Dear MEL Topic Readers,
World's biggest 3D printer whirs into action
3D printing creates three-dimensional objects layer by layer from a computer-aided
design (CAD), or a digital 3D model. One of the key advantages of 3D printing
is the ability to produce very complex shapes or geometries that would be
otherwise infeasible to construct, including hollow parts or parts with
internal truss structures. Since 3D printing uses only the material needed to create
an object, it also reduces material waste. Materials used for 3D printing
include polymers, metals, and ceramics. It is used for producing prototypes for
automotive, aerospace, and electronics, customized products including medical devices,
prosthetics, and dental implants, and even architecture and construction with
concrete and composite materials. Last month, the University of Maine, USA introduced
the world’s largest polymer 3D printer that could print a 29-meter-long house
by itself. When recycled polymer or residual wood is used as material to feed
into the printer, it’ll produce more eco-friendly houses.
