The factors affecting the print quality of green part are considered.
Article purpose: the development of filament for 3D printing of green parts, analysis of factors affecting the print quality and the research on the influence of the filament supply coefficient on the geometry of green part during 3D printing.
Factors affecting the print quality can be divided into two groups.
As a result, there may be gaps between adjacent layers or vice versa, the influx, which dramatically worsens the geometrical accuracy of parts and their mechanical properties.
Factors affecting the quality of 3D printing of green parts can be divided into two groups: controlled and uncontrolled.

The results showed that the Cf/Al-Cu composites had better mechanical and tribological properties compared to Al-Cu alloy.
However, most investigations of Cf/Al composites focused on the interfacial improvement and mechanical properties [4].
Mechanical Properties Table 1 is the density, hardness and ultimate tensile strength of the specimens.
Conclusions (1) The incorporation of carbon fibers in Al-Cu alloy improved the mechanical and tribological properties greatly

When the temperature change and under the influence of external factors, many materials can move from one state to another, thus significantly changing its structure and physicochemical properties [1-4].
All of these factors significantly affect the restructuring of the supramolecular structure and, as a result, on a variety of properties of the polymer material, leading to the improvement or deterioration of its specific technical characteristics [5].
It can be established from the data and analysis, that the effect of irradiation on strength and inelastic properties of polymers is significant, and first of all, it affects the amorphous phase of the material [9-11].
Thus, the effect of electron irradiation, load and temperature on the mechanical properties of Mylar film is very important and is described in the framework of exponential models.

Based on test and analysis results of the structural parameters, the relevant performance indicators were measured in consideration of mechanical properties,comfort and style of fabrics, and the test data were systematically integrated and the relevant quantitative data were ultimately obtained.
As to the main factors of the structural parameters which greatly affect the performance of the fabrics, they will provide scientific evidence for the design and development of fabric.
Correlation Analysis of Structure and Properties on Fabric.
Comparison of mean value is the relationship between a parameter and a property, but a property affected by the overall structural parameters or a structural parameter affects the overall properties.
The performance changes are often caused by a variety of complex factors, thus the result of dispersion and volatility is relatively large; the partial correlation will be truly reflected unless the other factors are removed when partial correlation analysis is adopted.

In this work the influence of value of single draft on mechanical-technological properties of high carbon steel wires was evaluated.
The selection of the individual draft magnitude depends on numerous factors, which include the following: the plasticity of material and its structure, and the conditions and mode of deformation [1-2].
Variation of mechanical properties of wires drawn according to Variants A, B and C as a function of the total draft.
Therefore, wires drawn with large drafts (Variant A) are characterized by much higher mechanical properties.

The influence of micro-bridge structure on the device performance was studied and simulation results showed that the bridge leg shape and width affected mainly on the thermal and mechanical properties of device.
A compromise design between the thermal and mechanical properties was obtained in order to maintain the best performance of the device.
By contrast, it can be found that besides the shape of the bridge leg, its width is also one of the major factors influencing the mechanical property of microbolometer.
In other words, widening the leg is beneficial to the improvement of mechanical property.
A compromise design between the thermal and mechanical properties should be considered in order to maintain the best performance of THz wave detector.

Mechanical property of cement mortar was bad.
It would play a great impact on mechanical properties of cement mortar to improve interface bonding performance of RFA-cement.
The compatibility of admixtures had a significant impact on mechanical properties.
Table 6 shows that the admixtures play a larger impact on mechanical properties.
Compared to sample M7, the compressive strength of mortar sample M8 is increased by 80% and it indicates that compatibility of additives is a major cause which affects mechanical properties.
