Introduction:

Taking layering as a technique to make 3d form by depositing grey cement as a material

Intent:

Nowadays The term "3D printing" can refer to a variety of processes in which material is deposited, joined or solidified under computer control to create a three-dimensional object, with material being added together (such as plastics, liquids or powder grains being fused together), typically layer by layer.

This set of experiment is the attempt to make same desired 3D form at domestic level not by using digital tools. here the technique of layering is manual therefore the force and the density of the material is controlled.

Material :

Grey cement is the only material used for depositing layers.

Tools:

plastic piping bag

Experiments:

1) Experiment with grey cement. Taking steel bowl as a base mold in order to obtain the same shape through layering.

• take a bowl and apply oil on the surface.

• mix grey cement and water.

• Pour the mixture in piping bag.

• Deposit the mixture slowly through the piping bag with the desired line weight.

Observations:

• since the force applied is manual to deposit the material line weight is unequal.

• Process has to be done rapidly because the mixtures start drying faster.

• pattern lines get mixed if water content is higher also it becomes difficult to deposit material if water content is lesser.

• cracks are observed if water content is higher.

• it takes minimum 4 to 5 hours to dry.

2) Experiment with grey cement. Taking steel bowl as a base mold in order to obtain the same shape through layering.

• take a bowl, cover it with plastic sheet and apply oil on the surface of the plastic sheet.

• mix grey cement and water.

• Pour the mixture in piping bag.

• Deposit the mixture slowly through the piping bag with the desired line weight.

• add layers to it.

Observations:

• since the force applied is manual to deposit the material line weight is unequal.

• Process has to be done rapidly because the mixtures start drying faster.

• pattern lines get mixed if water content is higher also it becomes difficult to deposit material if water content is lesser.

• it takes minimum 4 to 5 hours to dry.

• since the bowl is covered with plastic sheet it becomes easy to demould the form.

3) Experiment with grey cement. To obtain a form without taking any base mould.

• mix grey cement and water.

• Pour mixture in a piping bag.

• decide the form.

• use hair dryer to dry the top layer so that the next layer wont get merge with the bottom layer.

• the process needs to be litter faster.

• Then layer the pattern and dry it simultaneously.

Observations:

• if the water content is higher than the layers start to merge within themselves.

This experiment in domestic stage opened the possibilities to make defined objects through the process of layering.
