The process is called Additive Layer Manufacturing, and it works somewhat like a 3-D printer.

这种加工工艺叫作加层制造法，其工作原理有些类似三维打印机。

Products are thus built up by progressively adding material, one layer at a time: hence the technology's other name, additive manufacturing.

添加材料一次一层、步步为营直至成形，因此该技术又有了另一个名称：加法制造。

Products are thus built up by progressively adding material, one layer at a time: hence the technology’s other name, additive manufacturing.

产品就是这样通过一层一层地叠加材料制造出来。这种技术于是被人称为“叠加式制造”。
