Additive Manufacturing
Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.
不锈钢
■ 工艺简单、成熟，适于推广、研发成本低
■ 粉末成型性好、后续加工工艺简单，适用范围广
■ 典型合金：316L、17-4PH等
316L、17-4PH为代表不锈钢是MIM工艺的主要材料
