Since 3D printing was first developed in the 1980s, the technology has come a long way, allowing people to create product prototypes, machine parts, prosthetics, art and more. At MFL MarMac, it’s become a unique and engaging resource in the high school’s industrial technology classes.
Also referred to as additive manufacturing, 3D printing involves creating a three-dimensional, solid object from a digital model. Through an additive process, objects are formed as a printer continually distributes thin, horizontal layers of a material, one on top of the other, until the desired object is complete. This is unlike the single-layer, two-dimensional images formed with regular desktop printers.
