Tethon 3D Launches Castalite Investment Casting Resin for Stereolithography

Tethon 3D, one of the leading innovators in ceramics 3D printing, is launching a new resin material for 3D printing. The material, Castalite, is a photo-curing ceramic polymer resin for use in SLA or DLP printers. Following kiln firing, objects printed with Castalite are suitable for use as a ceramic shell mold in metal casting processes. The new material has very high heat and thermal shock tolerances that make it ideal for use in casting many metals such as bronze, gold, silver, and aluminum.

“Castalite adds another premium material to our product catalogue that compliments the growth seen in SLA and DLP hardware”, says Karen Linder, President and CEO of Tethon 3D. “Recent improvements in 3D printer technology provide higher resolution details in the casted metal part and faster print times. Most printers can print at 25 micron print layers and Castalite demonstrates excellent resolution at that level.”

Molds with a sprue and gate are 3D printed directly in Castalite, followed by high temperature furnace firing. This produces a ceramic shell model ready to accept liquid metals. An advantage of using this material to directly print a mold is the elimination of a wax model or other pre-mold steps, as in traditional casting techniques. The Castalite process increases the speed of production and decreases the quantity of material used, resulting in a cost reduction.

Industries with applications for Castalite include traditional and advanced manufacturing, engineering, jewelry and others.

Tethon 3D manufactures all its products in the United States and distributes to over 40 countries globally. Full product range includes resins and powders for SLA, DLP and powder/jet binder 3D printing. Additionally, the company provides service in 3D modeling, scanning and ceramic 3D printing, as well as 3D printing educational workshops and a residency program.
