Precautions:■

■

■

TCaST is strongly alkaline on contact with water or moisture including sweat and tears and may cause irritation to the skin, eyes or respiratory system or inflammation of the mucous membranes.Do not get TCaST into your eyes. When it gets in your eyes, immediately wash thoroughly and consult an eye doctor.Do not get TCaST on your skin.

3D printing with TCaST

Advantages of TCaST ®

Examples of castings

TCaST® is an inorganic powder material for binder jetting 3D printers.Casting molds and cores can be directly 3D printed using TCaST®, which provides ever faster metal casting processes. The combined technology of TCaST® and 3D printers will find wide applications, including molds for high-temperature molten metals and various special molds with complicated shapes that have been impossible with conventional casting patterns.

TCaST ® can be applied to a wide variety of castings, ranging from industrial products to traditional crafts.

・

・

・

Quick turnaround time is possible with the molds directly modeled from drawing data.No casting patterns are required, which provides ease of modification.Molds have high early strength that allows immediate use after building.

・

・

Almost no offensive odor occurs. Clean environment can be achieved without any additional investment for better working conditions or pollution control.Gas generation is small, which creates smooth casting surface.

・Molds made of TCaST® show high bending strength during handling, and yet ensures easy shakeout after casting.

・

・

TCaST® can be applied to high temperature casting that has been impossible with conventional gypsum.TCaST® has a low coefficient of thermal expansion that allows for high precision making of molds.
