Additive manufacturing (AM) can be used without the need of any moulds or tooling, and are very suitable for manufacturing one-piece or small batches of with complex external shapes and internal structures within a short lead time, which are difficult to make or even cannot be fabricated by the tooling and machining processes. The manufacturing of metal parts by sand casting method is a tedious process when considering low volume manufacturing where it took lot of time, design cost, material cost etc., In this paper, the web gland component has been prepared using stainless steel by varying the different process parameters such as scan spacing, laser power and layer thickness in selective laser sintering (SLS) process. By using vickers hardness tester, the hardness and the microstructure of component also analyzed and it is compared with the same component properties prepared by using sand casting process. From the comparative result, it was found that the hardness of material increases by 12.5% on sintered part than casting part.Keywords: Use about five key words or phrases in alphabetical order, Separated by Semicolon.
Purpose: The current study is to examine the behaviour of customers towards online shopping, to analyze the satisfaction of the customers towards online shopping and to measure the problems faced by the customers while buying goods in online shopping.

The difficulties encountered by internet shoppers were analyzed across different sites. Design/methodology/approach: The study is descriptive and carried out in Krishnagiri district, Tami Nadu. The district connects Karnataka, Andra Pradesh and Telangana with Tamil Nadu. The study has been done to comprehend the awareness of the customers towards online shopping consisting of behaviour, satisfaction and their opinion on different problems faced by them while buying in the retail market. 200 sample respondents across the districts have been selected using a convenient sampling method. The customers using online shopping for buying electronic goods and their accessories like mobile phones, television, laptop, etc., are purposively selected to identify the unique characteristics of the customers towards online shopping. Findings: The personal interview has been conducted with each respondent. The collected primary data are analyzed with the help of SPSS software using simple percentages, descriptive statistics, Fried man test, ANOVA, Z test and factors analysis. The recommendations will raise customers' general enlightenment about internet buying in general. Research, Practical & Social implications: As customers want to avoid infection and risk with Covid-19, the study's consequence aids researchers and businesses in fast adapting and adjusting their marketing approach, with an emphasis on digitalization. Originality/value: Online merchants can learn more about customer habits according to this research. As a result, shoppers will have fewer issues when using the site, and their confidence in it will grow, resulting in more purchases. The study concluded that the ranks given for the varieties of brands and products available and offer and discounts offered are important factors to influence the customers' minds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
