ExOne Introduces Six New Materials for Their 3D Printing System

Manufacturer of Binder Jetting 3D printing systems, ExOne, has announced six additional materials for the company’s proprietary systems: Cobalt-Chrome, IN Alloy 718, Iron-Chrome-Aluminum, 17-4 Stainless Steel, 316 Stainless Steel and Tungsten Carbide.

“ExOne developed the latest printable materials for our binder jetting process as a result of our expanding customer development programs,” explained Rick Lucas, ExOne’s Chief Technology Officer. “Utilization of these materials in ExOne’s machines will allow our customers to advance our binder jetting applications with their technologies. The diversity of this group of printable materials demonstrates the breadth of industries that ExOne touches, including the aerospace, automotive, energy, foundry and medical markets – broadening our addressable market.”

Cobalt-Chrome (Co-Cr) is traditionally used in various fields where high wear-resistance is needed, including aerospace, cutlery, bearings and blades, Cobalt-Chrome alloy has recently received more attention for medical applications due to excellent resistant properties, high melting points and incredible strength at high temperatures.

IN Alloy 718 is commonly used for components in the aerospace, chemical and energy markets, with applications including gas turbine blades, filtration and separation, heat exchanger and molding processes, the alloy is desirable due to its oxidation and corrosion-resistant qualities, able to retain its strength even when subjected to extreme environments.

Iron-Chrome-Aluminum (FeCrAl) offers superior properties as compared to the other alloys and is widely used in electrical furnace, electrical oven, home appliance, electrical heater and infrared settings.

17-4 Stainless Steel and 316 Stainless Steel both have broad applications in the automotive, medical and general industry markets, used to produce a range of products, including surgical tools, metallic filters, pumps, impellers and structural automotive parts. Both grades are known for their excellent mechanical and corrosion resistance properties and cost-effectiveness.

Tungsten Carbide (WC) is one of the hardest carbides with a melting point of 2770°C, Tungsten Carbide is mainly used in the production of high wear-resistant abrasives, carbide cutting tools (knives, drills and circular saws), and milling and turning tools used by the metalworking, woodworking, mining, petroleum and construction industries.
