Salty Rice Clay

By Michelle Tseng | Published: October 21, 2014

MATERIAL DESCRIPTION

Salty Rice Clay made by equal- ratio mixing salt and Thai glutinous rice at room temperature.

The glutinous rice creates the super-strength mortar, this organic-inorganic compound was made possible by amylopectin, a type of polysaccharide, or complex carbohydrate. The amylopectin combines with the inorganic calcium carbonate from the lime to form a mortar that has more stable physical properties, greater mechanical strength. It has been found more stability by adding the salt (sodium chloride) with glutinous rice to creat a material with ductility, but also the ability to maintain a certain shape.

 

EXTRACTION PROCESS

Polyester (Organic)

By Rossana Graca | Published: October 20, 2014
Polystyrene - The Fibre

Polystyrene – The Fibre

Scientific Name: Poly(ethylene terephthalate)

Formula/ Chemical Composition: C10H804

It is made of many substances that contains compounds derived from living matter, making the material organic. Its biochemical composition thus consists of highly polymerized esters of fatty acids that are waxy and water repellant substances in plant cuticles, called Cutin. To put it simply, it controls the movement of water, solutes and gases. Living matter (e.g. plants) depend on these barriers that provide an interface with the environment. Furthermore, the main ingredient is a derivation of petroleum, called ethylene.

Material Description: The object of study is a mosquito net which is made from polyester, sometimes referred to a Terylene if it is used as fibre. A mosquito net is a net that usually hangs across a door, a window or around a bed to keep mosquitoes away in most tropical and hot climate, preventing the increase of diseases such as malaria, dengue fever, yellow fever amongst others. Polyester is a good material to fight against mosquitoes and other insects because it is small enough to exclude the insects without preventing the passage of air into a place, nor impeding the ability to see. In addition, if it is treated it is more effective in the prevention of tropical diseases. Read More »

Stretched Mesh Steel Plate

By Raissa Pertierra | Published: October 18, 2014

stretched mesh steel plate  Stretched Mesh Steel Plate

FORMULA 

Fe + C

MATERIAL DESCRIPTION

Steel is an iron-carbon alloy (from 0.1 to 2.1 percent). The steel plate is used to construct caps, boxes, fittings, reflectors, surface coating and as a protector and furniture in areas where heat radiates.

It is difficult to establish the physical and mechanical properties of steel because these vary with the settings in their composition and the various thermal, chemical or mechanical treatments, which can be achieved steels combinations suitable for many applications characteristics, there may be mentioned some generic properties:

• Its average density is 7850 kg / m3.

• Depending on the temperature the steel can contract, expand or melt.

• Very tough, especially in some of the alloys used to make tools material.

• Relatively ductile.

• It is malleable.

• Allows good machinability on machine tools before receiving heat treatment.

• It can be welded easily.

• Corrosion is the biggest disadvantage of steel as iron rusts with ease by increasing its volume and causing surface cracks that allow the progress of oxidation until piece completely consumed.

 

EXTRACTION PROCESS

The stretched netting consists of a metal plate with holes in a diamond pattern. These voids are created without wasting material because it is made with a tool that presses and stretches the material at the same time without soldering

ADVANTAGE IN THE CONTEXT OF DIGITAL FABRICATION

• The mesh is formed from a single piece of metal, there is no joint, or welds.

• In the process there is discarded unlike other treatments as drilling.

• higher strength-to-weight is obtained that the sheet metal.

• a non-slip surface through the edges is generated.

• It is a very efficient conductor

• It has excellent resistance to corrosion

• Variety of meshes with different sizes of the diamond

Cork Oak (Quercus suber)

By James Mitchell | Published: October 17, 2014

cork 01

FORMULA/ CHEMICAL COMPOSITION

C123H182O56N

MATERIAL DESCRIPTION

Cork is the external protective layer of dead cells (known as bark) on an evergreen Cork Oak tree (Quercus suber).  The bark is composed of cells consisting of a gaseous composition similar to air particles, combined with layers of cellulose and suberin. The Cork Oak tree grows in the Mediterranean, particularly in Portugal and Spain.

EXTRACTION PROCESS

The harvesting process is achieved by stripping the bark off of the tree during the spring and summer seasons every nine to ten years, using a traditional cork axe.

ADVANTAGE IN THE CONTEXT OF DIGITAL FABRICATION

Cork is a strong and light material that can be easily manipulated through digital fabircation. Due to its low desnity, it can be easily cut using a laser cutter or milling machine into a variety of forms. The waste it produces can be recycled and re-used for different digtial fabrication designs.

The lamps are hand-turned out of Portuguese agglomerate cork blocks and created using waste cork from wine stopper manufacturers.  The left over waste is fed back into the process and used to produce the next bunch of lamps.
