Sphere_laser cutting

Laser cutting time – 14 minutes.

Size of the sheet – 68×36 cm

Size of the spheres – 12 cm in diameter

Sphere_strategy 1

We divided sphere into 10 equal slices by cutting the sphere with radial planes, after that  we applied twisting to these slices by 60 degrees. By unrolling surface of the slice we were able to have 2D element on which we made joints suitable for flexible material such as polypropylene.

Sphere_strategy 2

The second sphere was created by dividing sphere into 12 equal slices, also done by cutting the sphere with radial planes. Here, we experimented with folding detail on two points of sphere where slice sheets meet.

TECHNICAL SHEET

Transparent Epoxy Resin

Transparent Epoxy Resin

MATERIAL: Epoxy Resin.
SCIENTIFIC NAME: Polyepoxide (epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A.)
Formula: C21H25ClO5
MATERIAL DESCRIPTION: Epoxy or polyepoxide is a thermosetting epoxide polymer that cures (polymerizes and crosslinks) when mixed with a catalyzing agent or “hardener”
In general, epoxies are known for their excellent adhesion, chemical and heat resistance, good to excellent mechanical properties and very good electrical insulating properties.

BASIC PROPERTIES

SCIENTIFIC NAME: Fiberglass – Glass-Reinforced Plastic (GRP)

FORMULA/CHEMICAL COMPOSITION: (SiO₂)_n

MATERIAL DESCRIPTION:

Fiberglass is a strong lightweight material and is used for many products. Although it is not as strong and stiff as composites based on carbon fiber, it is less brittle, and its raw materials are much cheaper. Its bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes. Applications of fiberglass include, aircraft, boats, automobiles, bath tubs and enclosures, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards, and external door skins.

EXTRACTION PROCESS:

The process of manufacturing fibreglass is called pultrusion. The manufacturing process for glass fibers suitable for reinforcement uses large furnaces to gradually melt the silica sand, limestone, and other minerals to liquid form. It is then extruded through bushings, which are bundles of very small orifices (typically 5–25 micrometres in diameter for E-Glass, 9 micrometres for S-Glass). These filaments are then coated with a chemical solution.

BASIC PROPERTIES:  (e-glass)

Tensile Strength: 3445 (MPa)

Compressive Strength: 1080 (MPa)

Density: 2.58 (g/cm³)

Thermal Expansion: 5.4 (µm/m·°C)

3D Printing: used as filament

Recyclable

Low CO2 footprint
