Kastbare

Kastbare is a modular design concept centered on rapid casting of parts using standardized mold blocks and interchangeable base components. The approach emphasizes interoperability, low tooling costs, and iterative prototyping, allowing designers to produce and refine parts without custom tooling for each iteration.

The name Kastbare combines references to casting and openness in design, signaling a system built around castable materials and open interfaces between molds, cores, and finishing components.

At the core are mold blocks with standardized connection interfaces, a base frame to hold parts, and a selection of castable materials such as resins, silicones, or low-melting alloys. The blocks form a scalable, reusable mold array that can be reconfigured for different geometries.

During production, designers assemble the mold array, mix and pour the chosen castable material, allow curing, and demold. Finishing steps may include trimming, smoothing, or painting. The process supports rapid iteration, with changes implemented by reconfiguring mold blocks rather than fabricating new tooling.

Applications include product prototyping, educational demonstrations, hobbyist manufacturing, and small-batch production. Advantages include reduced lead times, cost savings, and reuse of components; drawbacks can include limited surface finish, material constraints, and the need for safe handling of resins or metals.
