ging, cutting and polishing, around 90 percent of the metal is scrap and only 10 per-
cent remains. The opposite is possible with metal 3D printing - 90 percent remains
in the part and 10 percent is scrap.

· Size if small

Microstereolithograpy or laser lithography are used to produce micro and nano
structures in microscale fabrication. The smaller the object the faster the printing
goes. A microscopic object might only take seconds to print (see Nanoscribe page).
Small size is also beneficial considering the high materials cost connected to 3D
printing. Smaller build chambers might also mean cheaper machinery.
