3D Printed Sacrificial Tooling —Washes Out with Water
ExOne's unique Washout Tooling solution streamlines the production of aircraft ducting, pressure tanks, struts, mandrels and other hollow tools and objects. The process is simple: We 3D print the tool core in silica or ceramic sand, and coat it with a proprietary material that remains water soluble to high temperatures. Then, composite layup is completed as normal. After autoclaving, the entire tool is simply washed away with water, and the sand is reclaimed for reuse.

3D Print. Coat. Layup. Rinse & Repeat.
ExOne 3D prints your tool in sand, and coats it in a proprietary material. You lay up carbon- or glass-fiber parts on the tool as normal, autoclaving up to temperatures of 180° Celsius or 356° Fahrenheit. When complete, the sand tool washes away with tap water. Sand can be reclaimed for reuse.
