In basic terms, it builds a design space from a model (3D model). To make the design more efficient, it then eliminates or displaces material inside it. By defining cavities in continuous design domains, topology optimization is an excellent technique for generating lightweight, high-performance, and cost-effective structures. Like every other optimization problem, it needs some boundary conditions, constraints, an objective function, and criteria to attain optimality, which must be decided by the type of design we are making, material costs, mechanical performance, and resistance to failure. Since there are several iterations in the optimization rounds which allow us to play with variables within the boundary conditions to come up with an aesthetically pleasing, mechanically optimized design. We are in hope that the proper implementation of this would lead to the betterment of society.</jats:p>     </jats:abstract>  <publication_date media_type='online'>     <month>07</month>     <day>30</day>     <year>2023</year>   </publication_date>   <pages>     <first_page>114</first_page>     <last_page>127</last_page>   </pages>   <crossmark>     <crossmark_version>CC BY-NC-ND 4.0</crossmark_version>     <crossmark_policy>10.35940/BEIESP.CrossMarkPolicy</crossmark_policy>     <crossmark_domains>       <crossmark_domain>          <domain>www.ijrte.org</domain>       </crossmark_domain>     </crossmark_domains>     <crossmark_domain_exclusive>true</crossmark_domain_exclusive>     <custom_metadata>       <assertion explanation='Journal Name' group_label='Journal Name' group_name='Journal' name='Declaration' order='0'>International Journal of Recent Technology and Engineering (IJRTE)</assertion>       <assertion explanation='Funding' group_label='Funding' group_name='Funding' name='Declaration' order='1'>No, I did not receive any financial support for this article.</assertion>       <assertion explanation='Conflicts of Interest' group_label='Conflicts of Interest' group_name='Conflicts-of-Interest' name='Declaration' order='2'>No conflicts of interest to the best of our knowledge.</assertion>       <assertion explanation='Ethical Approval and Consent to Participate' group_label='Ethical Approval and Consent to Participate' group_name='Ethical-Approval-and-Consent-to-Participate' name='Declaration' order='3'>No, this article does not require ethical approval and consent to participate with evidence.</assertion>       <assertion explanation='Availability of Data and Material' group_label='Availability of Data and Material' group_name='Availability-of-Data-and-Material' name='Declaration' order='4'>Not relevant.</assertion>       <assertion explanation='Authors Contributions' group_label='Authors Contributions' group_name='Authors-Contributions' name='Declaration' order='5'>All authors having equal contribution for this article.</assertion>     </custom_metadata>   </crossmark>   <doi_data>     <doi>10.35940/ijrte.F7462.0712223</doi>     <resource>https://www.ijrte.org/portfolio-item/F74620311623/</resource>   </doi_data> </journal_article>
