3D Printing: 3D Scanner

New! 3D Scanning Available

The HPD Library now has a David Systems SLS-2 3D Scanner available for use.

3D scanners create a 3D computer image of a physical object.  Those images can be edited and printed on a 3D printer.  

The David SLS-2 consists of a projector, a camera, a tripod (or mounting arm), software, a turntable, and calibration plates. Structured light scanning projects a pattern of light and shadow on an object. The camera reads distortion in the light pattern as it is projected onto the object, and the software converts those distortions into an image.  The object is rotated on the turntable to capture all sides of the object.  The software merges all the images into a 3D representation of the object, which can then me exported into a variety of software formats, including .stl files for 3D printing.  

The scanner is a high-end technical device.  It requires some set-up and calibration for good results.  If you watch and follow the tutorials, you should beady ready to scan in less than an hour.
