A convex mirror is a piece of a sphere with reflective part on the outside (outer deformation out). They are also known as diverging mirrors, that is, light rays coming from a point, to be reflected, and not away intersect each other. For this reason the convex mirrors are not actual images. Convex mirrors for signaling can be installed both outdoors and indoors, Dependon the material. These mirrors are designed to see and be seen, particularly suitable for areas with low visibility to prevent accidents of pedestrian traffic, vehicle traffic and surveillance. can also be used for:
- Parking lots or parking
- Streets dangerous crossings
- Department Stores
- Shops and businesses
- Supermarkets
- Hospitals
- Factories and industries
- Piers
- Office buildings
- Schools
- Museums

Before deciding to mirror needs, you should always take into account the following parameters:

1. Distance between the observer and the mirror. That is, the distance at which the observer will be the mirror when viewing.
2. Number of addresses to be controlled.

We attach some approaches depending on the diameter of the convex mirror.

• diameter mirror 450mm -> 6 meters away from the mirror.
• 600mm diameter mirror -> 8 meters away from the mirror.
• 800mm diameter mirror -> 10 meters away from the mirror.
• 1000mm diameter mirror -> 14 meters away from the mirror.

ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).
