This paper aims to optimize three mechanical properties such as strength, elongation, and modulus of elasticity.
However, PLA ensures good processing performance and acceptable mechanical properties through FDM production [7].
Also, most of these researches only consider one or a few response factors at a time.
An ANOVA analysis was also utilized to identify significant contributors in each mechanical property intended to be optimized. and these data were further processed to develop a topology diagram with the significant contributors as main factors.
Kafsghar et al. conducted a four (4) parameter optimization of mechanical properties [13].

Austempered vermicular-graphite iron seems to be a perspective material because of its promising mechanical properties.
These properties are strongly affected by parameters of applied heat treatment.
The difference in the length of the austenitizing times that affects the saturation of austenite by carbon from graphite particles (here 30 and 90 minutes) had not any influence (or not significant) on mechanical properties or structure.

The resulting mechanical properties are strongly affected by the heat treatment parameters.

The purpose of this research is to examine how the size and quantity of water hyacinth (WH) fibers impact their reinforcement of bio-based epoxy resin, with a specific focus on how these factors influence mechanical properties.
However, the main problems of bio-composites are the poor mechanical properties, limited barrier capabilities and thermal stability [8,9]. [8], [9].
In addition to modifying the surface of the fibers, it is essential to consider factors related to particle size.
Photographs of the specimen in each different composition Mechanical properties test.
Overall, it becomes evident that the size of the WH fiber does not affect hardness; conversely, the quantity of WH fiber directly influences the hardness properties. [18] Table 2.

Abstract.
Humidity is a crucial environmental parameter that can profoundly influence the properties and performance of plastic materials.
For this reason it is important to evaluate the moisture absorption properties of plastic materials.
Its impacts also affect the items' mechanical, thermal, and chemical properties, rather than just their aesthetic or visual elements [5].

It was shown that the rolling of the alloy leads to strong anisotropy in mechanical properties.
The effect of the deformation structure on the mechanical properties and their anisotropy is discussed.
As a result, the work hardened Al-Mg-Sc-Zr alloy may exhibit anisotropy of mechanical properties, which affects the formability of [6].

The fine coherent Al3(Sc,Zr) particles do not affect the changes in mechanical properties and anisotropy during isothermal rolling.
