3D Mold Making

Example of a cement relief cast of a life-size bee.

 

Course outline:

In this course, participants will be introduced to two basic mould making techniques namely plaster waste molds for cement casting and flexible silicone rubber molds that multiple materials can be cast in. No previous experience is needed and a brief visual presentation will provide participants with the necessary background and examples. The course will be divided into two parts:

  1. Making a plaster waste mould for a cement relief.

In this first part of the course participants will learn how to make a relief portrait out of clay and then make a plaster waste mold around it. The relief will be about the size of an A4 piece of paper. After the plaster has set the clay will be removed and the mold cast in cement.

  1. Making a flexible re-usable, silicone mold for multiple materials.

In this section participants will learn how to make a flexible silicone mould of an object of your choice. Bring along an object that is not too complicated and no larger than your fist. Once the mold has been completed, participants will be able to cast a variety of materials, for example, plaster, wax and cement into the mold.

 

 

What you will need:

 

The basic materials that you will need for this course will be provided at a cost of R200 per participant. These include; plaster, cement, wax, silicone.

In addition please bring along the following:

  • 2 x plastic ice cream containers

  • 1 x pair of plastic gloves

  • A high resolution photograph for the relief portrait. (This can be human or animal)

  • A sketch pad and drawing materials of your choice.

  • An Object of your choice for the silicone mould (not to complicated and no larger than your fist)
