Case Study—Magnetic Cushion Belt Conveyor The belt conveyor is the continuous equipment for transporting materials through the movement of the conveyor.
The material is on the conveyor with the conveyor moving together.
The bearer between the idlers and conveyor is the main direction for improving the belt conveyor to carry out radical innovation, so, this article only lists the corresponding idler technical system of bearing materials.
The magnetic floating belt conveyor can be designed in order to reduce contact and friction consumption based on the ordinary rubber material belt conveyor.

Introduction Thermoelectric materials able to convert thermal energy directly into electrical energy attract many attention.
A deeper understanding of the dimension of materials that affects the figure of merit has recently led to rapid growth and exciting innovative breakthroughs in the field in the last decade [1,2].
The thermoelectric power factor is commonly used to evaluate the performance of thermoelectric materials, especially for thin films.

Young’s modulus was estimated from rule of mixtures for two-phase materials.
Material properties are often used to analyze the machining behavior of machinable ceramic materials [2-3].
Ce-ZrO2/CePO4 materials are taken for evaluation example.
Thus, the evaluation result of CePO4 is “easy” to machine among five materials.

After years of development, Additive Manufacturing will face a good market prospect as the manufacturing equipment, materials and process have become more and more mature.
Introduction Additive Manufacturing( AM, also known as 3D printing) technology is making solid parts with material gradually accumulated technology, which is a method of producing a "bottom-up" compared with the methods of traditional cutting materials . 
The characteristics of AM modeling Modeling should be fully taken into account , and the suitable printing process and materials should be adapted.
The process characteristics of AM and molding material properties of 3D printers  should be put into account, the sizes of the parts should be made into variables ,the corresponding reference value should be set according to the actual working experience.
