Prime Negatives: Parametric Sponge-Forming and Slip Casting for Ceramics

Prime Negatives: Parametric Sponge-Forming and Slip Casting for Ceramics

Weston, Mark

Article:

Traditional methods for slip casting require the creation of prototype “patterns” for the making of molds. Computer modeling, however, can be understood to produce virtual positives, thereby suggesting a CNC production focused on the creation of negatives, or molds, without the need for a physical pattern. Three experiments in slip casting for ceramics are examined as a means of producing production parts without first making prototype patterns in the positive. Two techniques leverage computer modeling and CNC tools to directly produce formwork for casting positives, while the third technique uses a lost positive formwork for production of the final part.
