From 3D printer to wearable light tracking! Posted on March 14, 2014 by Gary Martin The print process begins with a computer model of the part. This is the 126th iteration! 3D printing creates shapes layer by layer until a fully formed object is complete. Printed textures can appear almost fabric like. Slowly the case form rises from the build platform. Multiple objects can be printed on the build platform at a time. Light tracking electronics fit snugly inside the enclosure. Flexible materials need to be printed slowly to maximises strength and finish. Each case takes about 40min to print. The flexible white case is 31mm x 31mm x 21mm (WxHxD). Folded closed, the four sensors (red, green, blue, and clear) align with case openings. RGB colour gels are added later for each sensor. A serial data connection is accessible from below. On the back a magnetic clasp holds the case closed or can be used to clip to fine materials. An optional mechanical clip allows attaching to thicker items such as jackets, coats, scarfs and bag straps. Keep repeating!
