During the laser-aided additive manufacturing process, the researchers fired a beam from an infrared laser to form a melt pool on the substrate surface.

在激光辅助添加制造过程中，他们发射了一个红外激光束，在基板表面上就形成了熔池。

The process, known as additive manufacturing, allows the powder form of metals to be melted and then fused together into objects using a laser.

的过程中，被称为添加剂制造，允许金属的粉末形式可以熔融，然后熔合在一起成为使用激光的对象。

Ott immediately thought of an additive manufacturing process called direct metal laser sintering (DMLS) that she had encountered in her work at a major aerospace company.

Additive manufacturing can also be achieved by a number of other methods, such as selective laser sintering (SLS).
