An Analysis on Finding the Optimum Die Angle of Polylactic Acid in Fused Deposition Modelling Nor Aiman Sukindar1, a *, Mohd Khairol Anuar Mohd Ariffin2, b 1Mechanical Department of Polytechnic Kuching, Sarawak, Malaysia 2Department of Mechanical and Manufacturing University Putra Malaysia, Malaysia aaiman@poliku.edu.my (Corresponding Author), bkhairol@upm.edu.my Keywords: Die Angle, Fused Deposition Modelling, Natural Convergence Angle Abstract.
Pressure drop need to be observed as it affects the road width of scaffold design, thus affecting the quality of the extruded part.
The main interest in this study is analyzing the factor that effect of producing a precise product, thus focuses on the die angle which to find the optimum angle or natural convergence angle (2θo).
Pressure drop need to be concerned as it affects the stability of the flow along the liquefier length.
A material used in this study is Polylactic acid (PLA) and the physical properties of the PLA material need to be set in the FEA simulation.

Introduction Porous Si3N4 ceramics with rod-like b-Si3N4 grains show superior mechanical properties, such as high strength, good thermal shock resistance, and high strain and damage tolerance[1,2], resulting them promise candidates for various applications, especially at high temperatures.
Characterizations of the starting power, such as particle size, purity, composition and so on, are the most important factors that affect microstructures and mechanical properties of the sintered samples.

With the progress of corrosion, the expansion volume of rust products, which is about 2–6 times the volume of the rusted steel, produces increasing mechanical forces to the surrounding concrete which eventually leads to damages to the structures such as longitudinal cracking, spalling and delamination of concrete cover and loss of the bond between concrete and reinforcement [2].
Chunhua Lu[12] developed a mathematical model in which the influence of the mechanical properties of the corrosion products on cover cracking and the amount of the corrosion products accommodated within the radial open cracks were considered.

It is essential to predict and control these characteristics through the chosen AM process, and to ensure mechanical performance that is at least comparable to the existing one.
However, other factors may contribute to porosity, such as pure CO2 acting as a shielding gas that dissociates to release oxygen and increases the risk of oxidation [5].

It is unclear how dislocations form during rapid solidification, how they change during loading, and the overall significance of various microstructure features (cell spacing, microsegregation, dislocation structures, grain boundaries) in creating the unique mechanical properties of AM 316L steel [15].

Fig. 2 Meshing of Connection plate and Wheel bracket Motor locate the connection plate and the wheel's decisive factor is the material strength, using material directly affect the overall strength whether meet the requirements.
High strength, especially in normalizing or normalized and tempered condition have higher comprehensive mechanical properties. [2] The ANSYS Structure analysis In accordance with the due to the drive wheels need to be large enough radial force, thus the motor and wheel is the main stress components, the main effect of the hydraulic cylinder so provided by the fluid pressure in motor positioning connecting plate, and then through the motor output shaft is passed to the wheel, so the analysis process, motor positioning connection plate and the wheel requires the finite element analysis.

The enhancement of mechanical properties obtained in the studied soil-fiber systems demonstrates the potential application of these composites in geotechnical works.
In this sense, a lower probability of reorganizing and a good interconnection of soil particles are important factors in obtaining higher values of the shear strength parameters [42].

There have so many factors can induced vibration, such as rolling part, rolling technology, rolling equipments, and control system.
In fact, all of the factors can induced the vibration of rolling mill above mentioned, which make the vary of the rolling forces, and excite the rolling equipment system ,and further makes the rolling equipment system vibrations.
The trend directly affects the accuracy of the signal, and should be eliminated.
As the rolling mill random noise factors by many uncertainties, it can be assumed to have the normal characteristics.
For the stationary stochastic excitation model, as long as the mean and correlation function, or mean and spectral density determined, the statistical properties can be fully determined.
