  • Silica Sand
    Silica sand is one of the most common varieties of sand in the world and is derived from quartz crystals. It is used for a wide range of applications, including the creation of molds and cores for industrial castings. The advantage of using a common material such as silica sand for 3D printing is that it requires no changes at the foundry. Additionally, when used with furan binder, it is considered a “no bake” product, which means that printed silica sand molds and cores are immediately ready for casting.

            • Ceramic Beads
              Ceramic Beads is a spherical ceramic (synthetic) sand used in foundry operations for the creation of sand molds and cores. It is comprised of aluminum silicate and exhibits excellent refractory properties, high permeability and low thermal expansion. Gases are readily dispersed, reducing the potential for porosity in the casting. Cerabeads is compatible with all binders and is especially recommended for casting steel alloys or printing cores subject to high thermal stress conditions.
              • IN Alloy 625
                ExOne® 3D Printed Alloy IN 625 material is a nearly full dense, austenitic nickel-chromium-based superalloy. This material offers excellent mechanical properties both at extremely high and low temperatures. It also exhibits high resistance to oxidation at elevated temperatures of up to 1050°C. Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts with high heat transfer capabilities.

                • IN Alloy 718
                  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 / Bronze Matrix
                    ExOne® 3D Printed Iron infiltrated with Bronze is a matrix material composed of 60% iron and 40% bronze infiltrant. This material offers good mechanical properties, is able to be machined, welded and polished, and offers excellent wear resistance.

                    • Iron-Chrome-Aluminum
                      Offering superior properties as compared to the other alloys, Iron-Chrome-Aluminum alloys are widely used in electrical furnace, electrical oven, home appliance, electrical heater and infrared settings.
                      • Bonded Tungsten
                        Developed in partnership with an ExOne customer, bonded tungsten has been qualified for use on the M-Flex 3D printing system. 3D printed bonded tungsten is an effective replacement for lead in the medical imaging and aerospace markets, and as such, it is a great solution for protecting people and their environments from the harmful effects of ionizing radiation.
                        • Tungsten Carbide
                          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.
