| ExOne’s 3D printed X1 Metal 316i™ is a matrix material composed of 60% 316 steel infiltrated with 40% bronze. The lower yield strength of the material enables it to be easily machined and polished. This material also exhibits enhanced corrosion resistance properties. Applications: This material system has low magnetic properties which makes it particularly useful for applications in the food and medical industries. The copper alloy acts as a natural antibacterial agent making it easy to decontaminate printed parts. Since the matrix material is easy to polish, additional applications exist in bath and kitchen hardware prototypes and low volume production. Composition:
Stainless Steel: Alloy 316
Bronze: 90% Cu / 10% Sn Printing: Using binder jetting technology, ExOne’s state-of-the-art 3D printing machines produce parts directly from 3D CAD models by precisely controlling the jetting of binder onto a powder bed, and then subsequently spreading new layers of powder. This process is repeated until the part is completed. This 3D printing process offers increased design flexibility, reduced manufacturing cost and shortened lead times. Post Processing: After printing is complete, the parts are cured in an oven, which enables the parts to be handled. After curing, the parts are sintered and infiltrated with bronze above 1100°C. Cool down can be varied to control the machinability and hardness of the material. Information provided by ExOne™ |
