to create a 3D scanner of my own. I've already used an Xbox Kinect sensor to scan objects into my computer, but it's only suitable for large items, rooms, or people. I've also tried using 123D Catch with images, but it can be challenging to get a good scan without a turntable set up at precise angles. To create the scanner I need, I'm using a laser that shines on the object from different sides. This approach comes with its own set of challenges, but it might work for my specific needs. With this method, I'm scanning objects into my computer using a SLR camera and software like 123D Catch or Horus. Two laser lines are projected onto the object to help the scanner capture accurate data. The turntable is powered by a NEMA 17 stepper motor that spins at precise angles. All the components – lasers, stepper motor, and Arduino board – are controlled from beneath the scanner. The Arduino UNO controls everything with input from either my computer or a button that lets me rotate the turntable to different positions.
