Then, the resulted films were characterized on their optical, structural, and photovoltaic properties.
Therefore, in the detailed study, we investigated the effect of those layers on the optical, structural, and photovoltaic properties of BiOI films.
Due to the covalent bond in all atoms, BiOI has good optical and mechanical properties.
We assumed that the insertion of TiOx and TiO2 might affect the shunt resistance value (Rsh) and it had an impact on the open-circuit voltage enhancement.

Introduction The properties of fused deposition modeling (FDM) built parts exhibit high dependence on process parameters and can be improved by setting parameters at suitable levels [1,2].
The study may be useful in situations where sliding contact of mating surfaces occurs e.g. gears, journal bearings, seals, cams, etc. when conventional parts is replaced with FDM processed parts due to easiness of fabrication, economic production of prototypes, light weight and high specific mechanical properties.
Like other mechanical properties, wear is also dependent on internal resistance of part against the external forces.
For improvement in process part properties, it is necessary to propose the optimum parameter setting.

There are numerous factors that have an influence on the accumulation process including temperature or a loading program [4].
Mutual interactions of strains and stresses being accounted in the energy based approach description make it difficult to define unequivocally cyclic properties of steel P91 on the basis of the process of strain energy changes.
Conclusions On the basis of plastic strain energy ΔWpl analysis, in the function of the number of loading cycles, can be said that P91 steel is characterized by changes in cyclic properties.
It is difficult to identify the cyclic properties of the investigated steel on the basis of unequivocally energy change ΔWpl.

Elastic properties.
Elastic properties determine the properties of the material that undergoes stress and present the important information concerning the nature of the force operating in solids.
Furthermore, the most elastic properties of applications are presented by the Zener anisotropy factors (A) which present a measure of the anisotropy of the elastic wave velocity in a crystal, Young’s modulus (Y) who describes the material’s response to linear strain, The Shear modulus (G’) describes the material’s response to shearing strain and Poisson ratio υ.
