en cities around the world and carrying machine components,” noted Mohammad Ehteshami, the former head of engineer

ing at GE Aviation who now runs GE Additive, a new business focusing on the latest manufacturing techni

ques like 3D printing. “Tomorrow, you won’t need to do all of that. You’ll just print what you need.”

At Siemens, additively-manufactured turbine blades can be cooled by complex internal channels, thereby improving their fun

ctional efficiency. Such technology now allows novel geometries that were not possible before.

According to a report released by the German conglomerate, add

itive manufacturing enables rapid prototyping resulting in up to 75 percent of former develo

pment time, and is more sustainable by consuming up to 65 percent less resources, by reducing gas emiss

ions by up to 30 percent and generally by creating components with longer life spans.

Experts believe that China is quickly closing the gap on the technology’s application and commercialization.
