Purpose Mechanical properties such as tensile, yield, impact strengths, and development of residual stresses play an important role intooling applications. The objective this paper is to investigate the effect layer thickness – one influential process parameters in stereolithography (SL) process, on mechanical SL components. Design/methodology/approach Test specimens are constructed per ASTM standards for different thicknesses 5000 machine, using epoxy resin CIBA tool ® SL5530, a high...

The aim of this study is to estimate the stature a person from morphological facial height and physiognomic heights. Determination can be done in forensic anthropology. Stature estimation an important parameter when human remains such as mutilated bodies or only skull are bought for medico-legal examination. It differs with age, sex race. Each race requires its own formula because racial ethnic variations exist one population cannot entirely applicable other population. possible help these...

Fused Deposited Modeling (FDM) is one of the Rapid Prototyping (RP) processes that use thermoplastics to fabricate parts layer by layer. The built using ABS M30 plastics FDM shows anisotropic property. This direction-dependent failure criterion results in with strength lesser than maximum possible available strength. Also orientation for building selected proprietary software based on minimum fabrication time and material consumption. When it comes sand casting patterns, tensile density play...

In this study, an attempt has been made to fabricate 3D polymer composite scaffolds through additive manufacturing and sintering techniques. Initially, PLA molds were printed using fused deposition modeling (FDM), subsequently, these filled with Polyetheretherketone/Graphene oxide/Hydroxyapatite (PEEK/GO/HA) slurries different wt% of 0, 10, 20, 30, 40 HA. The the then placed in a machine, where pattern was burned out. Finally, desired scaffold fabricated process. sintered surface morphology,...

Abstract In the dynamic era of advanced manufacturing technology, laser powder bed fusion (L-PBF) have gained popularity in different domains due to its capability build parts from bulk miniature size with higher efficiency and precision. Ti–6Al–4V, a bio-inert metal alloy, possesses unique blend profound mechanical biocompatibility attributes, making it highly suitable for implant applications. This study reports fabrication Ti–6Al–4V alloy application via L-PBF process. The objective is...

The high strength-to-weight ratio is the major cause in engineering components' application for automobile, aerospace, marine industries, etc. inclusion of ZrO2 reinforcements AA6061 improves hardness and tensile strength composites that could be used automotive engine components such as piston, cylinder liners, present investigation focuses on fabrication metal matrix reinforcement with various weight ratios (0, 3, 6, 9, 12%) particles by stir casting process. Inorganic salt like potassium...

The major goal of this study is to look into friction stir welding process parameter optimization with the combined decision model, tensile strength best combinations higher. recommended hybrid strategy for order preference by similarity ideal solution (technique an solution) and grey relational analysis method are used discover optimum parameters. It also suitable aluminium alloy A319 Tool rotational speed (r/min), Feed (mm/min), diameter tool pin (mm) all considered while using process....

Fused deposition modeling (FDM) has many different levels of parameters hence prediction method is required for FDM users. The main aim this paper to predict the mechanical strength components before fabrication process. In paper, most influenced process Layer thickness, Infill density, print speed, temperature and build orientation were considered tensile fabricated part. test specimen (ASTM-D638) was by with PLA (Polylactic Acid) material, based on central composite design. actual values...

The influence of carbon at dislocation cores in α-Fe is studied to determine the Peierls stress, i.e. critical stress required move 0 K. effect on both edge and screw dislocations investigated. A coupled molecular statics (MS) extended finite element method (XFEM) employed for this study, where core modeled atomistically. results pure Fe are found be good agreement with a fully atomistic study. approach captures right behavior significantly reduces size region, while describing single an...

The aim of this study is to estimate the stature from nasal height, depth and breadth by deriving a formula. Stature an important parameter in medico-legal examination. It happens many times when highly decomposed or mutilated bodies sometimes only facial remains skull are brought for examination including age ,sex race. Each race requires its own formula estimation because racial ethnic variations exist one population cannot be entirely applicable other population. can possible with help...

Stature is an essential measurement in anthropometry that resolves individual representation of the body. Forensic determination resolution origin, sex, and natural height. Many previous study has been done on estimation height using various measurements teeth skull. The aim this was to estimate stature from head circumference derive a linear regression formula between them. conducted Saveetha Dental College among 70 1st year students (35 males 35 females). measured stadiometer measuring...
