  • 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.

                    • 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.
                      • Chromite
                        Chromite sand is a naturally occuring spinel consisting of chrome and iron oxides. As a mold and core making sand, its properties enable the material to be utilized in heavy duty grey iron and steel foundries. Its high thermal conductivity gives it favorable chilling properties and low thermal expansion contributes to excellent dimensional stability. Used as a standalone material, or as an additive to silica sand, chromite allows for faster heat dispersion and results in finer microstructure of the metal and therefore a higher quality casting.

                        • Cobalt-Chrome
                          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.
                          • Zircon
                            Zircon (a naturally occurring beach sand) is often used in foundries for the production of sand molds and cores to improve casting performance. It has a high thermal expansion coefficient, a melting point of 2500°C, and a Mohs hardness of 7.5. Zircon’s low thermal expansion rate, its high thermal conductivity and its non-wettability by molten metal make it and ideal mold and chill sand. It is also used to improve surface finish. Zircon can be 3D printed as a straight material or as a mixture with silica sand. Its usage as an additive creates faster heat dispersion and results in finer microstructure of the metal and a higher quality casting.
