Revolutionizing Ceramics with 3D-Printed Slab Molds: A Clean Break from Traditional Slip Casting

Traditionally, slip casting in ceramics can be a messy process, involving intricate plaster molds and liquid clay. However, [Allie Katz] introduces an innovative approach by leveraging 3D printing technology to create slab molds. This technique combines the precision of 3D printing for intricate designs with the malleability of clay, offering a cleaner and more efficient way to produce reproducible clay objects.

[Katz] provides insights into the process of “Mould Making 101” before delving into the creation of slab casting press molds. The positive CAD design serves as the starting point, with a focus on eliminating undercuts and facilitating air infiltration—an essential consideration given that a plastic mold lacks the water-absorbing properties of a plaster mold. Additionally, custom-designed cookie clay cutters aid in handling more complex geometric shapes. After the 3D printing phase, the molds are coated with cornstarch, and clay is pressed in. Following removal, final touches like handles can be added, and the pieces undergo standard firing procedures.

For those intrigued by the fusion of 3D printing and ceramics, this method offers a departure from conventional slip casting, showcasing the potential for cleaner and more streamlined production processes. Explore further intersections of 3D printing and ceramics with innovations like 3D-printing glass with a laser, reliable ceramic slurry printing, or alternative TPU-based approaches.
