During the milling process used a zinc thickness of 1 millimeter. The design is reflected in the creation of 2D file which bending procedure would  assume 3d shape of a sphere, and as such is designed as a small table lamp that had four legs, central / inner part with a hole for the possible installation of lighting and eight side portions to form a spherical shape.

During this process there has been a mistake when setting the controls in RhinoCam, where small contiguous parts were cut from the outside insted  of cutting from  inside so that the main holders were torn during this process. On the other hand, it is noted that the material behaves very well during this process, particularly for large parts, leaving a very accurate curvature  and clean forms.

3d printing covered the design of small joints of powder. The exercise was designed to study the possibilities of connecting elements in the x, y, z axis using a single type of connector where you can connect elements only at an angle of 0 degrees or 90 degrees. By rotating these elements can be obtained very interesting shapes. On the other hand, as a result is obtained very fragile connectors and it was necessary to strengthen them with glue.

During the cutting exercise was used natural wood with thickness of 3mm. Design sphere included interconnecting 3  horizontal circular area with 12 vertical “slices” using method of slits with offset of 0.5 mm according to the thickness of the material.  As a result of the exercise, obtained a very compact, solid sphere  without need for  using glue or other linkers.

FORMULA:

Zinc (Zn)

MATERIAL DESCRIPTION:

Zinc  is a chemical element with symbol Zn and atomic number 30. It is an essential trace mineral present in a rock, soil, air and water. Zinc is used in alloys such as brass, nickel silver and aluminium solder. Large quantities of zinc are used to produce die-castings which are important in the automobile, electrical and hardware industries. It is also used extensively to galvanise other metals such as iron to prevent rusting. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment. Zinc sulfide is used in making luminous dials and fluorescent lights.

EXTRACTION AND REFINING PROCESS:

Roasting and sintering; electrolysis and smelting, require the prior removal of sulfur in a reaction:
