Experimentation with various material mixtures of clay, mud, cement etc. The intent was to study patterns, textures and forms created by the acts dropping the mixture from an apparatus or pre-defining a path of deposition, with the intent of exploring a manual method of 3D printing.
STENCIL PRINTER
How can the technique of dropping develop new methods of designing and making a form?
About Experiment
INTENT: Continuing a study from a previous studio work which looked at the idea of a unit formation through natural processes and how it gets shaped and the geometry that it follows. The method explored, in this study, to understand this principle is through the technique of dropping. Mass of material when dropped under gravity, acquires a certain texture and form as we see in the process of making a cob wall. Using this principle, an apparatus is enabled to make a 3D form by understanding and using the method of dropping units for different material mixtures.
AIM: To understand how different proportions of
1- Cement, Sand and Water
2- Mud with maximum proportion of clay with water
3- Mud with less proportion of clay with cement and water
behave when dropped under gravity using the same apparatus.
METHODS:
1-Exploring densities and viscosity of the three materials.
2-Setting up an apparatus that allows change in dropping height.
3-Dropping the material masses of the same size from different heights.
MATERIALS :
Mud, Cement
APPARATUS:
LEARNINGS:
Through multiple experiments, the behavior of cement, mud and a combination of the two were observed. Cement because of its fast reaction with water has to be kept in a continuous mixing motion to maintain its viscosity. Since we were not able to achieve this because of the manual operation of the apparatus, the mixture of cement, sand and water in any proportion does not work.
Mud having less clay content requires a small percentage of cement to hold its form. Increase in this percentage, makes the form brittle and develops cracks after drying.
Experimenting with a different soil type having more clay content could hold its form without developing cracks after adding water to it.
EXPERIMENTS:
Attempt 1 : Different Proportions
Attempt 2 : Different Heights
How can we make an apparatus that works on a logic of a 3D form with more human involvement in the process?
About Experiment
INTENT: A 3D printer is a tool that allows making of products through codes and programs. This programming sets a path for the nozzle to move and deposit material, thus forming the product. However, the involvement of human agency is limited to the input stage.
The intent is to make an apparatus that works on a similar logic of having a defined path to make a 3D form, but requires more human involvement in the process of making which makes it more t. The movement of the nozzle is mechanized, thus requiring an instinctual understanding of how much force is required to move it. It also requires an understanding of material viscosity as the pressure to be applied varies with each material. These aspects allow a physical connection with the process of form making.
The principle of working is inspired by spirograph, in which a circle rotates along the inner circumference of a larger circle with a fixed point that defines the path. The intent is to create a 3D form by defining a path along which the material is deposited to make the form.
AIM:
To understand the logic of making a defined path and making a mechanism to recreate that path.
MATERIALS ;
Cement, Glass Fiber
METHODS:
Exploring viscosity of cement with additives to get a continuous flow of material.
Gear Mechanism to rotate the discs to have a defined path.
Different outlet points offsetted from the center of the circle to have different paths.
