Additive Manufacturing Viewed from Material Science: State of the Art & Fundamentals J.Y.
In fact, AM technology, in spite of its significant economic impact in manufacturing has not yet drawn strong interest from material science perspectives.
Furthermore, the feature size realizable is greater than 2mm and only materials that are available in wire or ribbon form can be used.
· For AM functional gradient materials, the transition zone strategy in relation with alloy compositions and process parameters

It should be understood that in view of the variety of structures of composite materials, the mechanisms of their destruction must be investigated separately for layered [1-4, 10], 2-D and 3-D woven [5-8, 12-14] materials, as well as for materials reinforced with short randomly directed fiber [17-20].

Footwear nesting were based on its design pattern and manufacturing materials, the results of nesting influence the products quality and cost directly.
Because the clothing sample size are generally apparels, and the used materials are unitary.
Pattern recognition with materials is point to digital expression model in a computer; it’s the premise of Computer Aided Nesting.
Rectangle method is the most commonly used method for most materials, but for those with rectangular shape far parts, only combined different or same parts into an approximate rectangle, so as to improve the utilization rate of materials.

Composite materials refer to engineered or naturally-occurring materials made from two or more constituent materials with significantly different physical or chemical properties.
To ensure the sustainable development of building materials, the key is research and development and promote the use of green building materials.
