Linear Mold helps Michigan teen design, build watch using additive manufacturing

The possibilities of the additive manufacturing (3D printing) process are almost endless when it comes to making end-use products. Just ask Elbert Han, a 15-year-old student at Detroit Country Day School’s Upper School. A class in jewelry and metals with teacher Jiro Masuda introduced Han to CAD systems and he began designing jewelry using Google Sketchup, but eventually graduated to SpaceClaim, explained Han, who is now 17 and recently won an award for his 3D-printed watch.

Han’s first experiment with Direct Metal Laser Sintering (DMLS) was “a bit disappointing,” he said, because the surface was quite rough and contained bronze, which turns skin green. “That was definitely unsuitable for jewelry, and I turned back to the high-detail resin.”...
