The ultimate goal of this study is to develop a set of polymeric materials that could function as raw material for FDM printing hand prostheses.
Blending TPU with other (heat resistant) materials, such as polyamide, helps to overcome this issue [6].
Mechanical properties of different PA-12 based materials.
The studies will then continue with perfecting the current formulae regarding the materials’ mechanical properties and the materials’ FDM printability.

But the efficiency of material removal is reduced.
Therefore, the ideal polishing water pressure should be based on the polishing parameters, such as the performance of different polished materials, the hardness of the abrasive particles used, and the jet incidence angle etc.

WangWei, LF Xing found that as the magnet height increases, the level of the target materials surface magnetic induction intensity increasing amplitude gradually become smaller, but to target surface level magnetic induction intensity distribution uniformity of no effect.
Pole shoe optimization In order to increase both magnetic effect, generally with the high permeability of materials must be the shape of the pole shoe, by its balance and lead magnetic effect to change the target surface magnetic field distribution[10].
He also found that, different materials, different shapes of the permeability piece magnetic conductivity to the system the impact is not big.

Researches on lightweight materials of ladle lining are limited, R.
Al2O3 micro-powder, nano-Al2O3 powder (D50=30nm) and carbohydrate polymers were chosen as the main raw materials.
Raw materials were mixed according to the ratio in Table.1, and a certain amount of water was added.

The controllable use of landscape materials can effectively reduce "carbon emissions", which can be achieved through the following measures: It is better to use landscape materials with good durability, since the application of long service life and simple maintenance materials means to save energy while reduce the generation of solid wastes.
It is better to use sustainable raw materials of woods, of which the well-managed plantation woods should be surely selected to avoid cutting down the primeval forest; landscape materials of heavy industry are generally of high energy consumptions, and therefore without affecting the properties and service life of landscape materials, low-energy landscape material should be selected.
It is better to purchase locally produced landscape materials, of which the transportation not only consumes energy, but also produces pollution, thus it is better to purchase locally produced materials[6].

This research offers information and a methodology which may be applied in practical conditions for a large number of parts manufactured from the different polymeric materials and for several technological constraints.
Polymeric materials are nowadays widely employed as much for the manufacturing of a lot of daily objects as in the high-tech sector.
These materials are well known for the extremely complex behaviour strongly depending on the time and the temperature.
The mechanical properties, among all the properties of plastic materials, are often the most important properties because virtually all service conditions and the majority of end-use applications involve some degree of mechanical loading.
Alignment of the milling guide relative to the strain gage rosette is accomplished by inserting a special-purpose microscope into the guide’s centering journal, and then positioning the guide precisely over the center of the rosette by means of four X-Y adjusting screws [3].

After being grouted in grouting pipes, solid concrete material will be filled in internal steel pipes.

The process of remanufacture in supply chain management has already obtained some producers and managers' value, but actually has not obtained the corresponding attention and the research in the industrial engineering and the management science research area.
When the products are damaged to the extent that they cannot be used or repaired or the service life is expired, the original method is to collect, disassemble and classify these discarded products, then to recycle them as recycled materials or to abandon them as wastes.
Fig. 1 Reproduction flow chart From an economic perspective, the original handling wastes a lot of manpower and material resources，but the benefit is produced by raw materials recovery is very little.
The main content system integration frameworks follows: (1) MRP (Material Requirements Planning) layer is the planning that divide variety of enterprise products into separate material and related materials, according to different periods of time to determine material requirements, thus it can solute the inventory items and organization of production.
