3D models for plaster moulds

March 12, 2023

Slip casting is a ceramic forming technique used by studio potters as well as in manufacturing or factory settings. The process from idea to finished work starts with designing a model. Once there is a blueprint, our team in Relyef can help the artist transfer the drawing into the 3D printed model and possibly into a plaster mould.

Thanks to our collaboration with potters we are still improving the possibilities of supporting your ideas and creations.

The vase, tea jar, and Christmas ornaments described below are examples of such cooperation. The artist came to us after she made her prototypes and drew the blueprint with measurements.

We transferred each drawing to an .stl file necessary for 3D printing. When creating the file, there needs to be a plan for how the model will be cast into the mould. The project includes which parts will be moulded separately and if and where to cut the model to allow easy moulding. It is also wise to consult the model with the plaster mould master before making the mould - even though almost everything can be moulded, it is crucial to consider the model parameters, especially in complex forms.

The possibilities to produce the best 3D model for plaster casting evolved with time. You can see below what quality we have started with and our current production. Our models do not need to be retouched anymore.

Once the model is ready, we take it to a plaster mould master. After the consultation with the plaster mould maker, the mother mould is made, the artist tests follow, and then the production moulds are made. The mother mould will allow for making more production moulds after they are worn out.
