Quarrying is quite simply the extraction of natural resources from the earth, usually from some form of surface working or quarry site. Quarries produce a range of useful materials, including limestone, dimension stone and rock. In Australia, the most common materials extracted are construction aggregates such as crushed rock, sand or gravel.
What is a prototype? A prototype could be defined as a real 3D model or physical proof of the viability of a product, which facilitates the fault detection in the design. A 3D printed copy of the packaging design is a "prototype", as a model made of paper and glue of a new toy.
