3D-Printed Christmas Tree Ornament
The ornaments on a Christmas tree could soon be 3-D designs. Scientists at the Additive Manufacturing Lab at GE Global Research in Niskayuna, NY are creating ornaments through 3-D printing.
This video explains the process of 3-D printing, also called additive manufacturing, used to make the design. Additive manufacturing builds up material using layers on other layers. This avoids the process of forging, casting and using large manufacturing machines to build an object. The process has three main ways to create an object: scientists can use a laser to create a base layer and then add layers, use aerosol jets to direct material into a shape, or use electron beam melting to create metal objects. Scientists believe additive technology will replace much of traditional manufacturing in the future.
