However, one of drawbacks of this technology is the shortage of applied materials.
Selective laser sintering (SLS) is one of popular techniques for solid freeform fabricate-on processes of RP since it can produce solid parts with arbitrary geometric shapes through consolidation of layers of powder materials by using thermal energy supplied by a focused laser beam.
Experimental procedures and test results Base Materials.
For simplification, the effects of environmental influences and materials were fixed.

Nanometer ZnO and nanometer CeO2 have good UV radiation absorption, but they have difficulties in dispersing in polymer materials.
Experimental Materials and equipments Material: polyamide 6 semi-dull chips, nanometer zinc oxide and nanometer cerium dioxide, additives, etc.
Then the mixed materials were melted, mixed and extruded into a big filament which was cut into chips.
In addition, we used the ash extraction method to test the quantity of the nano-materials contained in the chips.

Nickel based super alloys are promising materials for high temperature structural applications because of their low density.
In fact, hetero-epitaxial growth is the key technology that enables material science engineering, which is the ability to tailor properties of material.

Supply Chain Supply chain is defined as a network of corporate organization in order to improve and enhance the flow of information and material between customer and supplier with the consideration of lower price and highest speed.
Environmental indicators cover performance related to inputs (e.g., material, energy, water) and output (e.g., emissions, effluents, waste).
