Mechanical properties of 3D printed parts depend on various parameters and settings of 3D printing, such as layers’ thickness and height, shell thickness, filling factor, etc. [13-18].
Mechanical properties of 3D printed parts were investigated by Bellini et al. [19].
Es-Said et al. investigated the influence of layer orientation on the mechanical properties for the 3D printed parts [21].
The filling factors were 20%, 40%, 60%, 80% and 100%.

The mechanical properties of the duplex silicide, such as fracture toughness and high temperature strength, show strong orientation dependence, thereby suggesting the importance of the control of microstructure to improve their properties.
Three-point bending tests at room temperature and compression tests at 1400 °C were conducted to examine the mechanical properties.
However, the results obtained by the addition of Zr suggested the existence of other factors that may control the misfit strains.
This refining of the microstructure might be beneficial in improving the mechanical properties of the duplex silicide.
Thus, the control of microstructure plays an important role in improving the mechanical properties of the duplex crystal.

Comparative Study on Mechanical Properties of Jutecell, Cotton and Bamboo Fiber Knitted Fabrics 20 Lina Chen 1, a, Fanrong Kong 1, b, Ruichao Xu1,c 1 Department of Textile Engineering, Henan Institute of Engineering, Zhengzhou 450007, P.R.China alina0305@126.com, bkongsiru243@163.com, crcxu@163.com Keywords: Jutecell, cotton, bamboo fiber, mechanical properties.
The Tab.1 shows that the specification parameters of three types of fabric make little difference, at the time of testing the mechanical properties of them, they can be regarded as the same specifications.
Factors influencing the abrasion resistance of fabrics include: fiber characteristics, such as fiber length, fineness and cross-section shape; yarn properties, moderate yarn twist , uniform evenness.
The process of fabric pilling can be broadly divided into of rising, struggling into a hair-ball, shedding three stages; the pilling properties of the fabric can affect the garment's appearance and durability.
Conclusions The mechanical properties of jutecell fibers are the best, followed by bamboo fibers, and cotton is the worst.

Mechanical properties tests The mechanical properties of WNC fabrics measured were breaking, tearing and peeling strength.
Many factors are believed to affect the peeling strength fluctuation and these factors can be divided into two main categories: the space between warp-knitted fabric and non-woven fabric and hot melt powder.
The testing results show mechanical properties of these WNC fabrics have little change after different high temperature heat treatment.

EFFECTS OF PARTICLE SIZE AND SIZE DISTRIBUTION ON THE MECHANICAL PROPERTIES OF EPDM/SILICA VULCANIZATES M.N.
This fact could explain why the mechanical properties of the EPDM filled with Si-200 are not in between the values of the compounds filled with Si-150 and Si-250.
During the last years, the effects of different types of fillers on rubber compounds have been studied, in search of improvements on its physical and mechanical properties.
These values are affected by several factors such as surface reactivity, which determines the polymer-filler interaction, aggregates, size and shape of the particles, structure and filler particle dispersion [7].

As the action mechanisms of various factors affecting concrete durability are different, it is difficult to understand the durability of concrete exposed to multiple factors using only mechanism analysis.
Concrete failure caused by non-mechanical factors is similar to that caused by loading.
This conversion allows us to establish a mechanical model for the durability degradation process of concrete exposed to multiple factors.
