Mouldcast Studio earns its place in the superhive library for turning repetitive mold modeling into a procedural step, with an MIT license and direct STL export that fits into 3D-printing and casting workflows.
Mouldcast Studio is a procedural mold generation add-on for Blender aimed at makers working with casting workflows. It converts a 3D object into a complete mold structure ready for fabrication. Rather than manually modeling mold halves, planning seams, and building block geometry, the add-on generates the mold automatically while keeping everything fully adjustable. You load an object, define the mold parameters, and generate a mold system in seconds.
The generated mold parts export directly as STL files for 3D printing, and can be used to produce molds for materials such as ceramics, plaster, resin, wax, or silicone. Adjustable controls cover the number of mold parts, procedural block generation, alignment keys for accurate assembly, an optional pouring hole system, and base structure. A visual separation preview lets you inspect the mold before exporting.
Because mold creation becomes a procedural step, it suits producing prototypes, variations, or small production series. Mouldcast Studio runs as a Blender add-on and requires Blender 4.5 or greater; basic familiarity with Blender is recommended.
Mouldcast Studio is best for makers producing molds for casting workflows, including ceramic slip casting, candle molds, resin casting, plaster molds, silicone master molds, craft production, and small product manufacturing, as well as prototypes, variations, and small production series.
Mouldcast Studio is completely free to download and use.
Mouldcast Studio requires Blender 4.5 or greater and is listed as compatible with Blender versions 4.5 through 5.0. It is distributed as a Blender add-on, and basic familiarity with Blender is recommended before using it. Versions below 4.5 fall outside its stated range, so it targets recent Blender releases only. If you are running a version within the 4.5 to 5.0 range, you should be able to install and use the add-on. Check the developer's page to confirm the details for your specific setup.
Mouldcast Studio produces mold parts that can be used to produce molds for materials such as ceramics, plaster, resin, wax, or silicone. The developer lists typical applications including ceramic slip casting, candle molds, resin casting, plaster molds, and silicone master molds, along with craft production and small product manufacturing. That range makes it applicable across a variety of casting workflows. For specifics on any particular material or workflow, refer to the developer's documentation for further guidance.
Mouldcast Studio exports the resulting mold parts directly as STL files, which are intended for 3D printing. The workflow runs from selecting the object you want to cast, generating the mold system, adjusting mold parameters if needed, inspecting the mold with the separation view, and finally exporting the parts as STL files to print and produce the mold. The developer's page covers the full step-by-step process.
Mouldcast Studio is listed as free in this catalog, and it is distributed under the MIT license. Licensing terms can change over time, so it is worth checking the developer's page for the current details before relying on it for a project. The MIT license is a permissive open-source license that the developer has assigned to this add-on. For any questions about usage rights or redistribution, the developer's page is the best place to confirm the latest terms.
